Some Creep-Rupture Data Analytics as Applied to AISI 310S Superalloy Austenitic Stainless Steel Sheets at Elevated Temperatures and High Applied Stresses
Abstract: Creep-rupture of AISI 301S stainless steel is analyzed at 973-1073K and 40-150MPa. Various creep curves and creep rate curves are compared to understand the effect of temperature and applied load. Creep deformation and creep fracture mechanisms are manipulated from concerned mechanism maps. Creep deformation follows high temperature climb. Creep activation energy so obtained is 345KJ/mol. It is larger than activation energy for self-diffusion in pure FCC iron (that is 270-311kJ/mol). …
