Embodiment 2

[0080] The 304 austenitic stainless steel wire with a width and thickness of 300 μm was subjected to multi-pass liquid-cooled temperature-controlled ultrasonic rolling continuous impact treatment, and the low-temperature ultrasonic rolling impact device used was the same as that in Example 1.

[0081] The above-mentioned ultrasonic transducer 3 converts electrical vibration into 20 kHz ultrasonic waves, and the ultrasonic horn further amplifies the amplitude to drive the GCr15 bearing steel rigid impact roller 11 (diameter 6 mm, width 10 mm; surface groove width 300μm, depth 1mm; surface roughness (Ra): 0.1μm, hardness: 64 HRC) to generate longitudinal high-frequency vibration; use a laser displacement sensor to measure the vibration amplitude, and the end amplitude is 30μm; fix the ultrasonic horn to make the impact The distance between the rigid roller column 11 and the rigid roller 8 is the sum of the ultrasonic amplitude and half the thickness of the wire, that is, 30+150=1...

Description

technical field [0001] The invention relates to the technical field of severe plastic deformation (SPD) fine grains, in particular to a high-performance wire production process and device for ultra-fine metal wires or ultra-thin strips. Background technique [0002] Severe plastic deformation (Sever Plastic Deformation—SPD) has great potential to refine the grains of coarse-grained materials to the nanometer level, and is a unique ultrafine-grained (nanocrystalline or submicron) Crystal) metal and its alloy material preparation process. It means that the material is at a lower temperature (usually lower than 0.4T m ) environment, severe plastic deformation occurs under the action of large external pressure, thereby refining the grain size of the material to a process of submicron or nanometer level. Strong strain and large plastic deformation can significantly refine the microstructure of metallic materials at low temperature, thereby greatly improving their strength and t...
