Influence of Tramp Elements on Phase Transformations, Structure, and Properties of Scrap‐Based Steels: A Focused Review of Recent Developments

steel research international, Volume 97, Issue 8, Page 4067-4084, August 2026.
This review explains how impurities from recycled scrap affect steel production and performance. Even small amounts (far below 1%) of these impurities can change how steel behaves during fabrication but also affect the properties of the end product. With better understanding and targeted countermeasures, these challenges can be managed, enabling wider ...

A kinetic model of the austenitization behavior of additively manufactured 17-4 PH martensitic stainless steel

Journal of Materials Research and Technology
Austenitization is significant for understanding the microstructure and residual stress evolution in additive manufacturing of non-austenitic steels. However, the accurate modeling of austenite transformation of additively manufactured parts is rarely ...

Mathematical Model of the Processoof Pearlite Austenitization

Archives of Metallurgy and Materials, 2014
The paper presents a mathematical model of the pearlite - austenite transformation. The description of this process uses the diffusion mechanism which takes place between the plates of ferrite and cementite (pearlite) as well as austenite. The process of

The Influence of Rapid Tempering on the Mechanical and Microstructural Characteristics of 51CrV4 Steel

Metals
The microstructure and mechanical properties of a low-alloy medium carbon steel (Fe-0.5C-0.9Mn-1Cr-0.16V, in wt.%) were investigated after rapid tempering and compared with a conventionally tempered counterpart.

A prediction model for austenite grain size distribution of casting slab in thermal rebound process: Considering α-ferrite precipitation and re-austenization

Journal of Materials Research and Technology
The precipitation and re-austenitization behavior of α-ferrite during thermal rebound process of casting slab are crucial to the austenite grain size distribution. Accurately obtaining austenite grain size distribution plays an important guiding role for

Hot centrifugal coating: A novel method for enhancing diffusion bonding integrity at steel-brass interfaces

Results in Surfaces and Interfaces
Steel cylinders are widely used in industry, but their service life is often limited by corrosion and wear. Conventional coating methods generally produce only mechanical bonds and can lead to delamination and interfacial failure.
