Influence of Austempering Temperatures on the Microstructure and Mechanical Properties of Austempered Ductile Cast Iron

Metals, 2021
The influence of the austempering temperatures on the microstructure and mechanical properties of austempered ductile cast iron (ADI) was investigated. ADI is nodular graphite cast iron, which owing to higher strength and elongation, exceeds mechanical ...

In-situ observation of liquid zinc-induced erosion behavior diffusion mechanism in zinc-coated 22MnB5 steel

Journal of Materials Research and Technology, 2020
In this study, the erosion of liquid zinc penetrating 22MnB5 steel during austenitization was investigated by an in situ method. High-temperature confocal laser scanning microscopy (HT-CLSM) results show that erosion occurred in several areas after ...

Role of aluminum on liquid metal embrittlement susceptibility for Zn–Al–Mg/Sn coated hot-formed steels

Journal of Materials Research and Technology, 2022
In order to reduce the susceptibility of liquid metal embrittlement (LME) on advanced high strength steels, this paper proposes a strategy to increase the thickness of the inhibition layer and retard the interdiffusion of Fe and Zn by adjusting the Al ...

Metastable Austenitic Steel Deformation at Low Temperature [PDF]

Proceedings of the 2nd International Symposium on Science at J-PARC — Unlocking the Mysteries of Life, Matter and the Universe —, 2015
Austenitic stainless steel type 304 is well known as a metastable steel that may be transformed to have different crystal structures during plastic deformation [1] leading increase in strength and elongation, i.e. transformationinduced plasticity (TRIP) [2].

Physics‐Informed Machine Learning for Sustainable Alloy Design: Toward a Recyclable Unified Q&P Steel

Advanced Science, EarlyView.
A physics‐informed property‐bridging framework links high‐throughput hardness screening to tensile performance in quenching and partitioning steels. By transferring metallurgically guided representations across properties, a single alloy composition is designed to achieve multiple strength grades through heat‐treatment tuning alone, offering a ...

The Post-forging Heat Treatment Process of 9Cr Martensitic Heat-resistant Steel [PDF]

Teshugang
9Cr martensitic heat-resistant steel is an important candidate material for ultra-supercritical steam turbine rotors. Due to the large size of the rotor forgings， there is a greater tendency for microstructure inheritance.
