摘要
以ZL101合金为基础,通过添加Cu、Ni、Mn、V、RE等合金元素,制备了改良ZL101合金,并对其高温力学性能进行了研究。结果表明,改良ZL101合金组织中由于出现了Al2Cu、Al7(FeMnSi)3、Al6Cu3Ni和AlxV3CuRE等新相,因而改善了合金的高温力学性能,提高了其服役温度,且改良合金制备工艺简单,成本低廉。
Modified Al-Si casting alloy was prepared by adding alloying elements,such as Cu,Ni,Mn,V,RE,and elevated mechanical properties of the alloy were analyzed.It is found that elevated mechanical properties of the alloy are improved as a result of creation of Al2Cu phase,Al7(FeMnSi)3 phase,Al6Cu3Ni and AlxV3CuRE phase in the microstructure,greatly raising the service temperature.In addition,the preparation technology exhibits the features of simple and low cost.
