Abd-Elhady, Gordon Sargent] Three Ni2Cr alloys, with phosphorus (P) contents of 0.002, 0.017 and 0.078 wt % were prepared as cast slabs, which were then thermomechanically treated to a final thickness of 0.38mm, after which they were solution annealed at 900° C for 1 h and water quenched. The isothermal order-disorder transformations of the Ni2Cr alloys were investigated in specimens aged at temperatures between 425 and 550° C, for times ranging from 2 h to 70 days, by surface hardness measurements and microstructural studies. From the surface hardness data, time-temperature-transformation (TTT) curves were constructed for each of the three alloys of different phosphorus content. It was found that increasing the amount of phosphorus greatly reduced the time required to start and complete the order transformation. However, it was found that the effect of phosphorus content on the rate of transformation was significantly reduced at ageing temperatures above 500° C. The results are discussed in terms of models for nucleation and growth of ordered phases. Chapman and Hall Ltd, 1986 Abd-Elhady M.
