摘要
Abstract
Heat-resistant cast aluminum alloys have been widely applied in the field of high temperature and high stress such as the cylinder head of diesel engines.With an increase in the power of engines and fuel-economics,demand for high-temperature resistance and fatigue-resistance is more and more urgent.This contribution starts from the review of conventional strengthening phases utilized in the design for a heat-resistant cast aluminum alloy.Then the criteria for heat-resistant precipitates design and newly recognized heat-resistant phase structure are summarized,followed by a brief introduction of the newly developed aluminum based eutectic alloys for elevated temperature applications.In combination with some advanced heat-resistant aluminum cast alloys which have found applications,perspective of the future development of heat-resistant cast aluminum alloys is carried out.关键词
