碳化物

1."aragonite: an orthorhombic mineral form of crystalline calcium carbonate, dimorphous with calcite."

结晶富钙碳物的一种正交晶矿物,具有方解的两种晶态。

2.Although PM has solved the problem of carbide segregation and crassitude fundamentally, it has complicated technics and extortionate cost, so restricts its application.

粉末冶金虽然从根本上解决了碳物偏析和粗大的问题，但其工艺复杂，成本过高，应用受到限制。

3.Transformation mechanism of carbides and their effect on the stress rupture property were investigated in a Ni-base single crystal superalloy with microcontent of carbon.

研究了一种含微量(0.015%)碳的镍基单晶高温合金在热处理和持久过程的碳物演机制以及各种碳物对合金持久性能的影响。

4.The crack initiates at stress concentration point in the root of weld, where has much more martenite, carbide and inclusion, and the serious hydrogen segregation.

裂纹均在焊缝根部应力集处萌生，该处马氏体含量比较大，碳物及夹杂物较多，氢的偏聚现象严重。

5.The catalysts on studying can divide into two kinds: the transition metal bifunctional catalysts and the nitride, carbide and oxycarbide catalysts of transition metals.

目前,正丁烷脱氢异构可以分为两类,过渡金属双功能和过渡金属氮物、碳物和碳氧物。

6.It holds that main causes promoting crack on martensite stainless steel are gross martensite and crystal boundary carburet and secondary phase distributed along crystal boundary.

章认为，粗大的马氏体组织、晶界碳物以及沿晶界分布的“第二相”组织是促使马氏体不锈钢产生裂纹的主要原因。

7.It is proved that the pressmark of tooth root, the state of carbide and remanentelements in the material have different effects on the toughness of POwer hacksaw blades.

结果证明，机用锯条的分齿压痕、基体碳物状况以及材料的残存元素等对机用锯条的韧性有不同程度的影响。
