Investigation of Microscopic Nonmetallic Inclusions in Powder Metallurgical High‐Speed Steels

steel research international, EarlyView.
Methods for inclusion analysis are evaluated for suitability. Various powder metallurgical steels in different processing states are characterized. SEM/EDS data are further analyzed using analytical and statistical approaches. A thermodynamic method for determining inclusion phase composition is tested.

Biocarbon Suitability Evaluation for Direct Injection in Blast Furnace Ironmaking

steel research international, EarlyView.
This study examines densified biocarbon for direct injection in blast furnace ironmaking to reduce greenhouse gas (GHG). Enhanced burnout performance, along with favorable reactivity and carbon structure of the combustion residue, supports its suitability for blast furnace injection. Modeling results indicate that up to a 27% reduction in GHG emissions

Outline of a Washing Treatment to Improve Electric Arc Furnace Slag Environmental Behavior

steel research international, EarlyView.
This study evaluates a water‐washing treatment for electric arc furnace slag to reduce the leaching of hazardous elements (Cr, Ba, Mo, and V), enabling its reuse. The process effectively decreases leachate concentrations. Using the treated slag as a substitute aggregate in concrete reduces greenhouse gases emissions by 42.5% compared to landfilling ...

Numerical Prediction of Deformation‐Induced Martensitic Transformation in Cold‐Sprayed Austenitic Stainless Steel

steel research international, EarlyView.
Cold spray deposition of stainless steel (grade: SS304) is evaluated for marine applications, with emphasis on martensitic transformation during impact. Analytical modeling, simulations, and experiments reveal that helium‐assisted spraying of fine powders promotes cooling below the martensitic start temperature, enabling up to ≈40% austenite to ...

Polyaniline as a dual flame retardant and electrostatic dissipative additive in polyethylene nanocomposites

Journal of Vinyl and Additive Technology, Volume 31, Issue 2, Page 339-355, March 2025.
Effecft of co‐doping polyaniline with phosphoric acid and phytic acid on the heat release rate of polyethylene. Abstract Polyolefins, such as polyethylene (PE), are highly flammable and electrically insulative, limiting their applicability. The study explored the flame‐retardancy and electrical conductivity of PE/polyaniline (PE/PANI) nanocomposites ...

Thermal Transport Properties of W2TMB2 Solid Solutions (TM = Fe, Co, Ni)

Zeitschrift für anorganische und allgemeine Chemie, EarlyView.
Thermal transport properties of W2TMB2 (TM: Fe, Co, Ni) and their solid solutions, as well as electron backscatter diffraction measurements, show interesting particularities depending on the TM type and content. In this work, thermal transport properties of W2FexCo1‐xB2, W2FexNi1-xCoB2, and W2NixCo1‐xB2 (x: 0.0, 0.2, 0.4, 0.6, 0.8, 1.0) were ...

Common misconceptions in crystallography and crystal optics

Journal of Applied Crystallography, EarlyView.
Six recurrent misconceptions in crystallography, some involving mineral and crystal optics, are analyzed and discussed. The explanation of these and similar misconceptions could serve as educational resources for teachers.Did you know that an X‐ray diffraction pattern is not a spectrum?
