Q1/ four specimen of the same 0.6% C, are heat treated differently as follows: 1- heated to 750°C for 30min and cooled in the furnace. 2-heated to 750°C for 30min and cooled in still air. 3-heated to 750°C for 30min and quenched in water. 4-heated to 750 °C for 30 min and quenched in brine water. 5-heated to 750 °C for 30 min and quenched in water and tempering at 250°C for one hour. Sketch the microstructure, and describe the mechanical properties?
