Coating Degradation in Hot Press Forming
ISIJ International, 2010 The thermo-mechanically induced microstructure changes occurring in a type 1 aluminized coating on hot press forming (HPF) steel were studied in detail. The formation of intermetallic phases at the soaking temperature prior to die quenching revealed that the coating matrix consists mainly of FeAl2 intermetallic phase by the time the press forming ...

Parameter Measurement and Conductive Heating During Press Hardening by Hot Metal Gas Forming [PDF]
IOP Conference Series: Materials Science and Engineering, 2019 Abstract Press hardening of steels for the production of car body components is very common. The reason for this is that the process allows the use of blanks with low wall thickness and the production of ultra-high strength components with complex geometries.
