Abstract

Creep-exposure generally is characterized by two processes mutually affecting each others material exhaustion and change of microstructure /1/. According to simple lifetime fraction rule service-exposure should cause a parallel shift of the creep rupture isotherms for the as-delivered condition towards lower stress values. The experimental results on creep-exposed material, however, are quite different (Fig. 1). For high stresses a considerable decrease in rupture time is observed, whereas in the lower stress regime the rupture times of service-exposed and new material become comparable.
