The diagram consists of two single-phase fields separated by a two-phase field. The boundary between the liquid field and the two-phase field in Fig. 3 is called the liquidus; that between the two-phase field and solid field is the solidus. The Al-Ni-Ti system was evaluated by [82Nas]. This evaluation includes additional information from [78Ans], [83Sri], [83Zak], [85Omal], [85Oma2], [85Nas], and [86Edm].

The binary phase diagram shown for the copper-nickel alloy indicates that these materials can form both liquid and solid solutions over the full range of composition from Cu to Ni. Above 1728 K, the melting point of pure Ni the alloys ar in the liquid phase. Between 1728 K and 1357 K (the melting point of Cu) the alloys can be either solid or ... Nickel titanium, also known as Nitinol, is a metal alloy of nickel and titanium, where the two elements are present in roughly equal atomic percentages.Different alloys are named according to the weight percentage of nickel; e.g., Nitinol 55 and Nitinol 60.It exhibits the shape memory effect and superelasticity at different temperatures.. Nitinol alloys exhibit two closely related and unique ... The nickel-titanium phase diagram is shown in Fig. 1. The NiTi equiatomic compound undergoes a martensitic transformation. The martensite phase is soft, has a monoclinic structure, and exhibits the shape memory effect. In addition, the heat of reac-tion for the formation of NiTi is high enough for the CS reaction to take place. Titanium solubility in the δ-phase increases gradually as nickel is replaced by ruthenium. The upper titanium border of the δ-phase in the ternary Ti-Ni-Ru system connects the points of the 50Ti-50Ni alloy and the 45Ru-55Ti alloy of the Ti-Ru binary system, corresponding to the maximum titanium solubility in Ti-Ru at subsolidus temperature ...
