Left: Equilibrium compositions \(\mathrm {X}_{\alpha _{\text {s}}}\), \(\mathrm {X}_{\beta }\) and \(\mathrm {X}_{\text {liq}}\) resulting from slow cooling rates \({|{\dot{T}}|\! \ll \!|{\dot{T}}_{\alpha _{\text {m}}, \text {min}}|}\), such that \(\mathrm {X}_{\alpha _{\text {m}}}=0\). The experimental data is based on Katzarov [28], Kelly [4], Malinov [20] and Pederson [35]. Right: Metastable (pseudo-) equilibrium composition due to Martensite transformation for \({|{\dot{T}}|\! > \!|{\dot{T}}_{\alpha _{\text {m}}, \text {min}}|}\), such that \(\mathrm {X}_{\alpha _{\text {s}}}=0\)
