Influence of Hot Forging Parameters on a Low Carbon Continuous Cooling Bainitic Steel Microstructure

Metals, 2020
Thermomechanical processing of low carbon bainitic steels is used to obtain a bainitic microstructure with good strength and toughness by continuous cooling after forging without the need of further heat treating, hence reducing manufacturing costs ...

A Comparative Study of Directed Energy Deposition‐Arc and Casting: Enhancing Mechanical and Thermal Properties of Hot‐Work Tool Steels

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.

Multifaceted Behavior and Functional Versatility of Ferritic Stainless Steels, Part I: Applications and Processing, a Review

steel research international, EarlyView.
This review investigates the processing‐microstructure‐property relationships in ferritic stainless steels (FSSs). It highlights advances in deformation behavior, heat treatments, surface modifications, and alloying effects. Theoretical models, including Johnson‐Mehl‐Avrami‐Kolmogorov, Arrhenius, nucleation theory, and diffusion theories, are discussed

Hot-forging of YBa2Cu3Oy ceramic powder.

Journal of the Japan Society of Powder and Powder Metallurgy, 1988
YBa2Cu3Oyセラミック粉末を金属モールド中に封入し,高温で一軸圧縮により短時間で圧縮させた。モールド中で円盤状に焼結したセラミックスについて,圧縮軸に垂直と平行な焼結体断面のX線回折測定を行った結果,結晶の(00Q)の面が圧縮軸と垂直な方向へかなり配向していることが確かめられた。このような配向性焼結体の配向度の表示方法,粒子配向の機構等について若干の考察を加えた。

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 ...

The effects of thermomechanical history on the microstructure of a nickel-base superalloy during forging [PDF]

, 2016
The effect of thermo-mechanical history on hot compression behaviour and resulting microstructures of a nickel base superalloy is presented. Hot compression tests were carried out on HAYNES® 282® specimens to varying strains from 0.1 to 0.8.
