A coarse grained constituent recently discovered in high strength steel weld metals – Coalesced Bainite – was investigated with a serial section procedure for three-dimensional (3D) analysis using Focused Ion Beam (FIB) milling. Image planes of a coalesced bainite grain, 0.4 μm apart were acquired using the FIB. The data collected was then used to create a 3D model of the coalesced bainite grai...
Low-temperature bainite, obtained by the transformation of austenite at temperatures as low as 200oC for times as large as several days, has been reported to have extraordinary mechanical properties including the highest reported hardness of any bainitic steel. The unusual properties are a consequence of the fine scale of the microstructure, which contains bainite plates with thickness in the r...
A high-strength low-carbon construction structural steel was investigated in the laboratory. The various austenite grain sizes were obtained by austenitizing at different temperatures. effect of size on bainite transformation studied dilatometer. results show that microstructure steels mainly includes granular bainite, lath-like and martensite-austenite (M-A). changes from to with increase temp...
