Problems solved by technology

The patent with the publication number CN102825857A (publication date 2012.12.19) discloses a non-magnetic textured Ni-based alloy composite substrate and its preparation method. Since the composite ingot is obtained by discharge plasma sintering, it needs to be sintered under vacuum conditions. Sintering, the operation process is complicated, and the sintering equipment and maintenance costs are very expensive, so it is not suitable for industrial production of composite substrates with strong cubic texture

Abstract

The invention discloses a preparation method for a nonmagnetic and high-strength texture nickel-based alloy composite baseband. The preparation method comprises the following steps: cleaning the surface of a nickel-tungsten alloy billet with 9%-10% (in percentage by weight) of tungsten atoms, then, fixing the surface into a bottom-pouring type casting system as a core layer of the composite billet; proportioning nickel blocks and vanadium blocks in terms of 9% (in percentage by weight) of vanadium atoms, putting proportioned mixed materials into an electromagnetic induction vacuum smelting furnace to smelt, casting a refined liquid-state nickel-vanadium alloy material into a casting system, and filling a mould cavity with the liquid-state nickel-vanadium alloy material, thereby obtaining a layered composite billet, wherein the composite billet is divided into three layers, the outer layer is made of nickel-vanadium alloy with 9% of vanadium atoms, and the core layer is made of nickel-tungsten alloy with 9%-10% of tungsten atoms; and carrying out proper thermal treatment on the composite billet, then, carrying out large-deformation cold rolling and recrystallization annealing, thereby preparing the nonmagnetic and high-strength texture nickel-based alloy composite baseband. The preparation method is simple and easy to operate, is low in cost, and is suitable for industrial production.

Description

technical field [0001] The invention relates to a method for preparing a non-magnetic, high-strength textured nickel-based alloy composite substrate, and belongs to the technical field of high-temperature coated superconductor toughened textured metal substrates. Background technique [0002] Compared with the first-generation bismuth-based superconducting wires, yttrium-based coated superconducting materials have high irreversible field and high current-carrying capacity, so they are more competitive and more promising for commercial production and large-scale application. a superconducting material. The calender-assisted biaxially textured baseband preparation technology invented by the Oak Ridge National Laboratory of the United States, namely RABiTS technology, is one of the main technical routes studied by scholars at home and abroad. RABiTS technology obtains a sharp cubic texture through large deformation rolling and heat treatment of the metal substrate, and then tr...
