Optimization of the mechanical properties of low-carbon steels by formation of a multiphase microstructure
(2001-12-01)
In this work five methods of heat treatments are investigated in order to obtained convenient volume fractions of ferrite, bainite, martensite and retained austenite, starting with a low carbon steel and seeking the ...

Determination of the volume fraction of retained austenite in a 300m steel by heat tinting technique
(2007-12-01)
Applying the Heat Tinting Technique the microestrutural characterization of a 300M steel (medium carbon steel) was accomplished. The steel was austenitized for 20 min to 900°C, followed by holding at 400°C (in the bainitic ...

MICROSTRUCTURAL CHARACTERIZATION OF DUAL AND MULTIPHASE STEELS APPLIED TO AUTOMOTIVE INDUSTRY
(Trans Tech Publications Ltd, 2014-01-01)
TRIP (Transformation Induced Plasticity) and DP (Dual-Phase) steels are written in a new series of steels which present excellent mechanical properties. As for microstructure aspect, TRIP steels consist on a ferrite matrix ...
Microstructural effects on fatigue crack growth behavior of a microalloyed steel
(2010-04-01)
Thermal transformations on microalloyed steels can produce multiphase microstructures with different amounts of ferrite, martensite, bainite and retained austenite. These different phases, with distinct morphologies, are ...
