Effect of Ti Addition on Mechanical Properties of High Pressure Die Cast Al-Mg-Si Alloys

Abstract:

Titanium significantly improves the mechanical properties, especially the ductility of a diecast Al5Mg1.5Si0.6Mn alloy. When a titanium addition of 0.20 wt.% is made the elongation in the as-cast condition is increased from 11% to 18% and the yield strength is increased from 136 MPa to 157 MPa and the ultimate tensile strength from 296 MPa to 308 MPa. The improved mechanical performance can be attributed to the reduced tendency for hot tearing due to Ti addition.
