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 ...

An overview of high thermal conductive hot press forming die material development [PDF]
Journal of Mechanical Engineering and Sciences, 2015 Most of the automotive industries are using high strength steel components, which are produced via hot press forming process. This process requires die material with high thermal conductivity that increases cooling rate during simultaneous quenching and ...

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 ...

Die Material Selection Criteria for Aluminum Hot Stamping
Journal of Manufacturing and Materials Processing, 2021 The aim of this work is to develop a die material selection criterion for aluminum hot stamping applications. The criterion has been based on the back-to-back comparison of a set of reciprocating friction and wear tests.
