| Abstract | The microstructure of cold sintered blocks formed on the mechanical alloying (MA) of NiAl-TiB2 have been investigated by means of transmission electron microscopy (TEM). The results reveal that the blocks consisted of beta-NiAl with a B2 ordered structure and TiB2, Al2O3 particles in addition to other metastable phases. The distribution of the phases and good bonding between them suggest that a sintering process occurred in-situ at low temperature in the later stage of the MA. The observed high density of dislocations and strong reaction between these dislocations and ceramic particles can explain the good toughness and high microhardness of the block. Minor crystalline and amorphous metastable phases have been found. A cold-sintering mechanism to form the block based on the metastable phase distribution has been proposed. |
