Py. Lee et Cc. Koch, MICROSTRUCTURAL EVOLUTION OF NI40ZR60 ALLOY DURING EARLY-STAGE OF MECHANICAL ALLOYING OF INTERMETALLIC COMPOUNDS NIZR2 AND NI11ZR9, Materials chemistry and physics, 38(2), 1994, pp. 199-202
The microstructural change of Ni40Zr60 alloy during mechanical alloyin
g of mixtures of the intermetallic compounds NiZr2 and Ni11Zr9 has bee
n studied by transmission electron microscopy. A specific ''cauliflowe
r'' phase was formed during early stage of mechanical alloying process
. It is suggested that the solid state reaction between intermetallic
compounds NiZr2 and Ni11Zr9 is not the only origin for the formation o
f the ''cauliflower'' phase.
