The results show that the main reason is many little cracks exist,and heavy reticulation structure,inclusion, coarse grain and side decarburized stucture.
结果表明,其发生断裂的主要原因是存在较多的小发纹,加之较严重网状组织、夹杂物、晶粒粗大和边部脱碳组织,在机械加工力的共同作用下,导致轻轨发生断裂。

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。
