Abstract Using a depth sensing indentation (DSI) technique, the Martens hardness HM, indentation modulus EIT and deformation work W for Al matrix and Al4C3 particles have been measured on mechanical alloyed system Al-Al4C3. It has been shown that the hardness of Al4C3 particles (10-14 GPa) is 5-7 times higher than the hardness of matrix. Hard particles absorb 2 times more elastic deformation energy than the soft matrix. Indentation modulus EIT, comparable with Youngs modulus is 2,5-5 times higher for particles than that for matrix.
