摘要/Abstract

摘要： 采用拉伸试验机、光学显微镜、扫描电镜、X射线衍射仪和三维纳米X射线显微镜等分析手段研究了铁含量对铸态Al-Fe合金力学性能和微观组织结构的影响。结果表明:随着铁含量的增大,铸态Al-Fe合金抗拉强度和屈服强度增大,断后伸长率下降。大量的球状Al₆Fe析出相和杆状Al₃Fe析出相分布在试验合金铸锭晶界附近,与铸态Al-1.8Fe合金相比,铸态Al-2.6Fe合金具有更小尺寸的晶粒和更大尺寸的Al₃Fe析出相。尺寸更小的晶粒导致铸态Al-2.6Fe合金的强度高于铸态Al-1.8Fe合金,而铸态Al-2.6Fe合金伸长率更低的主要原因是具有更大尺寸的脆性Al₃Fe析出相。

Abstract: Effect of Fe content on mechanical properties and microstructure of as-cast Al-Fe alloy was studied by tensile testing machine, optical microscope, scanning electron microscopy, X-ray diffracter and three-dimensional nano-X-ray microscope. The results show that with the increase of Fe content, the tensile strength and yield strength of as-cast Al-Fe alloy increase, while the elongation decreases. A large number of spherical precipitates of Al₆Fe and rod-shaped precipitates of Al₃Fe are distributed near the grain boundary of the tested alloy ingots. Compared with the as-cast Al-1.8Fe alloy, the as-cast Al-2.6Fe alloy has finer grains and larger size precipitates of Al₃Fe. And the finer grains lead to the higher strength of as-cast Al-2.6Fe alloy than that of as-cast Al-1.8Fe alloy. The main reason for the lower elongation of as-cast Al-2.6Fe alloy is the larger size of brittle precipitate of Al₃Fe.
