【摘要】：對(duì)Mg-4Li和Mg-6Li合金進(jìn)行熱擠壓處理后,在不同溫度下進(jìn)行退火,研究退火工藝對(duì)合金顯微組織與性能的影響。結(jié)果表明:經(jīng)290℃熱擠壓后,Mg-4Li合金中α相產(chǎn)生了局部再結(jié)晶,而Mg-6Li合金中的β相優(yōu)先于α相基本完成再結(jié)晶。與Mg-4Li合金相比,由于β相的存在,Mg-6Li合金完全再結(jié)晶的退火溫度可降低至200℃,并且擠壓及退火態(tài)Mg-6Li合金的硬度也降低。
[Abstract]:Mg-4Li and Mg-6Li alloys were hot-extruded and annealed at different temperatures. The effect of annealing process on microstructure and properties of the alloys was studied. The results show that local recrystallization occurs in 偽 phase of Mg-4Li alloy after hot extrusion at 290 鈩，
