Özet:

This study has studied the effects of traditional water supply and deep cryogenic processes and temperation processes on the microbuilding, hardness and shrinking power of AISI H13. For this purpose, the samples were used by traditional water-giving thermal process and deep cryogenic process at -196 °C. To determine the effects of the temperation process, samples were applied single temperation and double temperation thermal processes at a temperature of 560 °C for 3 hours. The microbuildings of the samples have been studied, the changes in hardness and impact energies have been determined. The microbuildings of the samples have been observed consisting of martensite, remaining esthenite and carbure particles.  With the deep cryogenic process, the remaining esthenite volume has been determined to be reduced and thin secondary carbure particles are formed. Similar hardness and impact energy values have been obtained in the samples applied to traditional water and deep cryogenic processing. Temperation has been observed a decrease in hardness values and impact energy values depending on heat operation.
