用X-射线极图方法研究含镍50％的镍-铁合金的轧制与再结晶织构,并观察立方织构的形成。 试样经过两类冷轧方法术;即压延率为(I)94％与(II)98.4％。两类试样分别在500°,600°,700°,800°,900°,1000°及1100℃熟炼1小时。 由实验得知立方织构在熟炼温度600℃即开始出现,随温度升高而增强。在第二类冷轧压延率为98.4％试样中,经1100℃熟炼1小时,得到完整的立方织构。 从实验观察到,在50镍-铁合金中立方织构采由～(123)[121]绕[111]-轴转动40°而形成,结果证明再结晶织构的形成符合于定向成长学说。

The rolling and recrystallization textures in a 50 percent Ni-Fe alloy have been studied,the X-ray pole figure method being employed. Meanwhile, the formation of the cubic texture in thisalloy has also been investigated. The samples used in the experiments have been given two kinds of cold reduction; i. e., (Ⅰ) 94percent and (Ⅱ) 98.4 percent. The samples of class Ⅰ and class Ⅱ both have been annealed for onehour at 500°, 600°, 700°, 800°, 900°, 1000° and 1100℃. From the experiments, the formation of the cubic texture was found to begin at 600℃, be-coming intensified with the raising of the temperature. The cubic texture in the samples belongingto class Ⅱ, which has been annealed for one hour at 1100℃, was found to be sharp and complete. From the experiments it may be shown that the cubic texture in the 50 percent nickel-iron alloyhas been formed from the rotation of～(123) [121] orientation about the [111]-axes for 40°. Theresults seem to verify that the development of the recrystallization texture in the nickel-iron alloyconforms with the theory of orientation growth.
