Vodíková křehkost duplexní oceli typu 22/5

Abstract

Main objective is to establish predisposition of duplex steels of type 22/5 to hydrogen embrittlement. The work is to evaluate predisposition to hydrogen embrittlement by tensile test in the normal and slow loading speed. The main objective is to determine the mechanical properties of duplex (ferritic-austenitic) steel, index of hydrogen embrittlement, which provides information on hydrogen embrittlement of the material, and assessment of the fracture surfaces of samples the various schemes of hydrogen electrolytic saturation.
