Alteration of Phase Transformation Behavior and Prior Austenite Grain Structure Due to Elevated Tramp Element Concentrations in a Hypoeutectoid Steel

open access: yessteel research international, EarlyView.
The phase transformation behavior of a hypoeutectoid steel is studied in comparison with alloys containing higher concentrations of tramp elements, simulating high recycling rates. The examination of microstructures reveals that the tramp elements facilitate the formation of displacive phases along with retained austenite.

Influence of Higher Tramp Element Level on the Weldability of Automotive Steels

open access: yessteel research international, EarlyView.
The use of green recycled steels is constantly expanding in the automotive industry. The increase in tramp elements resulting from the recycling of steel is problematic. Tramp elements can lead to a negative influence on the weldability. To understand the influence, the welding properties of three green steels are characterized. The potential limits of

Recycling End‐of‐Life Solid Oxide Cell Interconnect Assemblies into Commercial‐Grade AISI 304 Stainless Steels

open access: yessteel research international, EarlyView.
This study validates a recycling pathway for converting interconnect assemblies from end‐of‐life SOC stacks into commercial‐grade AISI 304 steels. Using scrap‐based steelmaking operations, austenitic cast steels with <4.0% δ‐ferrite are successfully produced.

Effect of Intrinsic Carbon in Hot Briquetted Iron on Melting and Refining Efficiency under Electric Arc Furnace Conditions for Sustainable Steelmaking with Active Use of H2‐Reduced Iron

open access: yessteel research international, EarlyView.
The melting behavior of hot briquetted iron (HBI) is observed and compared with FactSage computing simulation. When using HBI in an electric arc furnace process, a proper design of intrinsic carbon content in HBI, charging ratio of HBI, and addition of lime are proposed to be essential to control the slag volume, maintain slag basicity, and mitigate ...

Exploiting Residual Elements Arising from Scrap Steel in Future Sustainable Steel Alloy Design

open access: yessteel research international, EarlyView.
Herein, the effects of residual elements Cu and Sn on grain growth, recrystallization, and phase transformation in C–Mn steel are summarized, and a case study is presented on how the presence of residual elements can be exploited to reduce deliberate Nb microalloying while achieving the same grain size control and strength during thermomechanical ...
