“…The hydrogen may be embedded into the growing foil and may give rise to marked mechanical effects, such as hydrogen embrittlement [42]. The metal may suffer severe loss of the ductility, toughness and strength as a result of the hydrogen embrittlement [43]. Thus, the hydrogen atoms in the deposits can result in the decreased hardness and tensile strength of the iron deposits.…”

“…Where the D is the hydrogen diffusion coefficient, C o is the constant hydrogen concentration at the charging side of the membrane, and L is the membrane thickness. The aim of the experiment was to measure the hydrogen diffusion coefficient of the steel, which was calculated from the breakthrough time using equation (2) .…”

“…First, if the coating is applied by electrodeposition a small proportion of the plating current produces hydrogen that is reversibly trapped in the coating and then slowly absorbed by the steel. This hydrogen can lead to delayed failure of high strength steel under load and it is the usual practice to bake such components for up to 24 hours at 200°C to remove the hydrogen [1,2]. Failure resulting from hydrogen uptake during electroplating is referred to as direct embrittlement.…”

This paper describes how hydrogen transport affects the severity of hydrogen embrittlement in 300M and AerMet100 ultra high strength steels. Slow strain rate tests were carried out on specimens coated with electrodeposited cadmium and aluminium-based SermeTel 1140/962. Hydrogen diffusivities were measured using two-cell permeation and galvanostatic charging methods and values of 8.0x10-8 and 1.0x10-9 cm 2 s-1 were obtained for 300M and AerMet100, respectively. A two-dimensional diffusion model was used to predict the hydrogen distributions in the SSR specimens at the time of failure. The superior embrittlement resistance of AerMet100 was attributed to reverted austenite forming around martensite laths during tempering.

This paper reviews the environmentally-assisted cracking studies of some of the key engineering materials i.e. austenitic stainless steels, aluminium alloys and magnesium alloys. Some of the salient work carried out by the research laboratories and institutions in India and other countries, in this critical research area, are brought out in this paper. Environmentally-AssistedCracking of Engineering Materials known as EAC. Stresses arise in practice from applied load or from residual stress due to welding or inhomogeneous plastic deformation.The literature on EAC of engineering materials is vast, and there are many useful textbooks and conference proceedings [1][2][3][4][5]. Understanding the EAC mechanism(s) in metals has been a subject of interest for decades.Basically, the EAC can be broadly classified into two groups: (i) anodic dissolution assisted cracking and (ii) hydrogen-induced cracking. Many models have been put forward, in literature, to explain the EAC mechanism(s). The slip-dissolution model is one of them explaining the crack growth occurring by extremely localized dissolution of the metal. This model states that the crack is protected by a film, usually an oxide, which is fractured as a result of plastic strain in the metal at the crack tip. The crack growth proceeds by a cyclic process of film-rupture, dissolution and filmrepair. This model has been mainly cited to explain the intergranular cracking of femtic steels in passivating environments such as carbonate-bicarbonate solutions as well as sensitised stainless steels in a variety of environments.Later, a film-induced cleavage model was proposed to explain the brittle failure of alpha-brass due to dezincification in ammonia solution. Hydrogeninduced cracking or hydrogen embrittlement in metallic materials is also widely accepted as a mechanism of failure in recent years. Hydrogen discharge and absorption are favoured when there is acidification of the local environment by cation hydrolysis, especially if this acidification damages or destroys a passive film in the crack. Once hydrogen is absorbed in the metal, it can promote cleavage, intergranular separation, or a highly localized plastic fracture. In hydride-forming metals such as Mg and Ti, formation of brittle hydrides can be part of the fracture mechanism.The research organisations and institutions in India have contributed significantly to the understanding of EAC behaviour of engineering materials. Some of the key research works carried out in this research area by
