Densification behaviour, phase transformation, microstructural evolution and hardness values of microwave sintered Al–7Zn–2·5Mg–1Cu (7775) aluminum alloy were investigated and compared with conventionally sintered samples. Microwave sintering was performed in 2·45 GHz multimode microwave furnace at temperatures ranging from 570–630 °C. Microwave sintering at a heating rate of as high as 22°C/min resulted in ~55% reduction of processing time as compared to conventional sintering. A lower… CONTINUE READING
