Jones, K. Wu] The deformation and failure of rapidly heated metals under constant-load conditions are an area of mechanics in which there has been little research. This is due in part to the experimental challenges involved in the creation of rapid temperature rises in a tensile test specimen and in producing the high strain rates necessary for maintaining a constant load. Additionally, there are the instrumentation problems associated with the measurement of the transient deformation and temperature changes of a metal subjected to this thermomechanical history. This paper focuses on the tensile deformation behavior of metals when rapidly heated (of the order of 100 K · s−1) by the passage of an electric current while a constant load is maintained by a servohydraulic actuator. Experimental observations on the deformation behavior of several metals are presented. The three competing processes, work hardening, annealing, and reduction in cross-sectional area, involved in the development of a tensile instability are examined and are related to the characteristics of the loading system and the temperature rise rate.
