Title

Studying the Quench Sensitivity of Cast Al Alloys

Abstract

The quench rate sensitivity of A356 was measured by the Jominy end quench method. The results of hardness testing on sand cast A356 indicate that the microstructural inhomogeneity causes a large variation in hardness values. Results for an extruded 6061 alloys show that the smaller JEQ sample size could be used for wrought alloys, where the microstructure was inhomogeneous, with a reduced depression in the hardness. However, for cast alloys, the reduced hardness decrease was found to be detrimental to the results, due to the combination of higher noise in the data with the reduced data signal.
