In situ composite formation in the Ni-(Cu)-Ti-Zr-Si system

In situ composites were synthesized by arc melting Ni-(Cu)-Ti-Zr-Si alloys. The X-ray diffraction patterns of rapidly cooled cast strips show a primary Ni(Ti, Zr) B2 structure superimposed on the diffuse scattering maxima from the amorphous phase. Compression test results show that the composite starts to yield at 1200 MPa and fractures at 1900 MPa.
