【摘要】 钪是优化铝合金性能最为有效的合金元素。添加钪会对铝及铝合金的组织与性能产生明显的影响。钪可以细化晶粒,抑制再结晶温度而且钪还是很好的强化剂。钪的加入对合金力学性能、焊接性能和耐蚀性能的提高具有重要的影响。更多还原

【Abstract】 Scandium was the most effective alloying element to optimize the property of aluminum alloy.The obvious in- fluence of adding a little Scandium on structure and properties of Aluminum alloy.The scandium could refine crystal grains of Alloy,the restraint recrystallization temperature and the scandium were still a very good strengthening agent. The important effect of adding Scandium on improving mechanical property,welding property and corrosion resistance of alloys.更多还原
