Development of technologies for the production of multi-component ligatures Al-Cu-B-C with high thermal characteristics

Abstract

The purpose of research is to provide a competitive alternative to aluminum silicon alloys used in automotive applications. This alternate can be created by developing composites of Al-5%Cu alloy reinforced with B4C particulates with a low coefficient of thermal expansion. Stir casting can be used to produce Al-5%Cu alloys containing different ratios of B4C. The squeeze casting technique decreased the porosity of the final material. The composites exhibited a fairly uniform particle distribution throughout the alloy matrix.
