Abstract
This chapter reviews experimental studies of the hydrogen embrittlement of high strength steels. The focus has been on six types of steel, having distinctly different microstructures. The six steel types are the low alloy steels, high toughness secondary hardening steels such as AF1410, hot work die steels, martensitic secondary hardening stainless steels, maraging steels and precipitation strengthened martensitic stainless steels. The susceptibilities of these classes of steel to hydrogen embrittlement as measured by the effects of hydrogen on fracture initiation and subsequent crack growth are discussed when the steels are tested in hydrogen gas, when the hydrogen has been introduced by charging and when the hydrogen embrittlement is associated with stress corrosion cracking in distilled water or salt water.

A review of hydrogen embrittlement of martensitic advanced high-strength steels

TL;DR: In this paper, the effect of hydrogen embrittlement on martensitic advanced high-strength steels (MS-AHSS) is investigated. But, the results are limited to a few published works.
Journal ArticleDOI

The influence of microstructure on the hydrogen embrittlement susceptibility of martensitic advanced high strength steels

TL;DR: In this paper, the influence of microstructure on the hydrogen embrittlement of advanced high-strength steels is addressed, showing that fracture initiation is typically intergranular, transgranular or quasi-cleavage.

Hydrogen embrittlement of high strength steels: Determination of the threshold stress intensity for small cracks nucleating at nonmetallic inclusions

TL;DR: In this paper, the authors determined the threshold stress intensity factor for small cracks in high strength steels in a hydrogen environment by studying the failure of hydrogen precharged cylindrical specimens loaded in uniaxial tension.

A new model for hydrogen-assisted cracking (hydrogen “embrittlement”)

TL;DR: A new model for hydrogen-assisted cracking is presented in this article, which explains the observations of decreasing microscopic plasticity and changes of fracture modes with decreasing stress intensities at crack tips during stress-corrosion cracking and HAC of quenched-and tempered steels.

Equilibrium aspects of hydrogen-induced cracking of steels

TL;DR: In this paper, the threshold pressures, p ∗, of hydrogen and of deuterium gases necessary to cause crack propagation in AISI 4340 steel of 250 ksi yield strength, were determined as functions of plane-strain stress intensity factor K at room temperature.

Tempering of steel

G. R. Speich, +1 more
TL;DR: In this article, the authors present an understanding of the processes involved in the tempering of iron-carbon martensites and how they are affected by alloying elements, and how these processes overlap and occur on such a fine scale.

Hydrogen-induced intergranular fracture of steels

TL;DR: In the absence of sufficient segregated impurity, hydrogen produces enhanced cracking at relatively high stresses by concentrated plastic flow, a displacement-controlled phenomenon as mentioned in this paper, which can be demonstrated in steels that have been embrittled by the elements responsible for temper embrittlement and tempered-martensite embrittlements.
