由于Al-Li合金具有低密度和高弹性模量,所以在航天航空应用中给予极大的重视。快速凝固 Al-Li 合金与常规工艺方法获得的熔铸法相比有许多优点,例如减少了合金的偏析,扩大了固溶的范围。该工艺能使合金具有最佳的性能,并且不需要后面的成形工序及机加工就可以获得适 Due to the low density and high modulus of elasticity of Al-Li alloys, great attention has been given to aerospace applications. The rapid solidification of Al-Li alloys offers many advantages over the cast-in-place method obtained by the conventional process, such as reducing the segregation of the alloy and broadening the range of solid solution. The process can make the alloy with the best performance, and do not need the back of the forming process and machining can be obtained suitable
