“…In the hot stamping, the boundary heat transfer coefficient (BHTC) at the region I and III is larger than that at the region II due the higher pressure at the region I and III [22]. The heat flux from the part to the tools in the hot stamping can be described with Newton's law of cooling, ) ( c w T T H q (1) Where, q represents the heat flux, H represents the BHTC, T w represents the surface temperature of part, and T c represents the temperature of tool. According to Eq.…”

Abstract. In the paper, a typical part of B1500HS boron steel was formed using the hot stamping tools, and the effect of austenitization temperature on the microstructure and mechanical properties of B1500HS steel was studied by the experiment and finite element methods. The results show that, the temperature of steel plate has a significant effect on the temperature of hot stamping tools, and the temperature of punch rises at a faster speed than that of die in the hot stamping process. The austenitization temperature and time both have significant effects on the size of martensite, but have not obvious effects on the hardness. The cooling rate of steel plate has a significant effect on the tensile strength when the austenitization temperature is 870. The fracture of sample austenitized at 870 or 900 is the dimple, the fracture of sample austenitized at 930 or 960 is the mixture of quasicleavage and dimple.

“…But formability of AHSS or UHSS reduces remarkably with the enhancement of strength, and some defects, such as poor forming quality, cracking and spring-back, are easy to appear in the cold stamping. At present, lots of research about the hot stamping of quenchable boron steel has been done in the world, such as the investigation of high-strength steel forming technology [1], formability of quenchable boron steel in the hot stamping [2], design of hot stamping tools with cooling system [3], constitutive relationships of boron steel at high temperature [4] and numerical simulation of hot stamping process [5].…”

“…One of the possible ways is the usage of magnetic technologies such as induction heating and usage of magnetic field for material forming. According to [3] the induction heating allows to obtain high heating rates that necessary to avoid grain coarsening during heating process. This method was successfully approved in works of Bariani et.…”
