Sažetak
For economical production of die castings it is of great importance to ensure high quality of die manufacture and long working life. The repair or replacement of a die has a high cost in time and money. Dies for aluminium alloys die-casting fail because of a great number of a different and simultaneously operating factors. Die design, material selection, and thermal stress fatigue due to the cyclic working process, as well as to low and inhomogeneous initial die temperature contribute to the failures and cracks formation on/in dies. In the presented work the intensity and homogeneity of the temperature fields on the working surface of the testing die were checked through thermographic measurements, and failures and cracks on the working surface of the die were analysed by the non-destructive metallographic examination methods.
