Abstract:
A novel in situ reaction synthesis process, reaction technique in melt, was developed. An in situ particle reinforced Al 4.5 Cu/TiB
2 composite was fabricated with low cost TiO
2, H
3BO
3, Na
3AlF
6 powders and Al Cu alloy. TiB
2 particle is very small, about 0.93 μm in size, and it has spheric shape in the solidification microstructure of the composite. The distribution of TiB
2 particle in the matrix is uniform. The interface between TiB
2 particle and the matrix is combining well. The tensile strength, yield strength and elongation of the composite are 416.7 MPa, 316.9 MPa and 3.3%, respectively, when TiB
2 particle contenTin the matrix is 10 vol%.
