The results show that after quenched and tempered with protective coating,no elements in the protective coating are found to permeate into the matrix,but the martensite laths in welded zone and heat affected zone are refined and the dispersion of carbides in these area is increased,the sizes of the dimples in these fracture are decreased.

通常情况下，D406A钢壳体在热处理中未采用保护气氛，造成调质后壳体表面脱碳严重，使壳体强度降低。为防止或减少调质处理过程脱碳带来的不利影响，可采用保护涂料或保护气氛热处理以及真空热处理等[2]，但对于大型工件，采用保护气氛或真空热处理需要大量的设备资金投入；而采用保护涂料投入较少。

Addition of minor alloying elements can fine the structure of bainitic ferrite markedly. The bainitic ferrite is composed of subunits or subchunks. The carbides with different morphologies are distributed between the laths. inside the plates and at the boundaries of subunits. There are abundant fine structures in bainitic ferrite. In the primary bainite of Cu-Zn-Al alloy there are interfacial structure ledges.

结果表明：加入微量元素可以使贝氏体铁素体组织明显细化贝氏体铁素体由亚单元或亚块组成、碳化物形貌不一，分布在条间、片内和亚块边界贝氏体铁素体内有大量的精细组织。

There is an activation process for passivated alumina supported molybdenum nitride and carbides catalysts at the initial stage of hydrazine decomposition.

在肼分解反应初期，钝化态的氮化钼和碳化钼催化剂有一个活化的过程，随着启动次数的增加，催化剂的初活性逐渐提高，最后达到稳定。

The experimental results denoted that the finer pearlite along the austenite boundaries in the as-cast Cr30Ni20NRE steel disappeared first under long-term and high-temperature service condition, and that an umber of Cr- richened carbides were formed due to unila-teral carburizing at long-term and high- temperature, consequently causing Ni to concentrate, bulging and calalyzing decomposition of the carburizing gas.

试验结果表明，长期在高温条件下服役，铸态Cr30Ni20NRE耐热钢中沿奥氏体晶界的珠光首先融入奥氏体，长期高温单边渗碳形成大量富铬碳化物，促使镍富集并起泡形成瘤状物，催化含碳气体的分解；表层瘤状物使辐射管表层疏松，表面积扩张，加快了碳向基体的渗入，提供了碳化物持续长大的条件，并引起沿碳化物周边开裂和奥氏体基体严重萎缩；合金元素的重新分布造成主合金元素铬和镍产生两极分化，镍和硅的富集促使石墨化，与侵入的氧形成内部氧化空洞和膨胀疏松，最终导致构件穿孔失效。

This is believed to be conneeted with the depletion of Mo, a scavenger of P, in matrix due to the Mo tithed carbides formation during preaging. Therefore, more P is released and segregated to grain boundaries. Carbide coarsening perhaps contributed to the increment in transition temperature too.

Mo可抑制磷的偏析，但因时效过程中富Mo碳化物的生成和长大，使基体中Mo的含量降低，因此，磷从Mo的&束缚&下&解放&出来并偏析到晶界，使脆性转变温度升高，此外，碳化物的粗化也可能导致脆性转变温度升高。

Experimental results showed that the Me_3C pattern carbides produced by the action of catalyst and graphite are main carbon source to form diamond structure under high temperature and high pressure.

在高温高压条件下，金属触媒与石墨形成的碳化物Me3C是形成金刚石结构的主要碳源。

In as-cast microstructures, SG modification can refine austenites and inhibit their orientational arrangement, reduce and refine the intercrystalline carbides; in heat-treatment process, SG modification can either shorten the holding time or lower the holding temperature.

SG 变质处理能有效地抑制铸态组织中柱状晶的生长，细化奥氏体组织并降低其方向性，减少晶间碳化物数量并使之细化；对热处理组织，SG 变质处理可以加速碳化物溶解，缩短水韧处理的保温时间或降低水韧处理的温度。

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.
