铝含量对GCr15钢带织构和深冲性能的影响胡文豪1,何光辉1(1.浙江省杭州市杭州钢铁集团公司技术中心)摘 要:在杭钢集团大生产的条件下,分析了不同铝含量对退火后GCr15钢带的织构,金相组织,晶粒取向,硬化指数n和塑性应变比r以及凸耳指数Δr的影响.试验结果表明:在[Al]s的质量分数为0.017%~0.027%时,铝对高碳的GCr15钢带的深冲成型性能影响规律与铝对低碳钢板基本一致,随着钢中铝含量的升高,r值升高,且{111}面有利织构含量增加,但相同铝含量下GCr15钢的r值比低碳钢却要小很多,n值则相差......

and deformation twinning in the whole deep drawing process. The texture of the CP-Ti sheet and its drawn part consists of rolling texture component and recrystallization texture component. The intensity and type of the initial texture varied during the drawing process are related to the production of deformation twinning and dislocation slip. Twinning weakens the initial texture by randomizing the orientations......
Extrusion Deformation Texture of SiC_W/Al Composites焦成革,姚忠凯,韩雅芳摘 要:<正> The interface orientation relationships betweenSiC whiskers and matrix have been studied byX-ray diffraction and crystallite orientation distri-bution functions (CODFs) analysis.The distribu-tion of SiC whiskers in Al matrix of the as-castSiCw/Al composite was nearly unperfect......
rolling was induced. The influence of hot rolling on the cube texture of pure Ni was discussed. Sharp cube texture on pure Ni was obtained by suitable hot rolling, cold rolling, and recrystallization treatment. This deformation texture of tape was studied using orientation distribution function (ODF). Orientation mapping, content of the cube texture, and grain boundary distribution were performed......
