A thin piece of 0.3mm thick hot-rolled strip of 1080 steel is heat-treated in the following way. Use the IT diagram for steel and other Knowledge to determine the microstructure of the steel sample after the heat treatment. Heat Treatment: Heat for 1 hour at 860 degree C; cool in a molten salt bath at 350 degree C and keep it in the bath for 1 hour then cool it in air, this results in a microstructure and the name of the heat treatment is

Solution

the result of the micro structure is bainite

the name of this heat treatment : austempering
