WebThe liquidus curve for the Mg-Pb system was redetermined, and its slope was used to assess phase transformations in theβ' + Pb-rich liquid phase field. A peritectic reaction occurred at 538.7 °C when Mg2Pb decomposed into a Mg-rich liquid andβ' (a Mg-Pb compound containing 35.15 at. pct Pb, or 0.3515 NPb, the atomic fraction of Pb) which …
Web31. jan 2011 · Cu–Zn is an important binary alloy system. In the interested temperature range from 300 to 1500 K, there are eight phases, liquid, Cu, β, β′, γ, δ, ϵ, and Zn phases. The thermodynamic descriptions of the Cu–Zn system are reassessed using the CALPHAD method. A new description of liquid phase and simplified description of body-centered ... WebWhat is peritectic phase diagram? Peritectic point – The point on a phase diagram where a reaction takes place between a previously precipitated phase and the liquid to produce a new solid phase. When this point is reached, the temperature must remain constant until the reaction has run to completion. A peritectic is also an invariant point.
