Abstract

Cast aluminum alloys, particularly 319-type, are increasingly being utilized by the automotive industry for manufacturing engine blocks and cylinder heads to reduce vehicle weight and consequently increase fuel economy and reduce emissions. These engine blocks and cylinder heads are often heat treated after casting to impart increased mechanical strength via precipitation hardening. When aged for peak strength, a 319-type aluminum alloy casting will develop a macroscopic, irreversible dimensional change, termed thermal growth, during extended high-temperature exposure. This paper describes the simulation of microstructural evolution during casting and subsequent heat treatment processes and thermal growth during high-temperature service of an engine block. The prediction can be used to design and optimize heat treatment time and temperature to obtain a stable casting component.
