The invention discloses an XRD (X-
Ray Diffraction) method for determining a wire texture, and belongs to the technical field of wire texture determination. The method comprises the following steps:
processing a wire material and a blocky standard sample thereof into different
layers of cylindrical samples during measurement, measuring textures of
diffraction peaks of the samples, recording highest strength data and texture types of the textures of different
layers, and calculating a highest strength average value max1 of the different
layers; and respectively
cutting a plate-shaped
test sample and a standard sample, carrying out whole-body
texture measurement on the
test sample and the standard sample, recording the highest strength max and the
texture type, judging the overall texture range of the
wire rod, and comparing the maximum strength max and the
texture type max in the same texture strength interval and the
texture type matched with max1, thereby verifying that the method has extremely high accuracy. According to the determination method, the texture information integrity of the
wire rod sample is guaranteed to a great extent, the texture change rule of the
wire rod from the
surface layer to the core part is accurately determined, and more research and guidance bases are provided for the deformation state,
process improvement,
mechanical property and
microstructure analysis of the wire rod.
