In the spot weld of TRIP1100 steel, the HAZ is divided into three subzones from a metallurgical viewpoint: uppercritical (UCHAZ), inter-critical (ICHAZ), and sub-critical HAZ (SCHAZ).
The SEM micrograph showing the HAZ subzones of TRIP steel spot weld is presented in Figure 5a indicating the tempering of the martensite in SCHAZ and ICHAZ [15].
Meanwhile, because the HAZ along fusion line of steel pipe is very narrow, the sample of HAZ for the impact test may include other zones such as fine grain HAZ (FGHAZ), intercritical HAZ (ICHAZ), and even base metal (BM), which may affect the impact energy of HAZ of steel pipe.
