Opis:: This study addresses the task of predicting the transformation plasticity induced during pha- se transformation of the 16MND5 carbon steel from austenite to bainite under low externally applied stress using a semi-theoretical model based on the Greenwood-Johnson mechanism. Both models proposed by Leblond et al. (1989) and Taleb and Sidoroff (2003) sufficiently describe the evolution of the TRansformation Induced Plasticity (TRIP) during continuous cooling of the austenitic phase. Nevertheless, TRIP values predicted by these models unde- restimate measured data through the first half of the transformation and overestimate them through the second half. So, we propose in this paper a method to improve Taleb’s model in order to remove discrepancies between theoretical and experimental results throughout the whole transformation and obtain a better description of experimental data.

Opis:: The austenitic stability and strain-induced martensitic transformation behavior of a nanocrystalline FeNiCrMoC alloy were investigated. The alloy was fabricated by high-energy ball milling and spark plasma sintering. The phase fraction and grain size were measured using X-ray diffraction. The grain sizes of the milled powder and the sintered alloy were confirmed to be on the order of several nanometers. The variation in the austenite fraction according to compressive deformation was measured, and the austenite stability and strain-induced martensitic transformation behavior were calculated. The hardness was measured to evaluate the mechanical properties according to compression deformation, which confirmed that the hardness increased to 64.03 HRC when compressed up to 30%.
