Abstract
THE progress of creep in metals in the case of applied tensile stress is usually divided into three stages : (1) an initial decelerating rate of creep (primary creep) ; (2) a stage of approximately constant creep-rate (secondary or steady state creep) ; (3) a final accelerating state of creep, leading to fracture (tertiary creep often ascribed in materials undergoing large deformations to increase in stress due to decreasing cross-sectional area as creep proceeds).
