Intercritical annealing treatment of PHS2000 and study of its microstructure and properties

Journal of Physics: Conference Series, 2022
Abstract Dual-phase steel (also known as DP steel) is the most widely used ultra-high-strength steel in automobile covering parts and structural parts. Since the concept of automotive lightweight has been put forward and deepened, the development of higher strength grade DP steel and the study of its microstructure and properties are of ...

Effect of Intercritical Annealing on the Microstructural and Mechanical Behaviours of Dual-Phase Steels

Jurnal Kejuruteraan, 2020
The automotive industry is the main consumer of dual-phase (DP) steels which have relatively impressive mechanical strength. DP steels are also known to have good ductility and load-bearing property because of their hard martensitic microstructure in soft ferrite grains.

Effect of Intercritical Annealing Parameters and Starting Microstructure on the Microstructural Evolution and Mechanical Properties of a Medium-Mn Third Generation Advanced High Strength Steel

Metals, 2022
A prototype medium-Mn TRIP steel (0.2 C–6 Mn–1.7 Si–0.4 Al–0.5 Cr (wt %)) with a cold-rolled tempered martensite (CR) and martensitic (M) starting microstructures was subjected to continuous galvanizing line (CGL) compatible heat treatments. It was found

Effect of intercritical annealing with high cooling rate associated with cold deformation and subcritical annealing on microstructure and mechanical properties of SAE 52100

Journal of Materials Research and Technology, 2020
Conventional spheroidization heat treatments of bearing steels are long-term, therefore it is necessary to study alternatives to decrease the heat treatment time to save energy consumption. This work aimed to develop a new manufacturing route in order to

Transformations during Intercritical Annealing of a TRIP-assisted Steel.

ISIJ International, 1998
During intercritical annealing of cold rolled TRIP-assisted steel, ferrite matrix recrystallizes and austenite forms. After subsequent quenching, part of that austenite may remain at room temperature as retained austenite, while the other part transforms into martensite. Based on their respective origin, recrystallized ferrite grains were recognized as
