Influence of Heat Treatment and Scan Rotation on the Microstructure of Hot Work Tool Steel Manufactured using Laser Powder Bed Fusion

steel research international, EarlyView.
The study investigates the influence of heat treatment and scan rotation on the microstructure of a modified H13 tool steel manufactured using laser powder bed fusion. Key findings include the refinement of prior austenite grains (PAGs) due to recrystallization and carbide pinning, and the significant impact of scan rotation on the size distribution of

Additive Manufacturing of Hot‐Work Tool Steel by In Situ Alloying Using Laser Powder Bed Fusion and Directed Energy Deposition—Strategies to Improve Chemical Homogeneity

steel research international, EarlyView.
To support future alloy development a powder mixture is processed by laser additive manufacturing. The powder mixture containing Mo‐ and W‐rich tracers is processed by powder bed fusion using single and double laser exposure and by directed energy deposition which provides drastically enlarged melt pools.

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, EarlyView.
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 ...

Two‐Stage Isothermal Transformation of Austenite into Nanobainite in a Chemically Inhomogeneous Medium‐Alloy Steel Containing 0.5 wt% C

steel research international, EarlyView.
The effect of chemical inhomogeneity on the microstructure and properties of nanobainitic steel is investigated. A two‐stage isothermal heat treatment that produced a more uniform microstructure is designed. The first‐stage temperature is higher than the MS of depleted bands; conversely, the second‐stage temperature is lower than the first‐stage ...
