description To contribute to the process design of rapid hot drawing for the manufacture of vascular stent microtubes, the deformation behavior of ZM21 tubes were studied comprehensively by a novel system. A laser speckle-based digital image correlation (DIC) system was introduced to measure the strain of the tubes with small diameters in resistance-heating-assisted testing. Sample structures were optimized for a uniform temperature distribution. Tensile tests were conducted at different strain rates by flowing continuous current directly through the tube. Constitutive model involving the current density was newly established to analyze the deformation and microstructure evolution. The results showed the laser speckle-based DIC system was reliable to measure the strain field of the tube. The true stress–strain curves within the gauge area and at the hot spot showed little differences in the hardening period but large differences in the softening period, especially at higher current densities. The plasticity of the studied tube was enhanced at a medium current density and a low strain rate. The newly proposed constitutive model successfully analyzed the hardening and softening behaviors associated with the microstructure evolutions of grain, recrystallization, and dislocation. An accurate characterization of the hot deformation for the tube has been achieved experimentally and theoretically.
