TL;DR: In this paper, the effect of strain rate (in the domain of 0.001 to 10 s−1) on dynamic recrystallization (DRX) kinetics in a nitrogen-enhanced 316L(N) stainless steel during high temperature [≥1123k (≥850k)] deformation is reported.

TL;DR: In this article, the dynamic recrystallization (DRX) behavior of a nitrogen enhanced 316L(N) stainless steel has been studied in the temperature range of 1073-1423 K and strain rate range of 0.001-10 s−1 to understand the correlations between dynamic softening phenomena and efficiencies of hot working domains in the processing map.

TL;DR: In this article, a 316L stainless steel was subjected to severe shot peening: followed by plasma nitriding at 400°C for 4h. Results showed that this duplex treatment led to formation of about 45μm thick nitride layer; without CrN precipitation.

TL;DR: In this paper, the microstructural features of the peened layer and deformation induced martensite through transmission electron microscopy technique were analyzed for AISI 316 grade austenitic stainless steel.

Abstract: Iron pyrite is gaining reputation amongst the various alternatives for silicon as the photovoltaic material in solar cells due to its low cost, strong absorption and relatively high abundance of its constitutional elements. The synthesis of iron pyrite nanoparticles by existing hydrothermal methods with precise control over size, shape and stoichiometry is a difficult task due to the difficulty in controlling the parameters at a higher temperature. Here, we report a novel synthesis method for obtaining iron pyrite nanorods through a low temperature process in a stirred container which is scalable for the large scale industrial production. The nanorods synthesized by the new method consisted of single phase pyrite, possessing an optical band gap of about 1.13 eV. The overall mechanism of nanorod formation is explained by the La Mer model as well as the oriented attachment model.
