Die-casting is the most cost efficient and technical easy method of casting sophisticated and accurate aluminium alloys parts in great-scale series. Aluminium alloys die-castings require little machining prior the final installation. Die-casting dies for casting of aluminium alloys fail because of a great number of different and simultaneously operating factors. Die design, material selection, and thermal stress fatigue generated by the cyclic working process, as well as to low and inhomogeneous initial die temperature contribute to the failures and cracks formation on/in dies for die-casting of aluminium alloys. In the frame of the presented investigation work the intensity and homogeneity of the temperature, fields on the working surface of the testing die were checked through thermo graphic measurements, and failures and cracks on the working surface of the die were analysed with nondestructive metallographic examination methods.
