Localized Laser Heat Treatment on AISI 1045 Steel Using a LPBF Laser
A LPBF laser was used to locally heat‐treat the surface of normalized AISI 1045 steel bars. While sections of overheating were seen, adaptations of previously published energy density models were able to determine valid parameters to create a hardened martensitic surface.

Air‐hardening forging steels are a new steel concept, promising high strength and ductility combinations in combination with a reduced environmental impact. Herein, the effect of the microstructure before intercritical annealing is discussed in regard to microstructure evolution and strain hardening behavior.

Effect of Intercritical Heat Treatment on Mechanical Properties of Plain Carbon Dual Phase Steel
Mechanical properties of DP (Dual Phase) steels are greatly influenced by the microstructural features such as grain size, morphology and martensite volume fraction (Vm%).

Optimizing Advanced High‐Strength Steel Joints via Regional Rapid Cooling in Resistance Spot Welding
The study introduces a new methodology to control microstructural differentiations and internal stresses in martensitic steels’ heat‐affected zones during resistance spot welding (RSW). Utilizing a unique prototype setup based on the regional rapid cooling (RRC) process, the method optimizes material performance by narrowing the heat‐affected zone ...

Abstract The quenching and partitioning response of intercritically annealed steel with aluminum contents in the 2–3 wt.% range and a carbon content of 0.2 wt.% was studied. Two types of morphologies for retained austenite were observed in electron backscatter diffraction studies: blocky, untransformed austenite grains and partially transformed ...
