Abstract
An evaluation of tensile and fatigue performances of dual phase steel subjected to change in the pre-strain path are presented in this work. Initially material is loaded up to a certain amount of pre-strain in the rolling or transverse direction, and after that specimen for tensile and fatigue tests are fabricated in the parallel or orthogonal to the pre-straining directions. Irrespective of pre-straining direction, all the pre-strained specimens show an increase in yield stress and simultaneous reduction in uniform elongation of the material, as well as improvement of high cycle fatigue life. The material exhibits better fatigue resistance for those specimens where fatigue testing is done orthogonal to the initial pre-straining direction.
