Processes, Volume 13, Issue 2, February 2025, Article number 4412227-9717https://doi.org/10.3390/pr13020441https://dspace.lib.cranfield.ac.uk/handle/1826/23550This article belongs to the Special Issue Processing, Manufacturing and Properties of Metal and AlloysThis austenitising bending investigation was carried out in a vacuum environment with the forming rates of 1, 10, and 100 mm/min under a certain bending temperature of 900 °C by a thermomechanical simulator. The enhanced strength at the accelerated forming rate and on the compression/tension zones throughout the thickness of the bent plates was discussed in detail in terms of dislocation pile-up, smaller prior austenite grain size, dynamic recrystallisation, smaller martensite packet, and stress-neutral layer. Since the simulation results were validated to match the experimental trend, this investigation could be applied as a valuable reference to simulate the practical manufacturing process of railway fasteners.enAttribution 4.0 Internationalhttp://creativecommons.org/licenses/by/4.0/4014 Manufacturing Engineering40 Engineering4004 Chemical engineeringSi–Cr micro-alloyed steelaustenitising bendingFE modellingmicrostructuremechanical propertiesparent grain reconstructionArticle2227-9717564420441132
