Abstract

By taking advantage of the positive effects of secondary precipitation, Commonwealth Scientific & Industrial Research Organization (CSIRO), has developed two competitive heat treatments (T6IX). The heat treatments are applicable to all age-hardening aluminum alloys and offer the potential to improve alloy properties and reduce processing costs. The aluminum heat treatment can be tailored for improvements in strength, ductility, toughness, and fatigue resistance, while the T6I4 process focusses on reducing the cost of heat treating. The ability to incorporate product-specific thermal treatments such as a paint-bake cycle, into these processes further demonstrates their flexibility.
