Tensile Behavior of Intercritically Annealed 10 pct Mn Multi-phase Steel [PDF]

Metallurgical and Materials Transactions A, 2013
The exceptional elongation obtained during tensile testing of intercritically annealed 10 pct Mn steel, with a two phase ferrite–austenite microstructure at room temperature, was investigated. The austenite phase exhibited deformation-twinning and strain-induced transformation to martensite.

The Influence of Subcritical Annealing and Cold Working on the Hydrogen Embrittlement Susceptibility of X65 D Pipeline Steel

Materials and Corrosion, Volume 76, Issue 10, Page 1478-1496, October 2025.
This study investigated the effect of subcritical heat treatment and cold work on the hydrogen embrittlement (HE) susceptibility of the X65 D pipeline steel. Hydrogen charging reduced the ductility of all specimens. Both subcritical annealing and cold working decreased somewhat the degree of HE.

Effects of intercritical annealing time on microstructure, tensile properties, and cryogenic toughness of newly designed ultra-low C low Ni Medium-Mn steel

Journal of Materials Research and Technology
An ultra-low carbon and low nickel medium manganese heavy steel plates was fabricated by quenching and intercritical annealing process. The effect of annealing time on the tensile properties and impact toughness were studied in relation to the formation ...

Vanadium Precipitation During Intercritical Annealing in Cold Rolled TRIP Steels

ISIJ International, 2007
Flat carbon steel manufacturers are currently developing new TRansformation Induced Plasticity (TRIP) steels as a response to strong demands for vehicle lightening and security reinforcement from the automobile sector. Compared to conventional high strength steels these advanced grades exhibit a very favourable compromise between strength and ductility

Tailoring the deformation behaviour of a medium Mn steel through isothermal intercritical annealing

Materialia, 2022
A novel concept of varying the strain hardening rate of a medium Mn steel with 8 wt\% Mn by varying the duration of the intercritical anneal after hot rolling was explored. It was found that the stability of the austenite phase showed an inverse square root relationship with intercritical annealing duration and that the maximum strain hardening rate ...

High‐throughput investigation of processing–microstructure relation in quenching and partitioning steels via gradient heat treatment and rapid characterization

Materials Genome Engineering Advances, Volume 3, Issue 3, September 2025.
This study proposes a novel high‐throughput experimental method integrating gradient heat treatment and advanced characterization techniques. This method can efficiently establish the processing–microstructure relation in quenching and partitioning steels. As quenching temperature decreases, the fraction of retained austenite initially increases due to

Experimental investigation of the influence of the HAZ on the strength of welded T‐joints made of HSS

Steel Construction, Volume 18, Issue 3, Page 209-222, September 2025.
Abstract The welding process introduces heat, which may cause softening in the heat‐affected zone (HAZ) of high‐strength steels (HSS). In welded components such as hollow section joints, this localised reduction in strength can reduce the load‐bearing capacity by promoting early failure of the joint and decreasing plastic design strength.

Loading Surface in the Course of Mechanical- Thermal Treatment and Steady-State Creep of Metals [PDF]

, 2013
: Kinetics of the loading surface of a material gives precious information on the level of the hardening of the material. This paper is concerned with the evolution of the loading surface during successive actions, such as: (i) plastic deformation, (ii)
