摘　　要：采用喷射沉积坯轧制和ＲＳ／ＰＭ粉末挤压坯轧制的２种工艺制各了Ａｌ－８．５Ｆｅ－１．３Ｖ－１．７Ｓｉ和Ａｌ－８．５Ｆｅ－１．３Ｗ－１．７Ｓｉ合金的板材，并通过透射电镜，扫描电镜和力学拉伸实验研究了板材的组织性能．结果表明，综合性能ＡｌＦｅＷＳｉ合金优于ＡｌＦｅＶＳｉ合金的喷射沉积坯轧制板材．The plates of both Al-8.5Fe-1.3V-1.7Si and Al-8.5Fe-1. 3W-1.7Si alloys were prepared by both spray deposition-rolling and rapid solidification-powder metallurgy-rolling processings, and their microstructure and properties by means of TEM, SEM and tensile testing. The results show that the AlFeWSi alloy has better mechanical properties than the AlFeVSi alloy; the plates produced by the spray deposition-rolling processing have high plasticity. Therefore, an AlFeWSi plate with good mechanical properties is likely to be acquired by spray deposition-rolling processing.
