摘　　要：在生产试制的 Ｓｔ１５微碳深冲钢板中，选择ｒ变化、△ｒ一定和ｒ 一定、△ｒ变化的两组试样，对其进行织构测量及ＯＤＦ分析，进而对织构特征进行了描述，并分析了主要织构对ｒ，△ｒ值的影响特点结果表明：试制的这批 Ｓｔ１５微碳深冲钢板没有出现理想的γ〈１１１〉｜｜ＮＤ取向线织构，而是主要体现为γ取向线（Ψ＝０－９０°，θ＝１９°，φ＝４５°）和围绕γ〈１１１〉｜｜ＮＤ取向线从 Ψ=０°， θ＝５４．７°，φ＝６２．７°螺旋旋转到 ψ＝９０°，θ＝４０°，φ＝４５°的 Ｌ取向线其中， Ｌ取向线主要影响Ｆ值，织构越强γ值越大，但对△γ值不利．γ取向线主要影响面△γ值，织构越强面△γ值越小．但对γ值不利．强的Ｌ取向线织构配以较强的γ＇取向线织构可以获得良好的γ，△γ值．Mom St15 micro-carbon deep drawing steel sheets, two sets of samples with γvariant and △γ constant, and γ constant and △γ variallt, were selected to carry out texture measurement and ODF analysis. A description of the texture characteristics and an investigation on the effect of the main textures on the γ and △γ values were given. The results show that in the tested steel sheets no desired γ <111>||ND orientation line appears but γ' orientation line located at ψ=0-90°, θ=19°and φ =45°, and L orientation line located around γ<111>|| ND orientation line which spirally rotates from ψ=0°, θ=54.7° and φ=62.7° to ψ=90°, θ=40° and of φ＝45° occur. Among them, the L orientation line has a main influence on the γ value and the stronger the texture density, the higher the γ value is,but is somewhat detrimental to the △γ value; at the same time, the γ＇ orientation line has a major effect on the △γ value in an opposite way, but is somewhat deteriorative to the γ value. A strong L orientation line superposed by a relatively strong γ' orientation line may produce fine γ and △γ values.
