Resumo: Heat treatments for technological improvement of wood were made in the presence of air using Eucalyptus globulus. The heat treatment was made using an oven during 2 to 24 h and temperatures of 170 ºC, to 200 ºC. Mass losses increased with treatment time and temperature. Anti Shrinking Efficiency (ASE) between treated and untreated samples was calculated at 35%, 65% and 85% relative humidity for radial and tangential directions. Bending strength and MOE were also determined. Equilibrium moisture content of heat-treated wood decreased by 67%. 87%Radial ASE35% for Tangential ASE35% was usually higher than radial. ASE65% and ASE85% showed behaviour similar to ASE35% but smaller. All ASE values increased with temperature and treatment time. Bending strength and MOE decreased with mass loss.
