Özet:

 This research investigated the effect of cryogenic treatment on the notch impact strength, wear behaviour, microstructure, and hardness of AISI D2 steels. The study aimed to determine the impact of chemical composition and cryogenic treatment process on the materials mechanical properties. The samples prepared in the research were subjected to cryogenic treatment four times 12-48 hours at -145C and -196C after heat treatment to achieve the desired mechanical improvement. Afterward, the specimens were tempered for an hour at two different temperatures, 200C and 520C. After cryogenic treatment, microhardness, microstructural investigations, wear, and notch impact tests were conducted and compared with the untreated material. Under optimum conditions, the cryogenic treatment caused a maximum increase of 4 in the microhardness of AISI D2 steels. After notch impact tests, the fracture energy of the material decreased at different rates in all groups except for the tempered sample with a holding time of 12 hours. Following cryogenic treatment at -196C for 12 hours and then tempering at 520C for 1 hour, the wear resistance of specimen D11 increased by up to 88.
