چکیده انگلیسی
The effect of heating rate on liquid metal embrittlement (LME) of a galvanized twinning induced plasticity (TWIP) steel was investigated by hot tensile testing. The specimens were heated with different heating rates to 600, 700 and 800â¯Â°C, and elongated to 40%. During the hot tensile tests, various Fe-Zn intermetallic compounds were formed depending on the heating rate and the deformation temperature, and they were distinguished by X-ray diffraction and energy dispersive spectroscopy. δ and Î were observed in the coating after 600â¯Â°C deformation regardless of heating rate. Since both phases did not liquefy at 600â¯Â°C, the steel was not embrittled. Heating to 700â¯Â°C sometimes produced δ which would be liquid at 700â¯Â°C. It was only produced at the highest heating rate and embrittled the steel. Î was produced at 800â¯Â°C regardless of heating rate. Hence, the steel suffered from LME in all heating rate condition. Based on the results, the importance of selecting temperature and heating rate to study LME by hot deformation testing is discussed.
