Abstract :This study aimed to analyze the possible changes in the pressure resistance values parallel to the fibersinsert ignore into journalissuearticles values(CS); by subjecting heat-treated wood to sub-zero temperatures. Within the scope of the study, test specimens were first prepared by applying thermowood heat treatment at 190 and 212 °C for 1 h to samples of wild service tree wood insert ignore into journalissuearticles values(Sorbus torminalis);. Both the heat-treated samples along with untreated control samples were then kept at -80 °C for 6. 18 and 54 h to obtain the test specimens. When compared to the control samples. Test results showed a difference in the parallel fiber pressure resistance of the heat-treated test specimens held at -80 °C and the values were seen as very positive, especially with the 6-h and 18-h applications. The CS resistance values of the control samples and the heat treated samples as N/mm 2 at 190 and 212 °C for 1 h were respectively 56.12, 69.28 and 62.12 for initial; 51.38, 73.25 and 80.55 for 6 h; 50.31, 72.82 and 75.66 for 18 h; 55.85, 60.19 and 62.14 for 54 h.
