Description of the invention (1) The invention is based on a superalloy that exhibits higher temperature mechanical properties, especially useful for casting single crystal water turbine guide vanes Leaf fragment) superalloy. Compared with polycrystalline water turbine guide vanes, single crystal water turbine guide vanes demonstrate excellent turbine engine performance and lasting benefits. For detailed discussions, see P. Burkholder et al. Of A 1 1 i S ο η Engine Company, K. Harris et al. Of Cannon-Muskeg on Limited, 3rd Int. Charles Parsons Turbine Conf. Of Proc. Iom, UK 1995 "Allison Engine Testing CMSX-4⑧ Single Crystal Turbine Blade & Guide Blade" by Newcastle-upon-Tyne, April 25-27, 2014. The improved performance results of single crystal superalloy components are excellent thermal fatigue, low cyclic fatigue, creep strength, oxidation, covering properties of single crystal superalloys, and no crease boundary single crystal alloys in single crystal water turbine guide vanes. In comparison, there is a significant improvement in the creep characteristics of thin walls (cooled airfoils). In any case, single crystal components require a narrower range of crepe lacking endurance, such as low-angle and high-angle boundaries and solution heat treatment-causing recrystallized crepe, which reduces the production of castings and increases manufacturing costs as a result. Due to the higher castings produced, directional solidified castings with columnar nickel base superalloys have been successfully used to replace the first-generation (without chain) single crystal alloys at a cost saving. In any case, due to the crease boundary in the non-aerofoil area, especially inside and outside cables of most aerofoil segments that indicate high complex stress conditions, the azimuthal solidification member is more disadvantageous than the single crystal vane. Due to the possibility of lower mechanical processing and manufacturing costs, most of the airfoil sections are 0 · 丨丨 for the design engineer of the turbine (please read the precautions on the back before filling this page) ------- Μί.0 --------------------: ___ * ·

CMSX®-681 is an experimental nickel-base superalloy. Compared with the single crystal CM 186 LC® alloy, this alloy is considered to have improved creep strength. CMSX®-486 is a nickel-base superalloy (according to the invention), which is similar to CM_186 LC⑧ and CMSX®-681. However, compared to the CMSX®-681 crystal, the single crystal casting of the CMSX®-486 alloy shows surprisingly better stress failure and creep failure characteristics. The stress-damage characteristics printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs are evaluated by casting test strips of each alloy (CM-247LC®, CMSX-3®, CM 186 LC®, CMSX®_681 and CMSX®-486). And then the auxiliary samples (test strips) are prepared by the fixed installation of each alloy at the selected time. The stress failure characteristics are determined by the typical lifetime (mean time to failure, hours). Directional solidification CM 247 LC® test strips are heat treated for 2 hours at 2230 ° F, 2 hours at 2250 ° F and 2 hours at 2270 ° F, and 2 hours at 2280 ~ 2290 ° F, air cooled or Partial solution of gas-inflammation, aging at 1600 ° F for 20 hours, and air cooling.

Description of the invention ( n) The results show that the cmsx®-486 test strip shows significantly improved stress failure characteristics at 36 psi load at 1800 ° F compared to the conventional alloy and experimental alloy CMSX®-681. Under 25 psi load at 1900 ° F, the CMSX®-486 test strip (according to the invention) performs significantly better than the directional solidification CM 247 LC⑧ and single crystal (SX) CM 186 LC® test strips, and is similar to the CMSX-3® test strips. . In any case, compared to the CMSX-3® single crystal casting, the CMSX®-486 single crystal casting can be manufactured at a considerable cost of deposits, which is discarded due to fewer crease defects. Furthermore, CMSX®-486 components show excellent stress failure characteristics, whereas CMSX-3® components require solution heat treatment. The CMSX®-486 test strip shows significant improvement in stress failure characteristics when compared to a directional solidification CM 247 LC® and single crystal CM 186 LC⑧ test strip and an experimental CMSX⑧-681 test strip at a load of 12 ksi at 2000 ° F. CMSX®-486 test strip (according to the invention) has a typical lifetime of approximately 65% CMSX-3® test strip at 2000 ° F at 12ksi. In any case, it is estimated that single crystalline components cast from CMSX⑧-486 alloy (casting) will have approximately half the cost of single crystal components (from CMSX-3® crystals (solution heat treated)) because fewer crepe defects are discarded. Therefore, it is possible that the casting of components of the CMSX®-486 alloy will have a very significant cost, which far exceeds the single crystalline components cast from the CMSX-3® alloy, even at application temperatures as high as 2000 ° F. Another set of test strips from CMSX®-486 alloy was added to the stress failure test. The part of the test strip is a local solution heat treatment and double curing, and the other part of the test strip is double aged as-cast. Partial solution heat treatment was completed at 2: 260 ° F for 1 hour at 2280. It is completed in 1 hour under F, which is caused by air cooling or gas instigation. Double maturation includes the application of Chinese National Standard (CNS) A4 specifications (21〇2 ^ & mm) in 1975

Description of the invention (* * Possible sample defect results Table 6 is also illustrated in the first to eighth figures. Each of the first to eighth graphs shows the existence / dislocation (degrees) of the low-angle Chu-continuous boundary (LAB) or high-angle fold boundary (HAB) on the stress failure life period under a certain temperature and load. (Hour) icon. Each data point in Table 6 is indicated by a solid diamond in the first to eighth plots. The first and second graphs show the Lab / ηαB misalignment at 1742 ° F and 30 ksi and 1742. F and 36 ksi have very little effect on the life of the damage. The curves shown by the solid lines in the first to eighth figures attempt to be approximately squares suitable for at least data. The third figure shows that the LAB / HAB misalignment has a negligible effect of the damage life time rising to 10 degrees, and even at 18 degrees misplacement, the damage life period is about a black fold defect (LAB / HAB misplacement of 00 degrees) Half of a single crystal. This comparison is very favorable for the result of CMSX-3d) (data points are marked with a cross), where a drastic increase in the destruction of life occurs at about 6 degrees of misalignment. At the same time, it should be noted that the CMSX®-486 test slab with single crystal (OO degree LAB / ΒΑΒ dislocation) has a longer failure life than the single crystal CMSX-3® test slab. Furthermore, the CMSX-3® data shows a negative slope from 0.0 to 6 degrees, whereas the damaging lifetime of CMSX®-486 is nearly constant and rises to 6 degrees. The fourth figure is shown at 1800. In the case of f and 25 ksi, the LAB / HAB misalignment has a very small effect on the damage life time rising to 18 degrees. The fifth figure is shown at 1800. Similar results at F and 30 ksi. The fifth figure is also shown at i800. F and 30 ksi test cases throughout the entire range of LAB / HAB misalignment, CMSX®-486 alloy provides a better ratio than Rene 'N-4 alloy (this was developed by General Electric and described in the following publication: "Rene, N-4: by Earl R0SS and others have improved oxidation resistance, low-angle boundary strength, and better long-term damage resistance (please read the precautions on the back before filling out this page) -illlllr ^ · ΓΙΙΙΙΙΙΙ «^ I Aw — — — — — — --1 .-------------- This paper size applies to China National Standard (CNS) A4 (210 X Education 7).

Description of the Invention (First Generation Single Crystal Turbine Airfoil Alloy With Improved Oxidation Resistance, Low Angle Boundary Strength and Superior Long Time Rupture Strength) at 2i degrees, 22-26 September 1996, Seven Springs, TMS, Proc, [GE Aircraft Rngines] 8th Int. Symp. Superalloy) provides more durable single crystal castings. The most obvious is that for Rene 'N-4 alloy ,damage The life time decreases very quickly by more than 11 degrees, but the damage life time is generally unchanged over the entire range of LAB / HAB misalignment (0 · 0 to 18.0 degrees). The sixth figure shows that the test slab was added with 1900 ° F and 25 ksi The load only shows a gradual decrease in the damage life time, and the displacement rises to about 22 degrees. The seventh and eighth figures show that even at the conditions of 1922 ° F / 17.4 ksi and 2000 ° F / 12.0 ksi, respectively, the CMSX®-486 test Thick plates do not show a gradual reduction in damage life, which is a characteristic of other single crystal alloy castings. Compared with alloys such as CM 186 LC®, it is believed that this invention (eg CMSX®-486) nickel-base superalloy is better The properties can be attributed to very few chemical properties. In other words, it is believed that increasing the giant (Ta) content of the alloy of the invention provides increased strength (such as improved stress failure and improved creep failure properties) and reduced (Hf) content to prevent excessive 7 / 7 'eutectic phase. Higher macro content is contained by reduced chromium to provide phase stability. The ninth, tenth, and eleventh diagrams show CMSX®-486 (casting) double curing (1975 ° F 4 hours, 1600 ° F 20 hours, Air cooling). The ninth to eleventh figures are optical micrographs at 100X, 200X, and 400X magnifications. The ninth to eleventh figures show that the cast CMSX®-486 has a eutectic phase with a small volume (VF) of about 5% (brighter shades. The paper size applies the Chinese National Standard (CNS) A4 specification (210 X none 7 Public love)

Description of the invention (dark area). The high VF of the eutectic phase results in a lack of toughness. Figures 12 to 14 are electron micrographs of CMSX®-486 (casting) double curing (1975. F 4 hours, 1600. F 20 hours, air cooling). Figures 12 through 14 are electron micrographs of 2,000X, 5,000X, and 10,000 × magnifications, respectively, and show the neat cubic 7 'phase of the CMSX®-486 alloy cast. This is consistent with the excellent creep failure characteristics of CMSX®-486 castings. The twelfth figure also shows that good conditions of carbide formation remain during solidification (ie, no display degradation). When compared with conventional single crystal cast alloys, the alloys of this invention show improved creep strength in terms of properties and have exceptional capacity to accommodate wrinkle defects. As a result, the alloy of the present invention can be very beneficial to use to provide improved casting production and reduce aircraft component costs as well as industrial water turbine mechanism parts (such as turbine turbine vanes, blades, and multiple vane sections).
