Influence of high pressure and high temperature hydrogen on fracture toughness of Ni-containing steels and alloys
Journal Title: Archive of Mechanical Engineering - Year 2014, Vol 0, Issue 1
Abstract
The effect of hydrogen on short-term strength, low-cycle durability and planestress fracture toughness of 10Cr15Ni27 steel, 04Cr16Ni56 and 05Cr19Ni55 alloys at pressure up to 35 MPa and temperature 293. . . 773 K was investigated. The modes of hydrogen action for which the elongation delta, reduction of area ksi, low-cycle durability N and crack resistance parameters K_c of alloys are minimal were established: hydrogen pressure above 10 MPa (non-hydrogenated specimens of 04Cr16Ni56 alloy) and above 15 MPa (hydrogenated specimens of 10Cr15Ni27 steel and 05Cr19Ni55 alloy, hydrogen concentration 15 and 19 wppm, respectively).
