in this study, gtaw process and cored wires were used to coat al/al3ti wear resistant composite on a commercial pure al substrate. wire drawing process was utilized to produce the cored wires from aluminum strips and a mixture of titanium and aluminum powders. the microstructures and the present phases were investigated by metallographic, sem equipped with eds and xrd analysis. moreover, the ha...

Superheater is one of the boiler components that works to heat saturated steam coming out drum, by utilizing hot gases from combustion. In this study using Gas Tungsten Arc Welding (GTAW) and SA-213 grade T91 T22, these two materials require Post Weld Heat Treatment (PWHT). One crucial factors in PWHT holding time, because time aims obtain a homogeneous temperature microstructure can affect mec...
