Özet

Neutron diffraction and finite element (FE) modeling are used to investigate the thermal residual stress in W-fiber/bulk metallic glass-matrix composites. Results show that the W fibers are severely textured having a 〈1 1 0〉 texture along fiber axis. An elastic FE model predicts the thermal residual stresses. This suggests that both the fibers and the matrix effectively behave as elastic materials.

This study was supported by the Army Research Office (grant no. DAAD19-00-1-0379) and the National Science Foundation (CAREER Award 9985264). It also benefited from the national user facility at the Lujan Center (at LANSCE) supported by the US Department of Energy under contract W-7405-ENG-36. Helpful discussions with Professor W.L. Johnson (Caltech) on BMGs and Dr. R.B. von Dreele (LANSCE) on the use of the GSAS program are appreciated.
