Title:
NIOBIUM-TITANIUM ALLOY PRECISION STRIP AND MANUFACTURING METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2024/093998
Kind Code:
A1
Abstract:
The present application relates to the technical field of niobium-titanium alloy preparation, and in particular to a niobium-titanium alloy precision strip and a manufacturing method therefor. The niobium-titanium alloy precision strip provided by the present application comprises the following components in mass percent: 46-57% of Ti and 43-54% of Nb, and the thickness of the niobium-titanium alloy precision strip is less than or equal to 0.6 mm. The manufacturing method for the niobium-titanium alloy precision strip provided by the present application comprises the following steps: cogging a cast ingot to obtain a slab, and forging the slab; heating the forged slab, and then performing warm rolling in multiple number of times of heating to obtain a strip blank, wherein a total processing rate of the warm rolling is 60-80%; and performing surface treatment on the warm-rolled slab to remove a surface oxide scale to obtain a cold-rolled blank; and performing roll-like cold-rolling on the cold-rolled stock by using a dedicated roller, wherein the dedicated roller is a profiled roller having a large middle diameter and a small edge diameter and having smooth transition, and the niobium-titanium alloy precision strip is obtained after cold-rolling.
