The essential difference from binary systems is the need to specify tie-line information. Tie-lines are isothermal lines that connect the concentrations of the two phases in two phase regions of the 3-D ternary phase diagram, for example for the liquid and solid. The concept of tie lines need not be geometrical however. With the help of a special heat treatment a nearly hysteresis-free phase transition occurred in a Ti-51 at % Ni alloy. The size of the hysteresis is determined by the interfacial energies of the phase boundaries and these will be big, if the E-modulus and the lattic distortion are big. Effect of mechanical vibration, heat treatment and Furthermore, new metallic materials can be produced from metallic amorphous materials by proper crystallization processes, usually heat treatment, to meet the various industrial demands. In subvolume A, 8327 points of formation data of 1532 ternary amorphous alloys consisting of 351 ternary systems have been extracted, classified and evaluated. γ′ Phase Stability and Phase Equilibrium in Ternary Co-Al-W at 900 °C.

Acta Materialia. methods use transformation of intermediate phase to desired perovskite phase by a heat-treatment and two-step methods use chemical reaction of PbI 2 film with MAI solution followed by heat-treatments. The ternary phase diagram with vertices of MAPbI 3, This decrease occurred because the Mg-rich phase continuously impeded heat transfer at the grain boundaries. For the ternary Al alloys, when 0–1 wt% Fe or Cu was added to Al–10Si, the thermal conductivity increased slightly from 154 Wm−1 K−1 in Al–10Si to 162.7 Wm−1 K−1.
The nucleation of the Cu-rich phase was detected and its growth was studied. Changes in the Ag-rich phase were observed in situ by X-ray diffraction under vacuum. The heat treatment was conducted at different maximum temperatures up to 450 °C and the resulting particle product was analysed.
