摘要

研究了不同时效处理温度及时间对Al-5Fe合金组织和性能的影响。结果表明

时效处理对Al-5Fe合金组织和性能有显著的影响;时效时间较短时

强化相析出不充分

合金性能较低;随着时效时间延长

强化相逐渐析出

但时效时间过长时

强化相颗粒较粗大

使得合金性能较差;当时效温度为180℃

时效时间为6h时

合金的抗拉强度、和伸长率分别为312MPa和3.8%。

Abstract

Effects of different aging temperatures and time on the microstructure and mechanical properties of Al-5Fe based alloy were investigated.The results show that the aging treatment has a significant effect on microstructure and properties of the Al-5Fe alloy.The precipitation of strengthening phase is inadequate with a short aging time

which results in a lower performance

while with increasing aging time

the strengthening phase is precipitated gradually.However

with the aging time more than 6h

strengthening phase particles are coasened

leading to the decrease of mechanical properties of the alloy.Under the experimental conditions

the tensile strength

yield strength and elongation reach 312MPa

300MPa and 3.8%

respectively

with aging temperature of 180℃for 6h.
