Optimizing the Aging Heat Treatment of Cast Aluminum Alloys
Cast aluminum alloys are used for many engine parts in today's cars. Many of the alloys used are age hardenable to get higher strengths. The optimum heat treatment used for producing the best combination of properties changes, as the cast part gets larger, due to changes in quench rate. In addition, parts are sometimes aged after casting (T5) without a separate solution step. In order to sort out all of the parameters that effects the resulting properties. Design of Experiments has been used to identify the most important parameters. In addition the quench sensitivity of A356 and B319 have been studied to determine the effect of quench rate and heat treatment on the optimization of properties. Results will be presented on the effect of these parameters on the strength of aluminum cast alloys.
