It has a structure in which layers of at least two types of fine precipitated particles are formed.
- the processed material is a material obtained by subjecting a dilute alloy in which at least one of Ti, Zr, Hf, V, Nb, and Ta is dissolved to a solid phase with Mo as a matrix, and performing processing such as rolling. It is not a recrystallized material.
- a dilute alloy is an alloy containing a very small amount of a solute element in a solid solution alloy of about 5% by weight or less.
- a method for producing an alloy in which Mo is used as a matrix and in which carbide particles, oxide particles, or boride particles are dispersed and precipitated is known. For example, Ding2 ⁇ ! Alloy @ Ding20 alloy is manufactured by a hot working process of hot extruding, forging and rolling an ingot by arc melting or powder metallurgy.

- the high-strength / high-toughness nitriding treatment of the present invention is manufactured by the following internal nitriding treatments (1) to (3).
- (1) to (3) in FIG. 2 are schematic diagrams showing the structure of the processed material at each stage of the internal nitriding treatments (1) to (3) performed by gradually increasing the treatment temperature.
- (1) First-stage internal nitriding treatment Heating in a nitriding atmosphere at a temperature not higher than the recrystallization upper limit temperature and at a temperature not lower than the recrystallization lower limit temperature—200 ° C. The nitride particles are dispersed and formed.
- the first-stage nitriding treatment nitrogen is diffused into the work material while maintaining the work structure X1 of the dilute alloy work material, thereby preferentially nitriding the nitride-forming metal element dissolved in the parent phase to form a diameter.
- Sub-nano-plate-like nitride particles of about 1 to 2 nm are formed and dispersed in the matrix.
- preferential nitriding refers to a phenomenon in which only the nitride-forming element, not the metal of the parent phase, is preferentially nitrided. Due to the pinning effect of the precipitated particles generated by this nitriding treatment, the recrystallization temperature on the surface of the work material increases.
- the starting TZM alloy work material was nitrided at 1200 ° C. and 130 ° C. for 25 hours, and the grain structures of their cross sections were observed. At 1200 ° C, the same processed structure as that of the non-nitrided material was maintained, but when heated at 130 ° C, a partially recrystallized structure was observed. From these results, since the starting TZM alloy is recrystallized when it is nitrided at 130 ° C. or higher, primary nitriding must be performed at 1200 ° C. or lower.
- Second-stage internal nitridation The results obtained by the first-stage nitridation in a nitriding atmosphere! 5 Heat at a temperature equal to or higher than the minimum recrystallization temperature of the processed gold material to grow and stabilize ultrafine nitride particles. The recrystallization temperature further increases due to the growth and stabilization of precipitated particles by the second-stage nitriding treatment. In contrast to secondary nitriding, which recrystallizes inside the processed material and exhibits a relatively equiaxed grain structure, the surface of the processed material processes and recovers fine and elongated crystal grains.
- the heating temperature condition for forming a two-layer structure in which the tissue is retained is 20.
- Fig. 3 (a) shows the grain structure of this processed material.
- the inside of the work material is recrystallized and the work structure X2 remains, but when the work material is relatively thin (3 mm or less), the work structure can be completely retained inside.
- Fine nitride particles TiN, (Ti, Zr) N, etc. are dispersed and precipitated in the alloy surface area by primary nitridation, pinning the crystal grain boundaries in the alloy surface area and preventing its movement. As a result, the recrystallization is suppressed, so that the processed and recovered structure is maintained.
- the TZM alloy is completely recrystallized by secondary nitridation (1600 ° C) at a high temperature of about 1300 ° C or more. And a recrystallized structure is exhibited. As a result, the present secondary nitride shows a two-layer structure.
- the third and subsequent nitriding treatments aim at further growth and stabilization of the nitride particles while leaving the processed structure X3, and are rod-shaped with a thickness of about 10 nm and a length of about 50 nm.
- the nitride particles are uniformly dispersed in the Mo matrix.
- Partial nitriding treatment The quaternary nitriding is performed at a temperature condition that forms the processed and recovered grain structure to the inside of the processed material. It is possible to end with a third stage internal nitridation process, but in that case it can only be used at lower temperatures than the quaternary nitride. This is because if the difference between the secondary nitriding temperature and the tertiary nitriding temperature is increased (eg, 1200 ° C ⁇ 1400 ° C ⁇ 1800 ° C), recrystallization occurs during nitriding, which is inappropriate, but the difference is reduced. (E.g.
- the reworking temperature of the Mo alloy material of the present invention is higher than that of the conventional TZM alloy. Over 1400 ° C.
- both the primary nitridation and the secondary nitriding are internally nitrided at a temperature lower than the recrystallization temperature of the TZM alloy (about 1300 ° C).
- this is different from the above-described secondary nitride material in that the primary nitridation and the secondary nitridation process completely nitride the inside of the specimen up to the inside and disperse and precipitate fine nitride particles.
- primary nitriding was performed at 1150 ° C for 64 hours
- secondary nitriding was performed at 1200 ° C for 25 hours
- tertiary nitriding was performed at 1300 ° C for 25 hours
- quaternary nitriding was performed at 1600 ° C for 25 hours. It was used as a secondary nitride material.
- Figure 3 (b) shows the grain structure of the quaternary nitride material in cross section.
- a secondary nitride material was manufactured as follows.
- T i C commercial T ZM alloy workpiece which fine particles are dispersed precipitated (Mo- 0.5 ° / oTi-0.08 % Zr-0.03% C) of 1 atm N 2 gas flow, the 1 0.99 ° C, 4 hours After the heat treatment, heat treatment was performed at 1600 ° C. for 25 hours.
- a high vacuum (1. 3 X 10- 4 Pa
- a quaternary nitride was produced as follows.
- the same TZM alloy material as in Example 1 was processed at 1150 ° C, 64 hours (primary nitriding), 1200 ° C, 25 hours (secondary nitriding), 1300 ° C, 25 hours in a 1 atm N 2 gas stream.
- the internal nitriding treatment was performed by sequentially increasing the temperature (tertiary nitriding), 1600 ° C, and 25 hours (quaternary nitriding).
- Comparative Example 1 The same TZM alloy processed material as in Example 1 was recrystallized in a vacuum at 1600 ° C. for 1 hour to grow crystal grains greatly.
- Example 1 The characteristics of the test pieces after the treatment of Example 1 and Example 2 were as follows.
- Figure 4 shows the stress at room temperature (25 ° C) of the test piece of Example 1 (secondary nitride material), the test piece of Example 2 (quaternary nitride material) and Comparative Example 1 (recrystallized material). 3 shows a displacement curve. From FIG. 4, it can be seen that both the secondary nitride material and the quaternary nitride material undergo sufficient plastic deformation, that is, exhibit high toughness at room temperature. In addition, the yield strength of both nitrides is about 1.5 times higher than that of recrystallized materials. This increase in yield strength is due to the superposition of the strengthening of dispersion of fine nitride particles and the strengthening of finer grains in the processed and recovered grain structure.
- Example 2 quadternary nitride material
- Comparative Example 1 recrystallized material
- the high-strength, high-toughness Mo alloy processed material of the present invention is used for semiconductors, ceramics, metal high-temperature firing support plates, high-temperature heating furnace heaters, high-temperature heating furnace members, and chemical equipment and equipment used in corrosive environments. It is useful for structural materials (including high-temperature incinerators, etc.) and supercritical / subcritical solution reactor materials.
