研究结果表明:高温热压后的板材吸湿性降低,尺寸稳定性好,但热压温度过高会产生木材热分解,冲击强度略有降低。
The results showed moisture adsorption of the platen dried veneer was lower and its dimensional stability was better, but its impact strength dropped when pressing temperature was too high.
并对大型钢锭浇注的热环境进行模拟,考察涂料高温强度的变化情况。
And a large steel ingot casting simulation of the thermal environment to study the changes in coating high temperature strength.
热疲劳抗力主要取决于材料的高温屈服强度,在强度、塑性及循环热稳定性取得适当配合时最大。
The thermal fatigue resistance mainly depends on the high temperature yield strength and will become maximum, if the strength, plasticity and cycle thermal stability are in an adequate combination.
