均质合金

If this alloy is homogenized at 700℃ for 6h and slow cooled, the structure is that of large grains of α with twins, surrounded by coarse α+δ eutectoid.

这个合金如果在700℃均质化6小时，它的结构成为大颗粒的α孪晶相，周围包裹着粗糙的α+δ共熔相。

Research works of this thesis aims at the light magnesium lithium alloys and mainly focuses on the effects of the misch metal and some thermal treatments such as the homogenizing treatment 、 the hydrogenating treatment etc.

本论文以轻质镁锂合金材料为研究对象，以均化处理、氢化处理等热处理手段和混合稀土对Mg-Li-Zn-Zr系镁合金的显微组织和机械性能影响为主要研究内容，以具有代表性的Mg-7。

Its rapidsolidification behaviour during recalescence was studied by means of high speed cinematography andrapid infrared pyrometry,It is found that interface heterogeneous nucleation takes place in preferenceto homogeneous nucleation even at an undercooling above the previously accepted critical undercool-ing 0.2T_mfor homogeneous nucleatio...

采用高速摄影及快速红外测温技术研究了深过冷熔体的快速凝固行为。发现尽管过冷度超过了以往认为的均质形核临界过冷度0.2T_m，但是 Ni-32.5%Sn 共晶合金仍然优先发生界面异质形核，再辉过程中瞬时凝固速度最大可达784mm/s。

When the vials are full of Ar with previous vacuumize, the final milling product is disorder nanocrystalline Fe-Cr solid solution with ferromagnetism similar to the bulk alloys.

球磨50h，形成了bcc结构的顺磁性纳米晶Cr-Fe-V合金。在富Cr的合金成份内，Fe含量越高，生成均质的纳米晶Fe-Cr-V合金所需的球磨时间越长。

I urge any American living outside the country to get an early start checking his/her registration and receiving an absentee ballot, because it can take a while.

我奉劝身在国外的所有美国人早点着手核对登记表，并接收缺席选举人票，因为这得花点时间。
