Purpose: The aim of this work was to show possibilities and conception of more accurate structure and mechanical properties forecasting with use of modified derivative -gradient thermal method. Design/methodology/approach: The main restriction in standard thermal and derivative analysis is one point measurement of temperature in casting with assumed geometry. In this work a modified method is described in which restrictions present in TDA method are overcame and more accurate diagnostic of the liquid material can be conducted. Findings: Structural relations have been shown for local conditions of solidification defined by two derivatives dT/dt and dT/dl. Presented method incorporates up-to-date knowledge about structure influence on operating properties of metallic materials. Research limitations/implications: Proposed methodology can be used for cast matrix composite and alloys properties diagnosis and forecasting. However accurate forecasting requires more detailed mathematical description. Originality/value: Proposed conception enables possibility of structure and operating properties forecasting basing upon one physical measurement - temperature measurement.
