The uniaxial tension-compression tests were conducted to evaluate Bauschinger effect in gun barrel high strength steel. The Bauschinger effect is originally defined as the phenomenon which plastic deformation causes a loss of yield strength restraining in the opposite direction. The Bauschinger effect factor (BEF), defined as the ratio of the yield stress on reverse loading to the initial yield stress, is a measure of the magnitude of the Bauschinger effect. As this factor is utilized to calculate the accurate residual stress in thick-walled cylinder after autofrettage process, evaluation of this factor is very important. The aim of the present paper is to evaluate the influence of plastic deformation and the behavior of the Bauschinger effect. From the experimental results, BEF is found to be a strong function of prior plastic strain. ,
