Hesam Talebi, Master student at ETS and CM2P member, in his article titled “In Situ Study of Phase Transformations during Non-Isothermal Tempering of Bainitic and Martensitic Microstructures” investigated tempering behavior of bainite and martensite in a medium-carbon high-strength steel.


Abstract: Phase transformations during non-isothermal tempering of bainitic or martensitic microstructures obtained after quenching of a medium-carbon low-alloy steel was studied. The microstructures correspond to different locations of an as-quenched large-sized forged ingot used as a die material in the automotive industry. High-resolution dilatometry experiments were conducted to simulate the heat treatment process, as well as to investigate different phenomena occurring during non-isothermal tempering. The microstructures were characterized using optical and scanning electron microscopy. Dilatometry analyses demonstrated that tempering behavior varied significantly from bainitic to martensitic microstructures. Retained austenite, which exists between bainitic ferrite sheaves, decomposes to lower bainite causing a remarkable volume increase. It was found that this decomposition finishes below 386 °C. By contrast, martensite tempering was accompanied with a volume decrease due to the decomposition of medium-carbon martensite to low carbon martensite and carbides.

23-09-2017: Scientific Presentation about Mechanical Surface Treatment.

Professor Kermouche from Ecole des Mines de Saint-Etienn presented the latest findings of his team for CM2P’s researchers. Mr. Kermouch in his speech titled “ASSESSMENT OF MECHANICAL PROPERTY GRADIENTS AFTER IMPACT-BASED SURFACE TREATMENT USING NANO-COMPRESSION TESTINGaimed to present a methodology to quantify the mechanical property gradient in the near surface after impact-based treatments. This methodology was applied on a purity-controlled α-iron.
