Abstract
Thermal residual stresses in W fibers/Zr-based metallic glass composites were measured by in situ high energy synchrotron X-ray diffraction (HEXRD). The W fibers for the composites were 300, 500, and 700 μm in diameter, respectively. Coaxial cylinder model (CCM) and finite element model (FEM) were employed to simulate the distribution of thermal residual stress, respectively. HEXRD results showed that the selected diameters of W fiber had little influence on the value of thermal residual stresses in the present composites. Thermal residual stresses simulated by CCM and FEM were in good agreement with HEXRD measured results. In addition, FEM results exhibited that thermal residual stress concentrated on interface between the two phases and area where the two W fibers were the closest ones to each other.
