Influence of Different Titanium Alloying Methods on the Microstructure and Wear Behavior of ZL108 Alloy
Two kinds of ZL108 alloys containing titanium are produced with electrolytic low-titanium aluminum alloy (named as ZL108D) and pure aluminum as well as Al-Ti master alloy (named as ZL108R) respectively. The influence of different titanium alloying methods on the microstructure and wear behavior is investigated. The result shows that it is an effective for grain refining of ZL108 alloy by adding titanium to the melt before casting. Addition of titanium can improve the wear resistance of ZL108 alloy, while ZL108D is superior to ZL108R. It is attributed to the addition with electrolytic low-titanium aluminum alloy results in better grain refinement.
