Abstract The significance and limitations of the freezing diagram are discussed in terms of experimental observations reported in the literature. A freezing diagram constructed for the Cu-Ti system is shown to be an accurate predictor of metastable phase formation when the position of the T 0 lines are known. Freezing diagrams also enable the construction of qualitative continuous cooling transformation diagrams for all alloy compositions, and these help in understanding the microstructure produced after cooling at a range of rates. The diagram further enables a prediction to be made of the subsequent crystallization of quenched-in glass or the decomposition of metastable phases, and this is verified by experimental observation. Liquid phase separation also is discussed in terms of freezing diagrams, and it is found that a reported case of liquidphase separation is more accurately described as primary crystallization resulting in liquid stabilization.
