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 ...

Hot Press Forming of Tailor Welded Blank: Experiments and FE Modeling
ISIJ International, 2012 Hot Press Forming (HPF) of Tailor Welded Blank (TWB) was investigated with particular focus on the formability and phase transformation of the constituent base materials. Dilatometric analyses were conducted to study strength differentials for various cooling rates after heat treatment. U-draw bending tests were performed to evaluate the influence of a

Dual-phase hot-press forming alloy [PDF]
Materials Science and Engineering: A, 2010 Hot-press forming steels are formed in a fully austenitic state followed by die-quenching in order to generate martensite and achieve strong steel. The ductility however, tends to be limited. We explore in this work a novel steel design in which the forming operation is in the two-phase austenite and ferrite field, so that the quenching results in a ...

Interpretation of surficial shear crack propagation mechanisms in bending for Zn or AlSi coated hot press forming steels [PDF]
Scientific Reports, 2021 The bending angle at the peak load is regarded as the most important parameter for evaluating bending properties of hot-press-forming (HPF) steels. However, it is not a mechanics-based parameter for the bending criterion, and the data interpretation is ...

Flow characteristics of aluminum coated boron steel in hot press forming
Transactions of Nonferrous Metals Society of China, 2009 Abstract The flow characteristics of aluminum coated boron steel in hot press forming were investigated. Furthermore, the effects of aluminum coated layer on press forming were analyzed during deep drawing. The results show that aluminum coated boron steel exhibits a high sensitivity on temperature and strain rate.
