A comparative study of the mechanical properties, fracture mechanisms and hydrogen embrittlement peculiarities was carried out using specimens austenitic CrNi steel produced by two different methods: wire-feed electron beam additive manufacturing conventional casting followed solid-solution treatment. Hydrogen-induced reduction ductility increase in yield strength are observed both methods. Des...

Abstract A review of sacrificial Zn–Ni electroplating coatings on high-strength steels is presented. These are used for heavy structural applications such as landing gears, etc., that subjected to high stresses and corrosive environments in service. The process involving aqueous electrolytes invariably produces hydrogen. emitted hydrogen can diffuse into substrate steel, contributing the delaye...
