The study of hydrogen transport properties and hydrogen embrittlement effects for iron–nickel (Fe–Ni) binary alloy is important since the major compositions that make up several nickel-based, nickel–iron-based superalloys, and austenitic stainless steels are essentially based on the ternary system of Fe–Ni–Cr, where the nominal composition of Cr is 15–18 wt%.


X-ray diffraction line broadening revealed that allotropic transformation between face-centred-cubic phase (fcc) and hexagonal close-packed phase (hcp) in cobalt is grain size dependent and also on the accumulation of structure defects. The results showed that the phase formation of cobalt depends on the mill intensity that influences of both ...
