HWTS 50 Tool Steel Tailored for Laser Powder Bed Fusion: Sliding Wear of Bare Surfaces and Nitriding Response in Comparison with 18Ni300 and AISI H13

steel research international, Volume 97, Issue 10, Page 5103-5114, October 2026.
This work investigates the wear resistance and nitriding behavior of PBF‐LB/M‐processed Osprey HWTS 50, a lean hot work tool steel. Three heat treatment conditions are compared to conventional wrought H13, H11, and PBF‐LB/M 18Ni300. The study highlights HWTS 50's enhanced nitrogen diffusion, deeper nitriding hardness depth, and comparable or improved ...

Some Aspects of Bainite Transformation in Fe-Based Alloys

, 1995
The mechanism of the bainite transformation in carbon containing steels was discussed after presenting our recent experimental results ; (1) the bainite transformation has its own C-curve, (2) incomplete phenomenon is a general feature of the bainite ...

Karl Popper and the Mechanisms of Hydrogen Embrittlement

Advanced Engineering Materials, Volume 28, Issue 17, 9 September 2026.
Representation of the beginning of loss of ductility rather than embrittlement. Small concentrations of hydrogen in a diffusible form within iron are well‐established to harm the mechanical integrity of steels. There are theories that attempt to explain the pernicious role of hydrogen.

New model for the overall transformation kinetics of bainite. Part 2: Validation [PDF]

, 2006
A new model for the overall kinetics of the bainite transformation has been validated experimentally. The new model, presented in the 1st part of this work, is based in the displacive mechanism for bainite transformation. Thus, the bainite transformation

Effect of the cooling rate in the medium temperature zone on the phase transformation and microstructure of carbide-free bainitic steel

Journal of Materials Research and Technology
Controlling continuous cooling is considered an effective means of producing high-strength and high-toughness bainitic steel. A medium carbon bainite frog steel is designed.

Essential work of fracture and absorbed energy by Charpy impact test of TRIP780 1.5 mm thick sheet steel Kerbschlagarbeit und absorbierte Energie bei der Charpy‐Schlagprüfung an 1,5 mm dickem Restaustenitstahlblech (HCT 780)

Materialwissenschaft und Werkstofftechnik, Volume 57, Issue 9, Page 895-907, September 2026.
The study demonstrated that absorbed energy (Charpy impact test) and fracture toughness (EWF test) are essential for evaluating the mechanical performance of thin sheet metallic materials. Transformation‐induced plasticity (TRIP) steels have been extensively studied concerning their mechanical performance under monotonic loading and conventional ...
