TL;DR: In this paper, the results of electrochemical extraction of secondary phases clearly indicated a two-slope behavior, and the initial smaller sloped line corresponded to the precipitation of the Cr2N phase while the line with larger slope at longer aging time was the domination of chi phase precipitation.

TL;DR: In this paper, a 15Cr-15Ni-2.2Mo-Ti modified austenitic stainless steel in the temperature range 300 to 1023 K was analyzed in terms of Ludwigson and Voce equations.

TL;DR: In this paper, the development of a microstructure in 304L stainless steel during industrial hot-forming operations, including press forging, rolling/extrusion, and hammer forging at different temperatures in the range 600-1200 degrees C, was studied with a view to validating the predictions of the processing map.

TL;DR: In this article, the tensile properties of deformed products were evaluated at room temperature and the influence of the processing conditions, i.e. strain rate and temperature on the deformed product were analysed to identify the optimum processing parameters.

TL;DR: In this article, a detailed SEM based study of the crack initiation and growth mechanism in the heat affected zone (HAZ) has revealed that grain boundary cavitation, triple point cracking and subsequent sub-surface linking up of the cavities into microcracks have been responsible for extensive damage in the HAZ.
