    摘要:

    為減少傳統(tǒng)工藝制備的鎢/銅薄板在壓力加工過程中產(chǎn)生過多缺陷，提高板材的力學(xué)和電學(xué)性能，設(shè)計了一種新型的具有Cu/WCu/Cu三明治結(jié)構(gòu)的超薄板，對比分析了兩種結(jié)構(gòu)板材在軋制過程中組織和性能的變化。結(jié)果表明：與傳統(tǒng)結(jié)構(gòu)試樣相比，三明治結(jié)構(gòu)試樣表面覆銅層能夠完成對基體表層鎢顆粒的包覆和孔隙的填充，進而實現(xiàn)表面改性；三明治結(jié)構(gòu)試樣在軋制過程中產(chǎn)生缺陷相對較少，加工硬化不明顯，抗拉強度和導(dǎo)電性能也優(yōu)于傳統(tǒng)試樣。

    Abstract:

    In order to reduce defects and improve the mechanical and electrical properties of W-Cu thin sheet under pressure process, a new Cu/WCu/Cu ultra-thin sheet with three-layer sandwich structure was designed, and then the changes of microstructures and properties of two structure specimens in cold-rolling process were compared and analyzed. The results show that compared with conventional structure specimens, the surface Cu-coated layer of the sandwich structure specimen can clad the tungsten particles and fill the pores on the surface of the substrate, thus achieve surface modification; in rolling process, sandwich structure specimens have relatively fewer defects, and working hardening is not obvious, the tensile strength and electrical conductivity are better than that of conventional structure specimens.
