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。

As for coseismic deformation of Chi-Chi earthquake, the footwall of Chelungpu Fault moved southeastwards 0.3-1.5 m, and the value was increasing toward the fault; the hanging wall moved northwestwards 1.4-7.0 m, but the value was smaller south of the Choshui River. After the Chi-Chi earthquake, the hanging wall of Chelungpu Fault was still moving west-northwestwards and kept uplifting, while the footwall gradually changed direction from ESE to WSW or even WNW, clockwise resuming to inter-seismic deformation pattern. It is interesting to notice that despite the largest coseismic deformation in the northernmost segment of Chelungpu Fault, the post-seismic deformation peaked around the epicenter of Chi-Chi earthquake.

集集地震之同震变形，在车笼埔断层下盘向东南方向位移0.30~1.5 m，且越靠近断层位移量越大；车笼埔断层上盘则向西北方向大幅位移约1.4~7.0 m，浊水溪以南的位移量较小；集集地震以后之震后变形型态，以车笼埔断层为分界，上盘在震后向西北西方向位移的型态仍与同震时相同，下盘由同震时一致性的向东南东方向，逐步向西北西或西南西方向位移，亦即在车笼埔断层下盘有逐步依顺时针方向回归至震间的滑移型态；另就位移速率而言，虽然同震变形最大地区在车笼埔断层北端，但其震后的变形量最大地区，却集中於震央位置附近；就地震循环而言，震后的6年期间仍处於地层压密重整阶段，尚未回归至该区震间阶段的位移状态。

The results show that the alloy undergoes obvious plastic elongation, the specimen fractures into four sections and the diameter changes from 16 mm to 12 mm. The fracture surfaces distribute randomly well developed and partially developed veinal patterns. The deformation behavior of alloy is non-Newtonian flow behavior. About 3% amorphous matrix of extruded specimen transforms crystal, the crystal particles with size of 10-20 mm are precipitated in the amorphous matrix, the thermostability of the extruded specimen was lowered. The failure of the alloy is mainly attributed to non-uniform viscous flow under high strain rate resulting from the hydrostatic extrusion process.

结果表明：非晶合金在高应变速率下产生了明显的塑性变形，直径从16 mm变为12 mm，断裂为4段，且样品断口上随机分布着充分发展与未充分发展的脉纹式切变带，由此可看出非晶合金的变形为非牛顿体变形行为；挤压后的样品约有3％的非晶相发生晶化，在非晶基体上析出10～20 nm的纳米晶粒，导致挤压后非晶合金的热稳定性降低；静液挤压高应变速率变形条件使非晶合金产生非均匀流变，是造成非晶合金断裂的主要原因。
