“…Two grooves were machined to a depth equal to one-third of the radius of each log at 10 cm from the crosscut section in all logs, as recommend in the literature. [9,10,20,29]…”

“…[1,3,13,14,[16][17][18][19] When steamed at 54°C, the H. brasiliensis logs produce boards with higher end-cracks, where 704 and 239 mm are in their respective central and peripheral boards, whereas the steamed logs at 92°C present a greater relief of growth stresses, as observed by the smaller difference between the cracks' length in the central (394 mm) and peripheral (165 mm) boards. [20] The drying process is the best way to add value to the lumber. [3,4,19,21] Although some kinds of wood, among them Paulownia fortune, [22] Eucalyptus grandis, and Corymbia citriodora, [23] present low liquid and gas permeability, the rubberwood is a relatively fast-drying wood [24] due to its high permeability.…”

“…The board's cracks were smallest in the Hevea brasiliensis logs that reached the glass transition temperature logs when steamed for 36 h at a temperature of 54 °C, 75 °C and 92 °C (Pellozzi et al, 2014).…”

“…These defects result in great yield losses and, consequently, make the use of eucalyptus for sawn wood impracticable (Touza Vásquez, 2001;Calonego et al, 2010;Severo et al, 2010). Techniques that have been used to relieve the tensions arising from growth stress include heating the logs in water or applying saturated steam (Skolmen, 1967;Severo & Tomaselli, 2000;Juodeikiene & Minelga, 2003;Calonego & Severo, 2005;Rocha, 2011;Tan et al, 2011;Pellozzi et al, 2014).…”
