Thermal fatigue wear is a kind of degradation, which characterises the metallic element friction surface of some couples, like forging dies, fire guns, heavy-duty mechanical brakes, etc. During the drop forging process, the die surfaces are heated. Because this heating has a variable or almost cyclic character, the thermal stresses and strains effects are similar to that, which characterise the low cycle, fatigue. The paper presents the experimental results concerning specific aspects, which characterise thermal fatigue wear of the steels used in forging dies construction e.g. equations which emphasise the cyclic durability and cyclic strengthening or softening phenomena of the die steels. These data can be used both in designing and exploitation of the forging dies.
