Phase Transformations in the Al-Si Coating during the Austenitization Step

, 2011
Nowadays more and more hot stamped steel sheets dedicated for the automotive body-in-white structure are pre-coated to prevent the steel surface against iron oxidation and decarburization during the austenitization step.

Hot centrifugal coating: A novel method for enhancing diffusion bonding integrity at steel-brass interfaces

Results in Surfaces and Interfaces
Steel cylinders are widely used in industry, but their service life is often limited by corrosion and wear. Conventional coating methods generally produce only mechanical bonds and can lead to delamination and interfacial failure.

The Influence of Austenitization Conditions on Grain Growth and the Bending Performance of Boron Steel

During production of components using press hardening, the steel will at one point be heated to an austenitic state. Grain growth can occur during this austenitization if the time and temperature are sufficient, where the microstructure becomes ...

In Situ Techniques for the Investigation of the Kinetics of Austenitization of Supermartensitic Stainless Steel

, 2016
The austenitization and inter-critical annealing of X4CrNiMo16-5-1 (1.4418)supermartensitic stainless steel were investigated in-situ with synchrotron X-ray diffraction (XRD), dilatometry and differential scanning calorimetry (DSC) under isochronal ...

Revealing thickness-gradient microstructure and hardness evolution in a laser-treated 2.0 GPa ultra-high strength steel

Journal of Materials Research and Technology
Accurate control of local properties in laser-processed press-hardened steels (PHS) is hindered by steep through-thickness thermal gradients and the generate heterogeneous phase transformation paths.

Prediction of critical cooling rate under rapid heating rate and short holding time for pearlitic rail steel

Journal of Materials Research and Technology
Critical cooling rate (Vc) is typically employed to assess the ability of forming martensite for pearlitic railway steels. Currently, the examination of Vc is normally conducted by dilatometry analysis under a fully austenitizing condition.
