As AlSi-coated press hardening steel is heated to austenitization temperatures, various Fe−Al intermetallic compounds (e.g. FeAl, Fe2Al5 etc.) and voids are generated throughout the coating, increasing also surface roughness. The goal of this study investigate effects coating roughness, distribution on AlSi fracture during its deformation at elevated temperatures. For purpose, hot tensile exper...

The excellent catalytic activity of newly magnetic nanocatalyst FeAl 2 O 4 @PTMS-sulfaguanidine-SA in a one pot multicomponent Mannich-type reaction was used to obtain 2-piperazinyl quinoxaline derivatives with highly selective anti-proliferation efficacy.

Deleterious gases such as CO and H(2)S can cause degradation of steel by reacting with the metal surface. Here we consider whether alloying the steel surface might be able to inhibit these damaging surface reactions by raising the barriers to molecular dissociation. We employ first-principles density functional theory techniques to investigate the elementary reaction pathways and barriers for C...

Point defect concentrations in milled samples of stoichiometric FeAl were obtained by Mšssbauer measurements. Mšssbauer spectra consisted of a single absorption dip with broadening attributed to unresolved hyperfine interactions. A local environment model was used to analyze spectra that allowed for defect-induced changes in monopole interactions at Fe probe atoms due to elementary defects in t...
