ABSTRACT
This study aims to correlate the temperature increase induced by the strain rate of AISI 430 stainless steel sheets during the tensile test and considering the following strain rates: 0.001; 0.01 and 0.1 s-1. In order to record the evolution of the temperature until the fracture of the specimens, an infrared thermographic camera was used. The results of infrared thermography showed a gradual and uniform increase in temperature during the work hardening of the material and a drastic temperature elevation in the regions of localized necking and fracture of the specimens. For the deformation rate of 0.1 s-1 the highest temperature gradient between localized necking and fracture was observed (110 ºC).
