Creep fracture maps for 316 stainless steel
Creep fracture maps for 316 stainless steel
Creep fracture processes may be plotted in the form of a map by using the equations for the times to fracture for each process. A new and simplified form of creep fracture map is introduced in which the logarithmic normalized stress is plotted against the reciprocal of the homologous temperature. In this form, both the field boundaries between the different fracture processes and the contours of constant time to fracture appear as straight lines. Maps are presented for 315 stainless steel using four different creep processes: transgranular creep fracture, triple point cracking, and intergranular cavitation controlled by either diffusion growth or power-law growth. It is demonstrated that a map constructed for 316 stainless steel having a grain size of 40 μm is in good agreement with published experimental fracture data.

Abstract
Creep fracture processes may be plotted in the form of a map by using the equations for the times to fracture for each process. A new and simplified form of creep fracture map is introduced in which the logarithmic normalized stress is plotted against the reciprocal of the homologous temperature. In this form, both the field boundaries between the different fracture processes and the contours of constant time to fracture appear as straight lines. Maps are presented for 315 stainless steel using four different creep processes: transgranular creep fracture, triple point cracking, and intergranular cavitation controlled by either diffusion growth or power-law growth. It is demonstrated that a map constructed for 316 stainless steel having a grain size of 40 μm is in good agreement with published experimental fracture data.
