An Informatics Based Approach to Reduce the Grain Size of Cast Hadfield Steel

Abstract

Materials Informatics concept using computational intelligence based approaches are employed to bring out the significant alloying additions to achieve grain refinement in cast Hadfield steel. Castings of Hadfield steels used for railway crossings, requires fine grained austenitic structure. Maintaining proper grain size of this component is very crucial in order to achieve the desired properties and service life. This work studies the important variables affecting the grain size of such steels which includes the compositional and processing variables. The computational findings and prior knowledge is used to design the alloy, which is subjected to a few trials to validate the findings.

Synthesis of 1,4‐Disubstituted 1,2,3‐Triazoles from Terminal Vinyl Sulfones in Ionic Liquid: A Metal‐Free Eliminative Azide‐Olefinic Cycloaddition Route to Triazolyl Carbohydrates and Triazole‐linked Bissaccharides

“…116-120 °C; [α] 29) and (30). Following Method B described for 25, compound 3 a (0.109 g, 0.29 mmol) was reacted with bisazide 28 [28] (0.023 g, 0.14 mmol) in DAF:water (v/v 1:1, 3 mL) in 4 h to afford a mixture of compounds. The faster moving compound was isolated as a colorless gum 29 (0.039 g, 75 %).…”
