查询词典 carbides

Various kinds of steel such as structure steel, tool steel, pipe line steel, reinforcing steel bar, common engineering steel and cast iron may be improved in their properties by vanadium nitrides and carbides.

已有的研究表明碳氮化钒添加于钢中能提高钢的耐磨性、耐腐性、韧性、强度、延展性和硬度以及抗热疲劳性等综合机械性能，并使钢具有良好的可焊接性能，而且它能起到消除夹杂物等作用，在高强度低合金钢中的应用效果更加明显。

Improvement and modification of traditional metal sulphide catalysts, and the current situation of new catalysts such as metal carbides, metal nitrides and metal phosphides are emphasized.

着重概述了传统金属硫化物催化剂的改性方法，新型的金属碳化物、金属氮化物和金属磷化物催化剂的研究现状。

And the strengthening mechanism can be described as follows: WC cemented carbides have interlaced short-clubbed grain, and in the bend strength test, the microcrack generates at WC/WC grain boundary, and may be blocked by interlaced fine-clubbed grains during extending, which induce the intergranular pulling-out. Due to the pulling-out mechanism, fracture-extend energy is greatly expended, thus bend strength is increased. The wear mechanism is groove wear and spalling of WC grains.

热机械合金化合成的WC-Co硬质合金比传统方法制备的同类WC合金具有更高的强度，其机理是：热机械合金化合成的WC合金具有交替排列的短棒状组织，在三点弯曲试验中，微裂纹萌生于WC/WC晶界位置，受到交错排列的短棒状晶粒的阻碍，裂纹扩展以短棒状晶粒的拔出方式进行，极大地消耗了裂纹扩展的能量，从而提高了弯曲强度；合成试样的摩擦磨损过程以犁沟磨损和WC颗粒的剥落为主要特征。

The influence of secondary carbides precipitation and transformation on hardening behavior of a 14Cr-1Mo-1.5V cast iron in sub-critical treatment was studied using optical microscope, transmission electron microscopy and X-ray diffraction.

为了揭示高铬耐磨铸铁硬化的微观机制，提高其使用性能，采用光学显微镜、透射电镜和X射线衍射研究15Cr-1Mo-1.5V高铬铸铁中二次碳化物的析出和转变对其亚临界处理硬化行为的影响。

But we don't care about Battlegrounds.

但我们并不在乎沙场中的显露。

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
