Webb31 jan. 2011 · It was found that when the initial melt undercooling (Δ T) is smaller than 130 K, the overall thickness of the peritectic phase formed in peritectic reaction (PR) and peritectic transformation (PT) decreases as Δ T increases. WebbFör 1 dag sedan · According to the BSE/EDS and XRD pattern of alloy a4 as shown in Fig. 2 a–b, the white phase λ 3 is the primary solidification phase. After the precipitation of λ 3, the liquid phase moves to the monovariant line and transforms into fcc(Co) + λ 3.At last, the composition of remaining liquid phase reaches the quasi-peritectic reaction liq. + λ 3 … WebbFurthermore, two peritectic reactions were observed and the course of liquidus lines was determined in the whole investigated composition range. The new phase diagram differs considerably from all previous versions, and, for the first time, gives a complete rationalization of the crystal structures observed in the debated composition area. cygwin dig command
