Kinetics of ordering in NiPt
- 45 Downloads
The kinetics of ordering for an almost equiatomic NiPt alloy were measured by X-ray diffraction. The measurements were carried out at the temperature of annealing between 390 and 570° C.
The results show that the transition from a disordered to an ordered state can be attributed to two processes: one is a nucleation of ordered zones and their growth and the other is a homogeneous ordering process. The latter is dominant at low temperatures (< 500° C) and nucleation-and-growth kinetics are dominant at higher temperatures.
