摘要: Composites of Zn-A1 alloys (ZA8 and ZA27) reinforced by fibres alumina, carbon or steel have been prepared squeeze casting. Microstructural observations reveal the segregation zinc-rich phase around fibres. The composites exhibit a greatly reduced creep rate in comparison with matrix alloys. thermal expansion coefficient is also significantly decreased. impact toughness has studied Charpy tests.
