three kinds of titanium alloying methods include that low-titanium aluminum produced by electrolysis

aluminum-titanium master alloys and villiaumite were chosen. The influence of titanium alloying methods on the microstructure and wear behavior of Zn-Al alloy was studied. The test results show that it is an effective for grain refining of Zn-Al alloy by adding titanium to the melt before casting. The addition of titanium by electrolysis is the most effective for grain refining of the Zn-Al alloy. The reson can be attributed to the titanium atoms evenly spread to the whole melt rapidly under stirring action of electromagnetic field and

the better capacity of heterogeneous nucleation of in-situ precipitating heterogeneous nucleation sites. The finer grain size increases the grain boundary areas and it causes that the grain boundary has better ability of prohibit dislocation passing through. Thus

the binding ability of the base is strengthened. The test alloy containing titanium by electrolysis showed the highest wear resistance.
