研究了不同锻压变形量下轻量化机床用新型铝合金的显微组织与力学性能。结果表明,随着锻压变形量从0增加至14%,新型铝合金的抗拉强度和屈服强度先增加然后基本不变,断后伸长率和冲击韧性则先增加后减小。锻压变形量优选为12%;与未进行锻压的试样相比,锻压变形量为12%时新型铝合金的抗拉强度、屈服强度、断后伸长率和冲击韧性分别增加了28.5%、32.6%、77.6%和73.8%。
The microstructure and mechanical properties of a new type of aluminum alloy for the light weight machine tools under different forging deformation were studied. The results show that with the increase of forging deformation from 0 to 14%, the tensile strength and yield strength of the new aluminum alloy increase first and then remain unchanged, while the elongation and impact toughness of the new aluminum alloy first increase and then decrease. Forging deformation is preferably 12%; compared with the sample without forging, the tensile strength, yield strength, elongation at break and impact toughness of the new aluminum alloy increased by 28.5%, 32.6%, 32.6% respectively when the amount of forging deformation was 12% %, 77.6% and 73.8%.
