【摘要】 采用真空浸渗法制备了ＭｇＬｉＡｌ／ＳｉＣ复合材料，系统研究了不同基体合金成分的ＭｇＬｉＡｌ／ＳｉＣ复合材料组织、性能及界面结构。研究结果表明，ＭｇＬｉＡｌ／ＳｉＣ复合材料界面结合良好，没有界面反应物。复合强化可明显提高ＭｇＬｉＡｌ合金的抗拉强度和弹性模量。更多还原

【Abstract】 Abstract MgLiAl/SiC composites have been produced by infiltration in vacuum. Study on microstructure and properties of MgLiAl/SiC composites has been carried out. The results showed a good combination between the matrix and SiC whisker. The tensile strength and modulus increased apparently by reinforcement of SiC whiskers, compared with that of the MgLiAl matrix.更多还原
