Definitions
- the present invention relates to a high-strength, wear-resistant aluminum alloy extruded material having both excellent machinability in machine processing and caulking as toughness.
- the Japanese Industrial Standards specify various aluminum alloy materials.
- the 400-thread alloy can obtain relatively high wear resistance by adding Si to aluminum and dispersing and precipitating hard Si particles in the metal structure.
- S ⁇ particles have the effect of dispersing chips, but are one of the factors that deteriorate the surface roughness of the cut surface.
- ABS body parts For example, in the case of automotive anti-lock brake system actuator pod parts (hereinafter referred to as ABS body parts), parts of cylinders containing pistons and valve parts, hydraulic circuit grooves, etc. are cut. After the parts are assembled, a caulking seal is applied.
- An object of the present invention is to provide an aluminum alloy extruded material that is effective for improving both the strength, wear resistance, cutting property, and caulking quality, which are considered to have a negative correlation with each other. I do.
- the Si component is obtained by precipitation of Mg 2 Si with the Mg component to obtain the strength by age hardening and to secure the wear resistance due to the Si particles.
- Mg 0.1 to 0.45%.
- M g and 0.3 to 0.4 may to control 5% range, from 0.3 to 0 to M g ideally. 4 (except 0.4) It is better to control to%.
- the range of the Mg component is controlled to be narrow in this way, the strength of the extruded material can be stabilized to a relatively high strength, and the control of S ⁇ particles, which contribute to wear resistance, is reduced. "! ⁇ 5.1% control the wear resistance.
- Mg in terms of strength, Mg must be at least 0.1%, and as described above, 0.3% or more is good, but caulking (stickiness) is ensured. To achieve this, Mg should be 0.45% or less, ideally less than 0.40 / 0.
- the 1 ⁇ 18 component is suppressed to 0.45% or less, so if the strength is slightly insufficient for the material requirements, the effect of adding Cu can be expected.
- Cu is added in a large amount, it may cause potential difference corrosion. Therefore, it is preferable to control Cu in the range of 0.10 to 0.20%.
- M ⁇ has an effect of making crystal grains of the extruded material fine, it is preferable to add 0.01 to 0.5% from the viewpoint of improving machinability.
- ⁇ ⁇ may become one of the causes of potential difference corrosion if it precipitates at the grain boundaries, and it reduces caulking, so ⁇ ⁇ is ideally between 0.05% and 0.15%. It is good to control to the range.
- the Fe component is controlled.
- the Fe component is generally regarded as an impurity.
- the effect of crystal grain refinement has been confirmed.
- the Fe particles are dispersed in the crystal grain boundaries, and the chips that have been thinly cut at the time of cutting are liable to break from the Fe particles as starting points, thereby improving the machinability.
- Cr has a crystal grain refining effect, and is added as necessary.However, if it exceeds 0.5%, a large primary crystal product may be generated, and the caulking property is reduced. It is better to control to 0.01 to 0.5%.
- Ding i also has the effect of refining the crystal grains, and a small amount improves the machinability. However, the content is controlled within the range of 0.01% to 0.1% when adding it to shorten the life of cutting tools exceeding 0.1%.
- FIG. 1 (Table 1) shows the aluminum alloy components of the extruded material according to the present invention and the comparative extruded material, with the balance being aluminum and unavoidable impurities.
- Figure 2 shows the artificial aging conditions and mechanical properties of the extruded material.
- Figure 3 shows the results of evaluation of the extruded material for cutting and caulking.
- Figure 4 shows the relationship between the upsetting ratio ⁇ and the constraint coefficient f.
- the homogenization treatment was performed at 0 to 590 ° C for 6 hours or more.
- the billet was preheated to 450 to 50 ° C. to extrude a rectangular extruded material of about 35 mm ⁇ 80 mm.
- solution heat treatment and artificial aging treatment are performed.
- the solution heat treatment may be repeated after extrusion, heating and quenching may be performed, but in this embodiment, it is quenched immediately after extrusion in the vicinity of the extrusion die. It was put in and tempered to a predetermined artificial aging.
- the artificial aging conditions are shown in Figure 2 (Table 2), and the unit of temperature in the column of aging is ° C.
- the extruded material of NO.1 has been subjected to artificial aging treatment at 185 ° C for 4 hours, and the state of the aging treatment means the state showing almost the highest tensile resilience of the material.
- the term “stable” is used, the term “sub-aged” means that the heat treatment is stopped before reaching the original maximum tensile strength of the material, and the term “overage” refers to the original maximum tensile strength of the material. It means that the heat treatment has been performed up to the state where it is slightly exceeded.
- Table 2 shows the measurement results of the tensile strength in the extrusion direction, 0.2% strength, and the Rockwell B scale (HRB) hardness of the surface of the extruded material.
- Table 2 shows the “elongation” in the extrusion direction
- Table 3 shows the critical upsetting ratio and the average deformation resistance as evaluations of the caulking property (stickiness).
- the critical upsetting ratio is defined as: A test piece with a diameter of 14 mm and a height of 21 mm is sampled in the extrusion direction of the extruded section, and this is cold-set up in the axial direction and pressed to the side. This refers to the upsetting rate at which micro-cracks begin to occur.
- the critical upsetting ratio was determined by the following equation.
- ⁇ hc h 0- h c / h 0 x 1 0 0
- the test conditions were room temperature, a compression rate of 1 Omm / s, and an autograph of a 25 ton test machine was used.
- the average deformation resistance value is the deformation resistance value of the material when cracks occur on the side surface of the test piece, and was calculated by the following equation.
- machinability is shown in Fig. 3 (Table 3) as “Maximum chip length” and “Total chip length”.
- the maximum chip length refers to the maximum chip length among the chips generated under the following test conditions
- the total long chip length refers to the total length of the generated long chips.
- Cutting tool 04.2X06.8 with 8 steps Drill, number of revolutions: 1200 rpm, feed: 0.05 mm / rev
- Processing amount 15 mm, Number of processing holes: 3 holes, Cutting oil: Used
- the extruded materials 1, 2, and 3 were obtained by increasing the Fe component to 0.38%, 0.68%, 0.92%, and the extruded material for comparison 15 (Fe: 0 Extruded material 15 has a good elongation of 9.4% compared to .29%), 16 (Fe: 1.20%) and 17 (Fe: 1.50%).
- the chip length is long and the cutting performance is poor.
- Extruded materials 16 and 17 have short chip length and good machinability, but have poor elongation of 0.2% and 5.4%.
- extruded materials 16 and 17 also have lower marginal upsetting rates.
- extruded materials 1 and 2 are compared, there is a small difference in elongation and critical upsetting ratio, especially in average deformation resistance, but there is a difference in chip length, and Fe is greater than 0.38% for crimpability. It suggests that the cutting performance can be improved while ensuring the cutting performance.
- Extruded materials 4 to 10 focusing on the amount of change in the Fe component and the amount of change in the Mg component, the caulking properties (elongation, critical upsetting rate, average deformation resistance) and cutting properties (maximum chip length, Extruded materials 7, 8, 9, and 10 have the same Mg content as 0.39 ⁇ / ⁇ , and the Fe content has increased by about 0.05% each. However, there is almost no difference in tensile strength and critical upsetting ratio, and the machinability is improved. Comparing extruded materials 4, 5, and 6 shows that the 6 component is almost the same as about 0.5%,
- the Mg content has increased to 0.31%, 0.35%, and 0.44%, and the tensile strength and proof stress have been improved with almost no effect on the chip length and critical upsetting ratio. I have.
- Mg should be in the range of 0.3 to 0.45% and Fe should be in the range of 0.40 to 0.90% in order to ensure stable strength and improve machinability and caulking. I understand.
- the Mg should be 0.3% or more to less than 0.4%, and the Fe should exceed 0.5% to 0.5%. Ideally, it should be controlled to 90 o / o or less.
- Extruded materials 11 and 12 and extruded materials 13 and 14 compare the effects of age hardening.
- the limit upsetting ratio and average deformation resistance are almost the same, that is, the chip length can be shortened without sacrificing the caulking property, and the machinability is improved. ing.
- overaging conditions shown in Table 2 were performed at a high tempering temperature, it goes without saying that overaging may be performed by increasing the heat treatment time. Since the extruded materials 1 to 12 were controlled so that the Si component was in the range of 3.0 to 6.00 and still in the range of 4.1 to 5.1%, the evaluation results were omitted. The wear resistance was stable.
- Mn component in the range of 0.05% to 0.15% also contributes to the improvement of machinability.
- extruded material according to the present invention makes it possible to achieve both abrasion resistance, strength, hardness, and caulking properties (stickiness), which have been conventionally contradictory to these properties, as compared with conventional abrasion resistant materials. Not only is it excellent in machinability, it can be used as an aluminum alloy extruded material for products requiring high pressure resistance, caulking and machinability.
