摘要

通过渗流铸造法制备了含不同直径W纤维增强体的锆基非晶复合材料,其中W纤维的直径分别为1000, 700, 500和200μm.以此为基础系统研究了W纤维直径对复合材料的准静态和动态压缩力学性能的影响.结果表明, 随纤维直径的减小, 纤维强度增大, 复合材料的面体率增大,非晶基体的小尺寸效应增强, 导致复合材料的静态压缩性能提高. 而动态压缩载荷下,相同子弹发射压力下, 随纤维直径的变化,复合材料所获得的应变速率也随之发生改变. 纤维直径为500μm时,复合材料的动态抗压强度最大, 复合材料的应变速率敏感指数也最大.

Abstract

The Zr-based metallic glass composite containing four kinds of W fibers with different diameters are prepared by infiltration casting method. The diameters of the W fibers are 1000, 700, 500 and 200μm,respectively. The effect of fiber diameter on the quasi-static and dynamic compressive mechanical properties and deformation behaviors of the composites was investigated. The results show that the quasi-static compressive properties improve with the decrease of the W fiber diameters, which is attributed to the increasing interface area and the size effect of the metallic glass matrix. Under dynamic compressive loading, the strain rate changes with the variation of the W fiber diameter at the same bullet firing pressure. The dynamic compressive strength and strain rate sensitivity exponent of the metallic glass composite with a fiber diameter of 500μm is the highest among the four W fiber/Zr-based metallic glass composites.

Key words： W fiber; metallic glass composite; shear band; strain rate; interface
