between the parameters of the dieless drawing process and the microstructures of the QSi3-1 silicon bronze alloy. Combined with image processing techniques, grain sizes and grain-boundary morphologies..., and the boundaries can be characterized quantitatively by fractal dimensions. With the temperature of 600-800°C and the drawing speed of 0.67-1.00 mm·s?1, either a lower temperature or a higher speed......

auto panel part was investigated. However, the effect of material parameters on the deep drawing of thin-walled hemispheric surface part has less been analyzed. Hemispheric surface parts are the bases... drawing generally, with the minimum thickness at the region of punch radius and outside the die corner, and the maximum thickness at the flange area. Existence of thickness variation during......
alloy during drawing refined the grains from 10 to 5 μm under the influence of cold deformation,the basal texture was rotated around radius direction,the basal texture became dominant,and the texture transformed from drawing direction(DD)//<2111> to a point between <2111> and <2110>parallel to DD.The ultimate tensile strength of the wire was increased by 44.7% compared......
