查询词典 austenite

With the addition of Al of about 1 wt%, the proeutectoid cementites were restrained during equilibrium transformation and dynamic phase transformation, the stability of undercooled austenite during deformation was increased, retarding the formation of pearlite and the interlamellar spacing of pearlite was decreased.

Al的加入使动态相变过程中奥氏体的稳定性提高、珠光体转变推迟，进一步细化了珠光体片层间距。

结果表明经800℃-450℃等温处理后残余奥氏体体积含量最高达15.1%，并且有最高的拉伸强度995MPa，而经820℃-450℃等温处理后则有最高的延伸率20.0%和最大强塑积19400MPa%。

In order to measure the hardness of a special phase transformed in middle temperature from austenite,some 0 1mm thick pure iron sheets,nitrided at 640℃ and then isothermally treated at 225℃,were prepared for hardness test on the transverse section by using FM 700 micro hardness tester.

为了测定高氮奥氏体特殊的中温转变产物的硬度，用 0 1mm厚的薄片状纯铁试样于 6 4 0℃渗氮，获得高氮奥氏体，随后在 2 2 5℃等温至完全分解。

Minor Ce is found in pearlite and honeycomb ledeburite which transformed by the dendrite of primary austenite, while major Ce in ledeburite of lathy cementite type.

初生奥氏体枝晶转变形成的珠光体和蜂窝状莱氏体都含有较少的Ce，而板状渗碳体型莱氏体含Ce较多。

The evolution of pro-eutectic austenite in semi-solid high chromium cast iron was studied by self-made slope sampling plate through metallographical image analysis system.

采用自行研制的倾斜取样板进行取样，并借助金相图像分析系统研究了半固态高铬铸铁先共晶奥氏体的衍变过程。

If the RE/S ratio reached a critical value, namely about 4, not only the MnS inclusion is completely converted into sulphide and oxysulphide of RE, but also the prior austenite grain is remarkedly refined and their toughness is improved.

当RE/S达到临界比值(约为4)时，不仅使MnS夹杂物完全转变成稀土硫化物和稀土硫氧化物，而且使高温奥氏体晶粒显著细化，改善韧性。

The distribution of carbon atom in Fe-Ni-C austenite can be described quantitively with Monte Carlo method.

定量描述了Fe-Ni-C合金中碳原子的分布状态。

SEM observation shows alternative austenite and martensite striae at the surface of the NiTi SMA microtubes subjected to pure torsion.

在扭转载荷作用下发生相变时，其表面形成的片层结构分布较均匀，片层间距小。

When the steel changed in form between Ms and Md,its tensibility enhanced considerably due to s train-induced martensite transformations and transformation-induced plasticity of retained austenite.

该钢在Ms-Md温度之间形变时，应变诱导残留奥氏体向马氏体转变，使结构钢也能产生相变诱发塑性［3］。

The influence of untransformed austenite areas on the properties of austenitic-bainitic ductile iron is discussed.

该文用彩色金相技术显示了奥氏体—贝氏体球墨铸铁中未转变奥氏体区的组织，用定量金相研究了等温淬火温度和时间对未转变奥氏体区的影响，讨论了未转变奥氏体区对奥—贝球铁性能的影响。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。
