快速凝固铝铁、铝锰合金在加硅对机械性能的影响日本进行了快速凝固粉末冶金法制取Ａｌ－Ｆｅ、Ａｌ－Ｍｎ合金时添加硅的研究。研究表明，加有１５％硅的Ａｌ－Ｆｅ合金的室温抗拉强度明显提高。而添加１５％硅的Ａｌ－Ｍｎ合金的室温抗拉强度与不加硅的几乎相同，总的说... Rapid solidification of aluminum and aluminum, aluminum-manganese alloy in the silicon on the mechanical properties of Japanese rapid solidification powder metallurgy method Al-Fe, Al-Mn alloy added silicon. The results show that the room temperature tensile strength of Al-Fe alloy with 15% silicon increases obviously. However, the tensile strength at room temperature of Al-Mn alloy with 15% silicon addition is almost the same as that without silicon addition.
