Al-Zr-Cr-La多元弥散相对Al-Mg合金的强化作用

The Strengthening Effect of Al-Zr-Cr-La Dispersoid to Al-Mg Alloy

摘要:

研究了Al-Zr-Cr-La多元弥散相对Al-Mg合金的强化作用。结果表明，在Al-Mg合金中，同时添加Cr和La与同时添加Zr、Cr和La均可提高合金的硬度、强度并抑制合金的再结晶；与同时加入Cr和La相比，同时添加Zr、Cr和La可更有效地抑制合金的再结晶，对合金的硬度、强度的提高幅度也较大

Abstract:

The strengthening effects of Al-Zr-Cr-La dispersoids to Al-Mg alloys have investigated. The results show that adding Cr and La and adding Zr, Cr and La at tha same time can improve the hardness and strength and the capability to inhibit the recrystalization for the Al-Mg alloys. Comparing wih adding Cr and La, adding Zr, Cr and La at the same time has more obvious effect to inhibit the recrystalization and increase their hardness and strength
