Abstract

Remanufacturing quality is critical to the service performance of aluminum alloy castings. Here, casted A356 Al7Si0.3 Mg alloy was remanufactured by using ultrasonic frequency pulsed (UFP) TIG deposition process. The heterogeneous microstructure evolution, hardness distribution, and tensile behavior of the repaired part were investigated and discussed. The UTS, YS and elongation of the UFP-TIG remanufactured A356 are 183 MPa, 121 MPa and 3.3 %, respectively. The repaired part shows a strength coefficient of 0.93 and superior ductility over the cast.
