【摘要】：鎂合金組織對(duì)其力學(xué)性能影響十分顯著,通常未經(jīng)處理的合金組織中存在的粗大相嚴(yán)重割裂基體,降低力學(xué)性能,惡化其切削加工性能,制約高強(qiáng)鎂合金的廣泛應(yīng)用。鑒于此,從鎂合金的組織細(xì)化方面入手,概述了變質(zhì)處理技術(shù)、機(jī)械攪拌半固態(tài)和定向凝固技術(shù)在高強(qiáng)鎂合金組織細(xì)化及其對(duì)力學(xué)性能影響方面的研究現(xiàn)狀。最后對(duì)鎂合金組織細(xì)化前景進(jìn)行了展望,對(duì)推廣鎂合金的應(yīng)用具有一定參考意義。
[Abstract]:The microstructure of magnesium alloy has a significant influence on its mechanical properties. Generally, the coarse phase in the untreated alloy structure seriously cuts the matrix, reduces the mechanical properties, deteriorates its cutting performance, and restricts the wide application of high-strength magnesium alloy. In view of this, from the aspect of microstructure refinement of magnesium alloy, the research status of metamorphic treatment technology, mechanical mixing semi-solid state and directional solidification technology on microstructure refinement of high-strength magnesium alloy and its influence on mechanical properties are summarized. Finally錛，
