The decomposition of the metastable [MATH] phase in [MATH] Cez alloy has been studied during continuous heating up to 830°C. The heating rate varied between 0.25 and 5°C/s. Electric resistivity measurements, and hardness measurements revealed different phase transformations as temperature increased. Different samples were quenched from different temperatures during the heating range and were then studied by X-ray and TEM, allowing to correlate the changes in resistivity measurements to the beginning of the precipitations of the [MATH]and [MATH] phases and to establish the continuous heating transformation diagram. A change in the resistivity variations, not dependent on the heating rate was observed near 700°C. X-ray quantitative analysis and EAM studies revealed that the structure consisted of [MATH] maximal content of [MATH] phase, surrounded by [MATH] rich zones in the matrix. For temperatures greater than 700°C, the content of [MATH] phase diminished and the [MATH] phase was homogenized.
