摘要:实验采用经过热挤压,热轧等方法制备的铝铁合金板材,通过 DSC、OM、SEM、XRD 分析和拉伸性能
测试,研究了不同固溶处理和时效处理对 Al-5%Fe 基合金 2mm 板材组织与性能的影响。实验结果表明,合
金适宜的固溶温度为 565~570℃,固溶时间为 80~100min,适当的提高固溶温度或延长固溶时间可使合
金中过剩相的溶解程度增大,即提高了合金的固溶程度,从而提高了板材强度,但过高的固溶温度或固溶
时间使合金的伸长率降低;合金适宜的时效温度为 180℃,时效时间为 6h,强度可达到 312MPa。热处理后
板材组织主要包括基体 Al、Mg2Si、Al2CuMg、Al23CuFe 和 Al2Fe3Si3 等相。

Abstract:The Al-Fe alloy plate were prepared using hot extrusion, rolling processes. The microstructures and
properties of Al-5Fe-Based alloy in different solutions and aging treatments were studied by tensile test, DSC,
OM, SEM and XRD analysis. The results show that the suitable solution temperature and time of alloy are 565~
570℃ and 80~100min, respectively. Increasing the temperature or extending the time of solution properly can
accelerate the solution of excess phase, which can raise the degree of solution of alloy and improve the stre
