E. Leveque et P. Delobelle, VALIDITY OF VISCOPLASTIC BEHAVIOR MODEL E XTENDED TO SEVERAL STEELS WITH COMPOSITION CLOSE TO THE AUSTENITIC 17-12 MO SPH GRADE, Revue de métallurgie, 90(12), 1993, pp. 1577-1586
This article concerns extension of a viscoplastic model, developed for
a particular austenitic stainless steel of the 17-12 Mo SPH grade (SQ
sheet), to several products with slightly different chemical and meta
llurgical compositions. Continuous traction. creep and fatigue tests a
t 500 and 600-degrees-C, realized on four sheets (SP, SQ, SR and Krupp
) have allowed a new identification of the model.
