Table Typical Water Quenching Cooling Rates for Various Thicknesses of Aluminum Alloys Because of the rapid change in the quenching characteristics of water above 160 F, control of quenching speeds at various locations in a quench tank is difficult when using a
After quenching, aluminum alloys are aged, and during this process, a fine dispersion of elements and compounds are precipitated that significantly increase material strength. The diffusion process and precipitation kinetics vary with the alloy

The general types of heat treatments applied to aluminum and its alloys Preheating or homogenizing, to reduce chemical segregation of cast structures and to improve their Annealing, to soften strain-hardened (work-hardened) and heat treated alloy
Heat Treating of Aluminum Alloys HEAT TREATING in its broadest sense, refers to any of the heating and cooling operations that are performed for the pur- pose of changing the mechanical properties, the metallurgical structure, or the residual
