Study on the Quenching Microstructure of Fe-0.36C-1.4B Alloy
The heat treatment microstructure of Fe-0.36C-1.4B alloy after austenitizing at 1000°C and water quenching then tempering at 200°C were studied by TEM and selected area diffraction. The results indicate that the alloy has typical microstructure of hypoeutectic cast iron because of boron addition. After quenching, the microstructure of the alloy was made up of martensite and B-containing carbide Fe23(C, B)6.
