Highlights The structural behaviour of deformed kaolin was investigated extending up to 1500 °C. The deformation was induced by innovative ball milling. The mechanical energy transfer to the material was measured via the microstrain. Microstrain influenced the thermal behaviour in two different regimes. The two different regimes can be exploited in the industrial use of the material.
