Influence of Titanium on the Microstructure and Mechanical Properties of Foundry Zinc Alloy

Abstract

The article presents studies of the influence of titanium on the microstructure and mechanical properties of the zinc casting alloy ZL2. The positive effect of its addition on the strength of die castings made of this alloy was found. Castings with the addition of titanium had a fine structure and higher tensile strength (approx. 255 MPa for an alloy with Ti addition) compared to the base material (approx. 200 MPa). The addition of the modifier also increased the hardness of the obtained castings from 100 HBW (ZL2) to 130 HBW (alloy with the addition of Ti).
