Alloy Optimization for Reducing Delayed Fracture Sensitivity of 2000 MPa Press Hardening Steel

open access: yesMetals, 2020
Press hardening steel (PHS) is widely applied in current automotive body design. The trend of using PHS grades with strengths above 1500 MPa raises concerns about sensitivity to hydrogen embrittlement.

Q&P PROCESS IN PRESS-HARDENING OF 42SICR STEEL

open access: yesActa Metallurgica Slovaca, 2018
One of today’s advanced heat treatment routes for high-strength steels is the Q&P process which delivers high ultimate strengths combined with good ductility. The resulting microstructure is a combination of martensite and small fractions of bainite and retained austenite. Retained austenite has the form of thin needles adjacent to martensite laths.

A Better Understanding of Hydrogen Trapping and Diffusion in Aluminized Press-Hardenable Steels

open access: yesJournal of Materials Research and Technology, 2023
Press hardenable steels (PHS) coated with Al–Si alloy are widely used in the automotive industry owing to their good mechanical properties (Yield Strength >1200 MPa and Tensile Strength >1500 MPa). The presence of Al–Si coating prevents oxidation and decarburization of steel during austenitization.
