摘要
主要研究了机械振动铸造过程中不同的振动频率和振幅对A356铝合金的微观组织和力学性能的影响。结果表明:试样的晶粒尺寸大小、抗拉强度和伸长率随着振动频率和振幅的增加先升高后降低;当振动频率为30 Hz、幅度为0.6 mm时,A356铝合金试样的综合力学性能最好。
The effects of different vibration frequencies and amplitudes on the microstructure and mechanical properties of A356 aluminum alloy during mechanical vibration casting were studied. The results show that the grain size, tensile strength and elongation increase first and then decrease with the increase of vibration frequency and amplitude. When the vibration frequency is 30 Hz and the amplitude is 0.6 mm, the comprehensive mechanical properties of A356 aluminum alloy specimen are the best.
