Effect of Prior Austenite Grain Size on the Hydrogen Diffusion Behavior in 30MnB5 Steel

Materials
In this study, we investigated the effect of heat treatment-induced grain size on the hydrogen embrittlement (HE) resistance of 30MnB5 steel, focusing particularly on the variation in prior austenite grain (PAG) size. As the heat treatment time increased, the PAGs coarsened, leading the martensite packets, blocks, and lath sizes to also coarsen. As the

In Situ Alloying of H13 Tool Steel With TiC via PBF‐LB/M

steel research international, EarlyView.
H13 tool steel is in situ alloyed with titanium carbides (TiC) in amounts up to 30 wt.%. This approach offers the advantage that the carbides melt only partially during processing, preventing excessive carbon enrichment of the steel matrix. The resulting microstructure consists of coarse, undissolved and fine, reprecipitated carbides, leading to grain ...

Exploiting Residual Elements Arising from Scrap Steel in Future Sustainable Steel Alloy Design

steel research international, EarlyView.
Herein, the effects of residual elements Cu and Sn on grain growth, recrystallization, and phase transformation in C–Mn steel are summarized, and a case study is presented on how the presence of residual elements can be exploited to reduce deliberate Nb microalloying while achieving the same grain size control and strength during thermomechanical ...

Austenite reconstruction via EBSD measurements: a tool to understand low Carbon martensite steel properties

MATEC Web of Conferences, 2015
The basic characterization of the austenite grain size and shape prior to quenching to martensite was already used in the past to optimize the mechanical properties and impact toughness of low Carbon martensitic steel.

Vanadium Effect on a Medium Carbon Forging Steel

Metals, 2016
In the present work the influence of vanadium on the hardenability and the bainitic transformation of a medium carbon steel is analyzed. While V in solid solution enhances the former, it hardly affects bainitic transformation.

Microstructure, Defects, and Fatigue Response of High‐Strength Tool Steels

steel research international, EarlyView.
The martensitic tool steel family is designed for use in various working environments where they are subjected to repeatedly high mechanical loads. Despite the continuous upgrade of material´s microstructures through compositional development or processing techniques, defects remain a critical factor for the tool performance by leading to fatigue ...

Microstructure evolution of austenite-to-martensite transformation in low-alloy steel via thermodynamically assisted phase-field method

Journal of Materials Research and Technology
The austenite-to-martensite phase transformation plays a crucial part in the microstructure evolution of steel, with the morphology and grain size of martensite being key factors that influence the mechanical properties. This study explores the influence

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 ...

Effect of Ti and C Contents on Prior Austenite Grain Size in Ti Added Steels

Korean Journal of Materials Research, 2011
Prior austenite grain size plays an important role in the production of high strength hot-rolled steel. This study investigated the effect of Ti and C contents on the precipitates and prior austenite grain size. Steel with no Ti solutes had prior austenite grain size of about 620 .
