Pearlitic Lamellae Spheroidisation During Austenitization and Subsequent Temperature Hold [PDF]

open access: yesArchives of Metallurgy and Materials, 2017
Typical processing routes for bearing steels include a soft annealing stage. The purpose of this procedure is to obtain a microstructure containing globular carbides in ferritic matrix.

Austenitization of FerriticDuctile Iron [PDF]

open access: yesArchives of Foundry Engineering, 2014
Austenitization is the first step of heat treatment preceding the isothermal quenching of ductile iron in austempered ductile iron (ADI) manufacturing. Usually, the starting material for the ADI production is ductile iron with more convenient pearlitic ...

The influence of heat rate and austenitization temperature on microstructure and hardness of Hadfield steel [PDF]

open access: yesJurnal Ilmiah SINERGI, 2023
The As-Cast condition of Hadfield alloy usually contains (Fe, Mn)3C carbides around the austenitic grains, which promote brittleness, making the steel impractical in industry.

Physics-Informed Machine Learning for Sustainable Alloy Design: Toward a Recyclable Unified Q&P Steel. [PDF]

open access: yesAdv Sci (Weinh)
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 ...

Kinetics analysis of two stage austenitization in supermartensitic stainless steel [PDF]

open access: yes, 2017
The martensite-to-austenite transformation in X4CrNiMo16-5-1 supermartensitic stainless steel was followed in-situ during isochronal heating at 2, 6 and 18 K min−1 applying energy-dispersive synchrotron X-ray diffraction at the BESSY II facility ...

Decomposition of Austenite in Austenitic Stainless Steels

open access: yesISIJ International, 2002
Austenitic stainless steels are probably the most important class of corrosion resistant metallic materials. In order to attain their good corrosion properties they rely essentially on two factors: a high chromium content that is responsible for the protective oxide film layer and a high nickel content that is responsible for the steel to remain ...

Austenitization and formation of ausferrite structure in austempered ductile iron with dual matrix

open access: yesMaterials Research Express, 2022
The effect of austenitizing conditions on the microstructure and mechanical properties of an austempered ductile iron (ADI) with a dual matrix was investigated. Carbon diffusion plays a critical role in the phase transformation of austenitization.

Study of the Effect of Quenching and Tempering Modes on the Strength Level of Alloyed Structural Steels Used to Produce Fasteners

open access: yesMetals, 2022
The development of high-strength fasteners is required due to the modern trend of reducing the weight of engineering structures. At present, structural bolts of property classes 8.8–10.9 are widely used, and higher-strength bolts of property classes 12.9
