Title:
COMPOSITE SHIELDING YTTRIUM-BASED ALLOY MATERIAL, AND PREPARATION METHOD THEREFOR AND USE THEREOF
Document Type and Number:
WIPO Patent Application WO/2024/055747
Kind Code:
A1
Abstract:
The present application relates to a composite shielding yttrium-based alloy material. The main components of the yttrium-based alloy material comprise the following components in percent by mass: B: 0.05-10.0%, Cr≤6.0% or Al≤5.0%; and the remaining components of yttrium and other inevitable impurities. The grain size of the yttrium-based alloy material is 10-50 μm. Also provided are a preparation method for and a use of the composite shielding yttrium-based alloy material. The composite shielding yttrium-based alloy material of the present application can be used in a high-temperature environment of 600 to 1,000°C, has fine grains, relatively high strength and toughness and low density, and is a high-quality and efficient neutron moderation and absorption integrated alloy material.
