    摘要:

    采用XRD研究了Ni47Ti44Nb9鍛造板坯織構、不同熱軋、冷軋方向板材織構。研究表明，鍛造板坯有典型的γ取向線織構，鍛板心部最強取向在{111}<112>。沿軋向(RD)、交叉方向(CD)、橫向(TD)熱軋板織構類型相似，主要有3條取向線織構，接近{114}、{223}、{332}（或{221}），{332}面織構取向密度最強，最強織構分別為{221}<110>、{332}<113>、{332}<023>，不出現(xiàn)γ-織構。沿與軋向成0o、45o、90o方向二次冷軋最強織構近似為{332}<110>。90o方向二次冷軋織構強度最高，有多個強織構組分，γ-織構得到顯著加強

    Abstract:

    Ni47Ti44Nb9 alloy plate texture has important influence on the shape memory property, so it is necessary to control the texture. The different rolling direction textures of the forged plate, the hot-rolled and the cold-rolled plates were investigated. Results show that the texture of the forged plate center presents a typical γ-fiber with a peak at {111}<112>. The textures of the plate hot-rolled along rolling direction(RD), cross direction(CD) and transverse direction(TD) mainly consist of three fiber types: {114}, {223}, {332} (or{221}), among them {332} has the strongest orientation density，and γ-fibre does not appear. The strongest textures of the plate hot-rolled along RD, CD and TD, are respectively {221}<110>, {332}<113> and {332}<023>, respectively. The secondary cold-rolled plate along RD, 0o, 45o and 90o to RD, has approximately the strongest {332}<110> texture. The secondary cold-rolling texture of 90°to RD has the highest orientation density, and the γ-fibre is significantly strengthened
