Two‐Stage Isothermal Transformation of Austenite into Nanobainite in a Chemically Inhomogeneous Medium‐Alloy Steel Containing 0.5 wt% C

open access: yessteel research international, EarlyView.
The effect of chemical inhomogeneity on the microstructure and properties of nanobainitic steel is investigated. A two‐stage isothermal heat treatment that produced a more uniform microstructure is designed. The first‐stage temperature is higher than the MS of depleted bands; conversely, the second‐stage temperature is lower than the first‐stage ...

Recycling of Mill Scale Into High‐Purity Iron Through Hydrogen‐Based Reduction

open access: yessteel research international, EarlyView.
Mill scale, an iron oxide–rich steel by‐product, is difficult to recycle due to impurities. This study evaluates hydrogen‐based direct reduction and hydrogen plasma smelting reduction as low‐carbon recycling routes. Impurity segregation limits reduction kinetics. Direct reduction achieves 92% conversion in 180 min, while plasma reduction reaches 91% in

Near‐Atomic Investigation on the Elemental Redistribution During Coprecipitation of Nano‐Sized Kappa‐Type and B2 Precipitates in an Al‐Alloyed Lightweight Steel

open access: yessteel research international, EarlyView.
Elemental redistribution during coprecipitation of kappa (κ)‐type and B2 precipitates in an Al‐alloyed lightweight steel is revealed by atom probe tomography (APT) and density functional theory (DFT). Fe and Ni redistribution promotes the evolution of B2 phase from NiAl‐type toward FeAl‐type and improves the stability of κ and B2 phases during ...

Concrete in architecture: Redefining form, space, function, and insights from bibliometric analysis

open access: yesStructural Concrete, EarlyView.
Abstract Concrete has become a cornerstone in architectural and engineering innovation, as it seamlessly integrates structural performance with artistic expression. Its evolution from ancient opus caementicium to contemporary ultra‐high‐performance concrete illustrates its adaptability to the change in technological, environmental, and design paradigms.
