Machinability analysis of microstructures in pre-hardening plastic mold steel 718
工程科学学报, 2020 Owing to strict dimension accuracy demands, pre-hardening treatment has been widely used in the mold for production of large plastic parts. However, the large volume of mold leads to the existence of tempered martensite and bainite structure on the cross

Friction stir welding of thin DH36 steel plate [PDF]
, 2013 A series of 4, 6 and 8 mm DH36 steel welds were produced using optimum conditions for friction stir welding (FSW). Comparator welds in the same thickness from the same plates were produced using a single sided single pass process submerged arc welds (SAW)

Fatigue &Fracture of Engineering Materials &Structures, EarlyView.ABSTRACT The deformation behavior of carbide‐bearing bainite (CBB) and carbide‐free bainite (CFB) under various loading conditions is investigated. Retained austenite (RA) in CFB enhances strength and ductility only under uniaxial tension through gradual strain‐induced martensitic transformation, yet deteriorates impact toughness and fatigue crack ...

Estimation of the Volume Percent of Normal and Nanostructured Bainite in Bainitic Steels
Materials Today: Proceedings, 2015 Abstract Estimation of the volume percent of bainite has been conducted using a powerful computational technique known as neural network. The model is proposed for ordinary bainitic steel in addition to the more recent class of super bainite steel which are attractive for many applications.

steel research international, Volume 96, Issue 7, July 2025.This article investigates the influence of aluminum concentrations on the microstructure and mechanical properties of air‐hardening ductile steels. The reduction of the aluminum contents below 0.5 wt% is unfavorable as it does not ensure sufficient toughness.

Understanding the interaction between a steel microstructure and hydrogen [PDF]
, 2018 The present work provides an overview of the work on the interaction between hydrogen (H) and the steel’s microstructure. Different techniques are used to evaluate the H-induced damage phenomena. The impact of H charging on multiphase high-strength

Distribution of Dislocations in Nanostructured Bainite
Solid State Phenomena, 2011 The dislocation density in ferrite and austenite of a bainitic microstructure obtained by transformation at very low temperature (300 °C) has been determined using transmission electron microscopy. Observations revealed that bainitic ferrite plates consist of two distinctive regions with different substructures. A central region in the ferrite plate is

steel research international, Volume 96, Issue 6, June 2025.The study investigates microstructural evolution during high‐temperature partitioning in medium‐carbon, high‐silicon aluminum‐aided steels, exploring phase transformations affecting the final microstructure. Quenching and partitioning processes, with varying primary martensite fractions, reveal significant austenite stabilization at 350 °C, but ...
