Open publisher page 0 citations

Abstract

The properties and microstructure of SiCw/2024Al composite fabricated bypowder metallurgy technique were investigated.It is indicated that the properties of the compo-site can be tailor-made.Various mechanical and physical properties are obtained by adjustingSiC whisker content.The composite exhibits excellent elevated temperature and cryogenic prop-erties,and thermal stability.The phase of θ(Al_2Cu)precipitates at the interface between SiCwhisker and matrix,which may be unfavourable for mechanical properties.
