强度各向异性通过拉伸和压缩试验发现，拉伸珠光体钢丝，其中压缩试验沿着相对于拉伸方向的0度、45度和90度方向对制备的试样进行。退火对这种各向异性强度的影响也进行了研究。为了弄清强度各向异性的来源，用中子衍射法测量了织构和残余应变。结果表明，铁素体和铁素体相的残余应力是强度各向异性的原因。
Strength anisotropy is found by tensile and compressive tests for a drawn pearlite steel wire, where the compressive tests are performed for prepared specimens along directions of 0, 45 and 90 degrees with respect to the drawing direction. The influence of annealing on such anisotropic strength is also examined. To make clear the origin of the strength anisotropy, texture and residual strain are measured using neutron diffraction. It is revealed that residual stresses in the ferrite and cementite phases are the cause of strength anisotropy.
