摘要
研究了在A1-2 2 %Si合金中分别加入较高量的锰和铁对Al -2 2 %Si合金室温和高温抗拉强度的影响。结果证明 ,加入 0 99%Fe、0 76 %Mn后 ,合金的室温抗拉强度值略有降低 ,30 0℃和 40 0℃的抗拉强度值有较大幅度的提高 ;加入 0 99%Fe、1 5 0 %Mn后 ,30 0℃和 40
An investigation was carried out into the tensile strength of an Al-22%Si alloy with the elevated content of iron and manganese.The results indicated that the tensile strength of the alloy at the room temperature decreased with the elevated content of iron and manganese while the tensile strength of the alloy increased at 300 ℃ and 400 ℃
