High Strength High Carbon Low Alloy Pearlite-Ferrite-Tempered Martensite Steels

Transactions of the Indian Institute of Metals, 2014
High strength multiphase steels have been developed consisting of combination of pearlite, tempered martensite and small amount of ferrite, by suitable heat treatment of a high carbon low alloy rail steel (0.7 % C). The desired microstructure has been obtained by holding fully homogenized steel in pearlitic range for small durations followed by water ...

Microstructure and Mechanical Properties of Martensitic High-Strength Engineering Steel

Metallurgist, 2020
A promising martensitic steel with good hardenability is studied. In the cooling rate range 0.1–30°C/sec and the only transformation recorded by a dilatometer starts at an Ms temperature of 355 ± 10°C. Microstructure and mechanical properties of the steel studied are analyzed after various heat treatment regimes: cooling from the austenitizing ...

Low-carbon high-strength alloy steels of the martensitic class

Metal Science and Heat Treatment, 1980
1. We investigated new high-strength low-carbon steel of the 15Kh3G3MF type with a good combination of mechanical properties: σb = (14-13)· 108 Pa; σ0.2 = (10.7-9.8) · 108 Pa; ψ=60–57.5%; δ=14–12%;a1 = 11.3-8.7 daJ/cm2) 2. The optimal heat treatment for this steel is oil quenching from 920±10°+tempering at 200° with cooling in water or ...

Vibration Stress Relief Treatment of welded high-strength martensitic steel

Welding in the World, 2011
The influence of a vibration stress relief (VSR) treatment on the residual stresses for welded specimens of ultra high-strength steel (ARMOX 500T®) was investigated. For the residual stress measurements X-ray diffraction and magnetic Barkhausen noise analysis (BNA) were utilized.

Hydrogen Trapping in Some Automotive Martensitic Advanced High‐Strength Steels

Advanced Engineering Materials, 2017
Hydrogen permeation experiments are used to investigate hydrogen trapping in commercial automotive martensitic advanced high‐strength steels. Hydrogen trapping increases with increasing mechanical strength, as indicated by (i) the decrease in the hydrogen diffusion coefficient, and (ii) the increase in reversible hydrogen trap density.

Hydrogen Embrittlement Testing of High Strength Low Carbon Martensitic Steels

CORROSION 2010, 2010
Abstract High strength carbon steels are being used as the external reinforcement for a novel composite pipeline. This system combines a thin wall corrosion resistant alloy with the reinforcement to produce a high pressure pipeline which is manufactured on site giving a lower cost alternative to conventional thick-wall pipelines. Despite

Martensitic Transformation in a Low-Alloy Ultra-High-Strength Steel

Advanced Materials Research, 2011
Martensitic transformation is the most important phase transformation strengthening the 30CrNi3MoV ultra-high-strength steel during heat treatment process. Characteristics of the martensitic transformation in the 30CrNi3MoV steel were investigated by means of dilatometric measurements and microstructural observations.

Vanadium Microalloyed High Strength Martensitic Steel Sheet for Hot-Dip Coating

2015
Cold rolled steels with various vanadium and nitrogen levels have been treated to simulate the application of galvanizing and galvannealing to hardened martensitic microstructures. Strength levels were raised 100–150MPa by alloying with vanadium, which mitigates the effect of tempering.

Thermal Desorption Analysis of Hydrogen in High Strength Martensitic Steels

Metallurgical and Materials Transactions A, 2011
Thermal desorption analyses (TDA) were conducted in high strength martensitic steels containing carbon from 0.33 to 1.0 mass pct, which were charged with hydrogen at 1223 K (950 °C) under hydrogen of one atmospheric pressure and quenched to room temperature.
