Bainitic Transformation and Properties of Low Carbon Carbide-Free Bainitic Steels with Cr Addition

Metals, 2017
Two low carbon carbide-free bainitic steels (with and without Cr addition) were designed, and each steel was treated by two kinds of heat treatment procedure (austempering and continuous cooling).

Austempering transformation kinetics of austempered ductile iron obtained by Mössbauer Spectroscopy

, 2020
The composition of metallic matrix in ductile iron as-cast and after austempering at temperatures of 280, 330 and 380oC (ADI) was examined. The study presents the results of these examinations obtained by Mössbauer spectroscopy. The specimens were taken from cast rods of 60mm diameter. Using calculated values of the parameters of hyperfine interactions
