Abstract

Abstract

In this paper, SiC_f/TC11 composites were prepared by magnetron sputtering precursor wire method and hot isostatic pressing. Tensile properties and fracture mechanism of SiC_f/TC11 composites at room temperature and 500 ℃ were studied. The experimental results show that the tensile strength of SiC_f/TC11 composite at room temperature and 500 ℃ are 1 530 MPa and 1 553 MPa, respectively, which are significantly higher than that of the matrix TC11 titanium alloy. Compared with TC11 titanium alloy, the tensile strength increases by ～57% and ～133%, respectively, and the fiber reinforcement effect is remarkable. By observing the fracture characteristics and longitudinal section of SiC_f/TC11 composites, it is proposed that the tensile fracture mechanism at room temperature and 500 ℃ mainly includes reaction layer multiple fracture, fiber single fracture, fiber multiple fracture, fiber-matrix interface debonding, fiber pulling out, W core -SiC interface debonding, matrix fracture, sheath fracture, etc. In this paper, the multi-component fracture process of SiC_f/TC11 composites under tensile loading at room temperature and 500 ℃ is revealed.
