Al-Cu-Mn-Zr (ACMZ) is a new class of cast Aluminum alloys engineered to have exceptional microstructural stability up to 350 °C for automotive applications. These materials are expected to endure complex thermo-mechanical loading cycles throughout service. Mechanical property requirements such as strength, ductility and fatigue resistance vary with specific components in an automotive engine. This presentation will elaborate on the mechanical behavior of a series of ACMZ alloys with Cu content varying between 6.0 - 9.0 wt. %. Tensile, low cycle fatigue and creep properties will be discussed as a function of alloy composition and thermal history. The effects of grain boundary intermetallic particles and fine strengthening precipitates on tensile, low cycle fatigue and creep properties will be discussed.
