研究了Sn对轧制的Mg-8Li合金的显微组织、性能及织构的影响。结果表明,轧制可以细化合金的组织,同时使合金中析出的第二相更加弥散分布。Sn的加入可以提高合金的力学性能。其中,Mg-8Li-1Sn和Mg-8Li-3Sn合金轧制后的抗拉强度分别达到了141.35 MPa和181.59 MPa,断后伸长率达到26.1%和22.8%。合金中相织构为(0002)基面织构,相织构为(110)晶面织构,整体织构强度均较弱。 The effect of Sn on the microstructure, properties and texture of rolled Mg-8Li alloy was investigated. The results show that the rolling can refine the microstructure of the alloy and make the second phase precipitated more diffusely in the alloy. The addition of Sn can improve the mechanical properties of the alloy. Among them, the tensile strength of Mg-8Li-1Sn and Mg-8Li-3Sn alloy reached 141.35 MPa and 181.59 MPa respectively after rolling, and the elongation at break reached 26.1% and 22.8%. The phase texture of the alloy is (0002) basal texture, the texture is (110) crystal texture, and the overall texture strength is weak.
