steel research international, EarlyView.The study investigates the influence of DED‐Arc/M versus casting on the microstructure and material properties of X40CrMoV5‐1 (AISI H13) hot‐work tool steel. DED‐Arc/M yields finer microstructures, superior mechanical strength, and ductility, but slightly reduced thermal conductivity.

Alloy Qualification for Producing Quench and Tempered Plate Steels with Extra‐Heavy Gage
steel research international, EarlyView.This study develops alloy concepts for ultraheavy steel plates (>100 mm) with ≥690 MPa yield strength. Through dilatometry and Jominy testing, the effects of Mo, Ni, and B on hardenability are quantified. A synergy between 0.5% Mo and 0.5%–1.0% Ni ensures core strength at low cooling rates, while boron microalloying suppresses ferrite and promotes ...

Grain-size distribution of volcaniclastic rocks 1: A new technique based on functional stereology [PDF]
, 2012 The power of explosive volcanic eruptions is reflected in the grain size distribution and dispersal of their pyroclastic deposits. Grain size also forms part of lithofacies characteristics that are necessary to determine transport and depositional ...

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 ...

MetalsThe superelasticity of CuZr shape memory alloys (SMAs) originates from stress-induced transformations between the B2 (austenite) and B19’ (martensite) phases. Grain size is a key parameter affecting the superelasticity of shape memory alloys.

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 ...
