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

Mineralogical phase and formation mechanism of titanium-bearing protective layers in a blast furnace hearth

open access: yes工程科学学报, 2019
In theory and practice, TiO2-bearing iron ores are the preferred raw materials for prolonging blast furnace times due to their protection of the refractory lining of the hearth.

Using Thermodynamics and Microstructure to Mitigate Overfitting in Pellet Reduction Models

open access: yessteel research international, EarlyView.
A in time and space discretized, thermodynamically sound model for direct reduction of iron oxide pellets is described. The number of fitting parameters is drastically reduced compared to existing models. Nevertheless, fitting kinetic parameters based on conversion degree data alone leads to overfitting, which can be mitigated by correlating the ...

Study on the mechanical properties and pore structure of granulated blast furnace slag self-compacting concrete based on grey correlation theory

open access: yesJournal of Asian Architecture and Building Engineering
Variations in the mechanical properties and pore structure of granulated blast furnace slag self-compacting concrete were studied. The grey correlation theory established the relationship between mechanical properties and pore structure. The test results

Comparison of iron ore reduction in experimental blast furnace and laboratory scale simulation of blast furnace process

open access: yes, 2003
The reduction of iron ore pellets in an experimental blast furnace has been surveyed by dissection of the blast furnace. Results of the dissection, as well as some results of measurements taken in the blast furnace interior during operation, have been ...

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.
