摘要
Using a depth sensing indentation (DSI) technique, the Martens hardness HM, indentation modulus E-IT and deformation work W for Al matrix and Al4C3 particles have been measured on mechanically 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 E-IT, comparable with Young's modulus is 2.5-5 times higher for particles than that for matrix. (c) 2005 Elsevier B.V. All rights reserved.
