Title of Poster presented:

Application of Jominy End Quench Approach for the Development of Quench Factor Analysis and Microstructure Prediction of Cast Al-Si-Mg Alloys.

Abstract:

The mechanical properties of age-hardenable Al-Si-Mg alloys, to a large extent, depend on the rate at which the alloy is cooled after the solutionizing treatment. Quench factor analysis was developed to describe the relationship between cooling rate and final mechanical properties of the age-hardenable materials. This analysis assumes the precipitation kinetics of aluminum alloys during continuous cooling is additive and can be described by the classical nucleation and growth of the secondary phase. This method has been used to successfully predict yield strength, hardness of wrought aluminum alloys. However, the quench factor data for aluminum castings is still rare in the literature. In this study, the Jominy end quench approach is used to develop Time-Temperature-Property curves for quench factor analysis of cast aluminum alloy A356. The results are discussed based on the precipitation kinetics and microstructure as a function of cooling rate along the length of the bar.
