... that reveals the shapes of part of the individual grains. Original magnification: 2000×. Source: Ref 10 A fracture is referred to as decohesive rupture when it exhibits little or no bulk plastic deformation and does not occur by dimple rupture, cleavage, or fatigue. This type of fracture is generally...

... hydrogen damage, and reviews hydrogen degradation in specific ferrous and nonferrous alloys. The preeminent theories for hydrogen damage are based on pressure, surface adsorption, decohesion, enhanced plastic flow, hydrogen attack, and hydride formation. The specific alloys covered are iron-base, nickel...

Examples include creep deformation and rupture at elevated temperature, or the brittle fracture of body-centered cubic (bcc) metals at low temperatures...

The major classes of creep mechanism, namely Nabarro-Herring creep and Coble creep, are then covered. The chapter also provides information on three primary modes...

..., must also be understood ( Ref 3.9 ). Currently, hydrogen embrittlement is not fully understood. Taking intrinsic embrittlement first, the two most widely accepted models are the decohesion theory ( Ref 3.10 , 3.11 ) and the enhanced plasticity theory ( Ref 3.12 ). Experimental evidence exists...

... then repassivates again. This process gives discontinuous growth that could produce the striations observed in some systems. The crack progresses by repassivation and cracking of the passive layer, with no attack of the base metal. This is called the tarnish rupture model. There is preferential dissolution...
