Sm对Mg-l0Y合金组织的细化作用
Effects of Sm on Microstructure Refinement of Mg-10Y Alloy
摘要
Abstract
Refinement of Mg24Y5 phase is a key for the further increase of mechanical properties of Mg 10Y alloy. The refinement effects of rare earth element Sm on Mg24Y5 phase and base microstructure were investigated. The results show that Sm addition improves the morphology of Mg24Y5 phase and promotes the formation of fine and dispersed Mg24 Y5 particles. Meanwhile, Sm addition further re fines the microstructure of base alloy by the effect of solid solution. The improvement of microstruc ture leads to the increase of mechanical properties at elevated temperature.关键词
