This is important with hygroscopic materials but can also be essential for non-hygroscopic materials.

材料的预先烘乾不但对湿度敏感的材料很重要而且对非湿度敏感的材料也是必要的。

The deformation mechanism is mainly the single-slip and cross-ship, the fracture mechanism is mainly the congregation of transgranular micro-hole, and large uniform deformation occurred before tough fracture, and therefore, the ability of plastic deformation and the mechanical properties of the material were remarkably improved. These fully indicate that the new melt-treatment developed in this work is an effective and advanced technique, and further testify that the improvement of metallurgical quality of the material is the key to enhance its mechanical properties, especially its plastic deformation performance. The results of tensile and compression tests at elevated temperature also indicate that the suitable hot-working temperature range is 400～450℃. 4. A steady-state plastic flow exists during the plastic deformation of the aluminum sheet used for pressure can at elevated temperature. A hyperbolic sine relationship can be satisfied between the steady-state flow stress and strain rate by introducing an Arrhenius term which involves some thermal activation parameters, i.

压力罐用铝材中的主要冶金缺陷为Al〓O〓夹杂物、气孔及富Fe杂质相；高效熔体处理显著改善了材料的冶金缺陷的存在形态，使含杂量明显减少、夹杂物尺寸变细小且分布均匀，富Fe杂质相变为细小、分布均匀的团球状或短棒状的复杂化合物，同时也明显细化了结晶组织；此外，由于高效熔体处理有效地减少了材料中裂纹萌生源数量，因而改变了材料的塑性变形微观过程及断裂方式，主要以单滑移和交滑移进行塑性变形，断裂方式为穿晶微孔聚集型，韧性断裂前产生了大量的均匀变形，不易出现变形失稳，从而显著提高了罐用铝材的塑变能力和力学性能。

通过以上这种过程的研究，了解到：在传统造物中，人的生存和繁衍是取材造物的最根本出发点；材料的使用方法实际上是造物过程的一种表现，它以材料的本质特征和内在规律为基础；造物者的严谨精细的工作态度则是充分展示材料美感的技术基础。

The results of thermal property of DSC for PP composites show that two melting temperatures implied immiscibility for PP composites. The melting temperature and corresponding fusion heat for PP material was not changed by additives. Therefore, the immiscibility PP composites resulted in their poor mechanical properties.
