The results show that dynamic softening is easy to occur in these ingots and flow stress becomes steady finally; the material constants of hot deformation are procedural parameters that stress-level coefficient α, strain rate sensibility exponent m and deformation activation energy Q are all increased with strain increasing, while stress exponent n is decreased gradually; the values α and m of the alloy homogenized are the biggest and the value n is the smallest, dynamic softening effect of the alloy is the most obvious, which can deform evenly; influence of strain on the value Q of the alloy homogenized is a little and the average value of Q is only 176.5kJ/mol, so the alloy is easy to deform; the alloy matrix shows the regular recrystallization grains when the strain is 50%; dislocation cell structure re-formed in the grains with increase of strain.

结果表明：经不同处理的Al-1Mn-1Mg合金均易发生动态软化并最终呈现稳态流变特征；热变形材料常数是过程量，随应变量的增加，应力水平参数α、应变速率敏感性指数m和热变形激活能 Q 随之增大，而应力指数 n 则逐渐减小；均匀化退火后，铝合金的α和m值最大而n值最小，动态软化效果最明显且变形均匀，在该状态下，铝合金的 Q 值受变形量影响小，平均仅为176.5kJ/mol，易进行热变形；当应变量为0.7时，基体呈现规则的再结晶晶粒组织，随着应变量的增加，晶内重新形成了位错胞结构。

At the same time, some defects are pointed out: present fabrics are not properly applied, and most of looms can't produce woven perform whose property is similar in different directions. Their shearing strength are lower, utilization of mechanical properties are also smaller;Although three-dimensional braided composites is of excellent integrated structure, normal braided fiber is traveled from internal to external surface, which is passed through braider and becomes three-dimensional structure. If the external surface is cut or rubbed , it's possible for the fiber to break down. In addition , the shape of perform is easily changed after it's finished . To deal with respective shortcomings and highlight their own advantages, we're searching a new weaving method which is the combination between weaving and braiding .

但它们各自也具有许多缺点：目前机织物适应性不够，大多数织机还不能加工三维各向同性的机制预型件，材料剪切性能较低，力学性能利用率低；三维编织复合材料虽然具有良好的结构整体性，但常用的编织都是纤维从内表面穿到外表面，即穿过编织件的断面成三维结构，用这种方法制成的结构，如果外表面受到摩擦或切割损伤，就有可能导致结构的解体，此外编织结构的织物易变形，所以我们需要考虑一种新的结构，能同时发挥各自优势，又能同时克服二者缺点，这就是机织与编织结构相结合的方法。

Whether it or not to improve the lubrication and dynamic performance of gear, at the same time to realize a "green lubrication" type of gear transmission of low cost, energy saving and easy maintenance by means of making use of the frication material"s lubrication performance and meshed medium"s elastic deformation?

Equiaxed and bigger grains are produced after C.P.Ti is deformed under the high temperature. Besides, many tiny subgrains were found in some of the metallurgical structure. The dislocation reaction caused by the deformation under the high strain rate generates ductile cellular metastructures, while the equiaxed cellular metastructures are generated under the low strain rate. The metallurgical structure of TC4 alloy including lath-shaped hexagonal martensite and trimetric martensite only exists in the higher temperature. The homogeneous, tiny and reticular grain shown after extreme high temperature deformation.

在高应变速率下变形引起的位错反应形成拉长的胞状亚结构，而低应变速率下变形则形成等轴的胞状亚结构；TC4合金在特高温变形条件下其金相组织呈网篮状，显微组织几乎全部为均匀细小的晶粒，同时出现了板条状六方马氏体；在温度尤其高的情况下还形成了斜方马氏体，变形引起的位错反应形成六方位错网络，在1200℃以下的变形易产生孪晶。

And for the grommets in the shoulder strap, he has switched from copper, which is relatively soft, to hard engineering plastics such as Delrin, which retain their shape and hold up nicely under loads of over 100 kilograms.

因此他将最易因载重而脱线断裂的帆布背带，改为与降落伞安全带同级的尼龙带；衔接背带的扣环，也从较软的铜环，换成坚硬不变形的塑钢材质，即使长期承重上百公斤也不会损坏。

For thinner films, stacking faults are preferred in the scratch process, which increase storage capacity of plastic deformation in the film, and further inhibit the stick slip amplitude in the friction oscillation process. For thicker films, dislocation loops, which glide along slip plane downward to the grain boundary, dominate over the stacking faults, and finally dissipate on the grain boundaries. Since the intergrain stacking faults are inactive in thicker films, the stick slip phenomenon is similar to that in single crystal.

摩擦过程中易在较薄的薄膜表面和薄膜晶界之间产生穿晶层错，穿晶层错的产生增加了薄膜蓄积塑性变形的能力，从而抑制材料表面摩擦力在黏滑过程中的振荡幅度；在比较厚的薄膜中不易生成穿晶层错，在摩擦过程中位错环依次向体材料发射，并与晶界反应，湮灭于晶界，黏滑动摩擦响应与单晶相似。

Secondly, whether or hand-finished furniture for furniture, materials are wood, and forcing, Yi deformation or affected with damp surfaces, especially furniture Daixinban a system, there are serious environmental problems cause anxiety.

其次，无论是成品家具还是手工打制家具，材质都是木质，受潮及外力作用时易变形或开裂，尤其是大芯板打制的家具，还有严重的环保问题让人揪心。
