使成合金

Nd and Y showed more evident effects than Gd and La due to lower temperature of eutectic reaction with aluminum. In order to investigate mechanism of the formation of the intercellular dispersoid which is being in debate and possibility of suppressing the dispersoid, a nucleation kinetic model which including unsteady nucleation and effect of alloy element was established.

Al-Fe-Mo-Si-Zr-Ti合金粉末具有四种凝固组织，初生Al〓〓，α-Al与Al〓共晶，胞晶及显微胞晶，合金元素Mo的加入，显著提高合金粉末凝固前的过冷度，使10~40μm粉末的凝固机制发生了变化，由导热控制型转变成溶质扩散控制型，从而基本上消除了该尺寸范围内粉末凝固组织中共晶成分和初生相，但对大于40μm的粉末，因共晶区富Zr核心的优先形成而使Mo的作用效果不明显。

These results prove that iron ion or 4s conduction electron can produce new square atom loop 4L, magnetic moment of iron ion can be made by magnetic moment 2P(subscript m0k) of 2 4sEE in 4L loop, Curie temperature T is proportionate to quantized energy of 4sEE, HMCE can produce contrarotation or reverse self-rotation energy U(subscript 0K) and U(subscript 0K) can produce great thermoelecal potential.

这些结果证明铁离子或4s传导电子产生了新的正方形原子轨道4L，2个4sEE在4L轨道上产生的磁矩2P(下标 m0K)构成铁离子的磁矩，居里温度T与4sEE的量子化能量成比例，基金属传导电子产生了反向旋转或反向自旋能量U(下标 0K)，U(下标 0K)使合金产生大的热电势等反常物理量。

H2 has the tendency of accelerating synthesis. And the mechanism is that H2 can not only accelerate the refinedness of the powder particle of Ti, make the novel surface of fracture clean, but also enhance the activation of Titanium.

结果表明，在5种不同球磨环境下用Ti粉和活性炭粉都能合成TiC，其中在H2环境下的合成速度最快。H2对TiC的机械合金化合成具有加速作用，其机理是H2不仅能促使Ti与活性炭粉末细化，使断裂的新鲜表面保持清洁，而且能使Ti的活性增强。

In Figure 2 are shown the results of corresponding trials with steel containing somewhat larger amounts of alloying elements.

在图 2 中被用钢显示对应的审判结果包含某物比较大量的使元素成合金。

It is found that before the pearlitic and upper-bainitic reactions, a pro-cutectoid orpro-bainitic phase is precipitated along the austenite grain boundaries in the cyanidedsamples; and it is thought that this is likely a nitrogen-bearing phase which provides thephase boundary effect for the nucleation of the reactions and impoverishes the parentaustenite in alloy content, thus accelerating the transformation of austenite.

实验中发现，在珠光体及上贝茵体形成之前，氰化试样中均有一种过剩相沿奥氏体晶粒边界析出。这种先析相可能是一种含氮的化合物，其析出为珠光体及上贝茵体的非自发形核提供了现成的有利界面，并使奥氏体合金化程度降低，因而加速了转变。

The enhance nient of the corrosion resistance laser dadoling of the CNTs/Ni60 coatings is due to that the reserved carbon nanotubes in the coatings segregate the corrosive medium and promote N-based alloy passivation, the formed phases of the carbide and the reserved carbon nanotubes homogenous distribution in the claddings resist die corrosion.

碳纳米管／镍基激光熔覆层耐腐蚀的原因在于熔覆层保留的碳纳米管使熔覆层更加致密，隔离了腐蚀介质，促进了镍基合金的钝化，从而提高了熔覆层的耐蚀性；同时，熔覆层中保留下来的碳纳米管和被分解的碳纳米管与金属基体形成碳化物，作为增强相均匀弥散在熔覆层中，它们的存在阻止了腐蚀坑的长大，因而蚀坑较小，耐腐蚀性得到提高。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。

Galvanizes steel pallet is mainly export which suits standard packing of European Union, the North America. galvanizes steel pallet is suitable to heavy rack. Pallet surface can design plate type, corrugated and the gap form, satisfies the different requirements.
