Özet

This study describes the effect of heat treatment on the some of the physical and mechanical properties of beech (Fagus orientalis Lipsky) wood at different temperatures and times. Samples of beech wood were heat-treated at 150, 175, and 200 degrees C for 1, 3 and 5 h. The mechanical properties of the heat-treated and untreated samples were determined by bending tests, modulus of elasticity in bending, compression strength parallel to grain, and Brinell hardness. Physical properties were determined by weight loss, density, and volumetric swelling tests. The results showed that the heat treatment increased the weight loss, density loss and dimensional stabilization. In addition, an increase was observed for compression strength parallel to grain (except for at 200 degrees C for 5 h), while a small increase was determined in the bending strength, modulus of elasticity in bending, hardness values of heat-treated wood samples at 150 degrees C for 1 and 3 h. However, the heat treatment at higher temperature and duration clearly decreased bending strength, modulus of elasticity in bending, and hardness.
