Data base construction on mechanical properties of thixoforged aluminum parts and their microstructure evaluation

Abstract

The purpose of this work is to construct the database on mechanical properties and microstructures of thixoforged hypereutectic and hypoeutectic aluminum parts. Mechanical properties of the semi-solid components can be improved by controlling process parameters such as solid fraction of the material, punch velocity, applied pressure, die temperature, and heat treatments condition, etc. In this study, the characteristics of the microstructures and mechanical properties of thixoforged 357, 319, and 390 Al alloy parts with an arbitrary shape were studied for variation of applied pressure (110, 140, and 170 MPa) and aging time (4, 6, and 10 h) followed by solution treatment.
