Abstract:
In this work, Ti25Cu75melt-spun partially amorphous alloy was used as a source of Ti and Cu to synthesizein-situ TiC-Cu nanocomposites. The reaction between the alloy and carbon started during ball milling andcontinued during Spark Plasma Sintering. At the same time, during ball milling, the alloy experiencedphase transformations: crystallization of the amorphous phase was followed by decomposition ofTiCu3. Copper crystallites formed during the alloy transformations were the reason for the presence ofcopper regions 0.5–1mm in size free from TiC nanoparticles in the sintered composites. The Ti-Cuintermetallics transformed into non-agglomerated TiC 10–20 nm in size distributed in the copper matrix.The hardness of the synthesized TiC-Cu nanocomposites exceeded that of composites obtained by con-ventional sintering of ball-milled Ti-C-Cu powders.
