Description:
The TiBe12/NiAl composites fabricated by a powder metallurgy technique were examined for the extent of interdiffusion between its components, using scanning Auger microscopy. The results revealed an evidence of a reaction between the two component intermetallics after annealing at 1300 K for 100 h, with a 95-micron reaction zone extending from the TiBe12/NiAl interface. The concentration profile across the reaction zone showed that the Ni, Al, and Be concentrations were in a 1:1:2 ratio, while Ti was present in only very small amounts.
