A study of stacking faults in deformed austenitic stainless steel by X-ray diffraction

Abstract

Making use of the data obtained already in our laboratory on elongated, quenched samples of austenitic steel lCrl8Ni9, such as the effective domain size Deff, the average dislocation density-ρ, the average dislocation configuration parameter, -M, the range of strain field -Re, the elastic energy density 〈E/V〉,etc., some exact and clear expressions for the relation of intrinsic stack-ing fault (SF) density α′, extrinsic SF density α″, twin fault density β, SF energy γ, true particle size D0, minimum value of the fault width Tmin, and maximum particle size Dmax are given.
