The martensite transformation in carbon steels

Proceedings of the Royal Society of London. Series A. Mathematical and Physical Sciences, 1961
Abstract Martensite formed in plain carbon steels containing less than 1·4% carbon has been studied by direct examination of thin foils in the electron microscope. It was found that the martensite in low-carbon steels forms predominantly as long needles parallel to <111>M while in the high-carbon steels it forms as ...

Martensitic Automotive Steels

Abstract Martensitic steels (MS) have the highest strength among the first-generation advanced high-strength steels (AHSS). Martensitic steels exhibit high tensile strength and high yield strength, making them ideal for producing safety parts for automobiles to protect passengers during collisions.

Martensitic Steels

Abstract Martensitic (MS) steel is produced by quenching carbon steel from the austenitic phase into martensite. This chapter presents the compositions, microstructures, processing, deformation mechanism, mechanical properties, hot forming process, and attributes of MS steels.

The crystallography of the martensite reaction in steel

Acta Metallurgica, 1961
Abstract Computer programmes have been prepared and used to examine the crystallographic features of the martensite reaction in steels. The criteria of low or minimum values of the shape shear and the slip or twinning shear were used in assessing the predictions.

Martensitic Stainless Steels

Abstract This article presents fractographs of martensitic stainless steels that failed by fatigue and stress-corrosion cracking. A sampling of fractographs in the article illustrate a 410 martensitic stainless steel heat shield from a turbine engine that failed in fatigue due to thermal cycling.

Activation Response of Martensitic Steels

Journal of Fusion Energy, 1997
A hypothetical martensitic steel has been compositionally designed in order to optimize both metallurgical and reduced activation properties. When compared with two other martensitic steels, its activation characteristics are shown to be superior for all activation indices examined. However, these excellent properties are found to be due to the assumed

The kinetics of martensite formation in steel

Metallurgical Transactions, 1971
The main features of martensite transformation kinetics observed in steels are surveyed. The quantitative analysis of the data relating to isothermal transformation is emphasized as the starting point for a more general understanding of other types of kinetic behavior.

Martensite in steel: strength and structure

Materials Science and Engineering: A, 1999
Abstract This paper reviews the strengthening mechanisms associated with the various components of martensitic microstructures in steels and other ferrous alloys. The first section examines the experiments and strengthening theories associated with Fe–Ni and Fe–Ni–C alloys, in which the martensite, because of subzero Ms temperatures, can be evaluated

Butterfly martensite in industrial steels

Metallography, 1987
Abstract The morphology and the conditions of formation of butterfly martensite observed in carbon tool steels, low-alloy tool steels and bearing steels have been investigated. The results indicated that the butterfly martensite in various steels in three dimensional space can be classified into two types: i.e., the butterfly martensite with tails ...
