Effect of cooling rate on the bainite fraction in low carbon martensitic steel: combined analysis of transformation kinetics and crystal curvature
Derived by means of EBSD, statistics of crystal curvature in quenched low carbon steel is analyzed with allowance for its transformation kinetics in terms of dilatometry data. Based on curvature spectra sensitive to the distribution of dislocation density, fractions of martensite and bainite are quantified at high and low cooling rates. Distinction between the resulting microstructures is ascribed to various proportions of their athermal and thermally activated (rate-dependent) constituents.
期刊介绍：
The aim of "Letters on materials" is to provide a fast publication of short research and review articles on various topics in materials science and related areas of material physics and mechanics. The editorial board sees it''s own task in rapid informing of the readers on the state-of-the-art challenges and achievements in materials science. The editorial board does its best to select high quality papers reporting new scientific results that are of interest for researchers in materials science, physics, and mechanics. "Letters on materials" invites Russian and foreign researches to publish papers in both the Russian and English languages. The scope of the journal covers the following research areas: structure analysis of materials, mechanical and physical properties of materials, production and processing of materials, experimental methods of investigation of materials, theory and computational methods in solid state physics. "Letters on materials" is designed for researchers, engineers, lecturers, and students working in the areas of materials science, mechanical engineering, metal forming, physics, and material mechanics.
