Popis: In situ 4.9wt.%TiB2/2024 composite has been successfully prepared by displacement reaction and spray deposition technique, and its microstructure and wear behavior were investigated. Experimental results have shown that in situ TiB2 particles uniformly distributed in the matrix, and the grain size of the composite was smaller than that of the alone 2024 alloy. Compared to the 2024 alloy, the composite showed accelerated aging process after solutionizing at 768K. The wear resistance of the composite improved considerably and a maximum wear resistance were obtained after over aging.
