Influence of testing rate on Lüders band propagation in niobium microalloyed steel

Using thermal imaging camera during tensile testing of low carbon and Nb microalloyed steel influence of testing rate on start of plastic deformation was investigated. The results showed that the onset of plastic flow is significantly different in Nb steel. When testing Nb steel, above the yield poi...
