<正> 面心立方的Ni-Fe二元合金,经过大压下量冷轧以后,形成了集中的冷轧织构,主要为{110}<112>+{112}<111>,将它在1000℃以下退火,通过一次再结晶可以形成晶粒很小但很完善的立方织构。这一现象曾引起物理冶金学者们很大的兴趣,并且很早就在工业上取得应用。 Rathenau曾用48％Ni-Fe合金作为试样对Ni-Fe合金的二次再结晶进行了详细的研究,得到
The crystal texture of secondary recrystallization of 50%Ni-Fe alloy has been inves-tigated quantitatively with X-ray Laue method. The samples used throughout the investigationwere several sheets of 50%Ni-Fe alloy cold rolled with 98% thickness reduction. Samples annealedbelow 1000℃ produced a cubic texture with fine grain size, while samples annealed at highertemperatures (1070, 1150, 1250, and 1240℃) produced secondary recrystallization, the ori-entation of which are different from the cubic one but belong to several definite types of orien-tations. For each annealing temperature, about 30 crystals were selected from a sample sheet forthe orientation determination with Laue method. The percent abundance of the texture componentsat several annealing temperatures has been calculated according to the relative volume of the crys-tals with the different orientations.
