查询词典 austenite

Bainitie carbide nucleates at the phase interface of γ/αand grows towards austenite and the subunits of bainite ferrites, which is a diffusion transformation of carbon atom along the phase interface of γ/.

钢中贝氏体碳化物在γ/α相界面上形核，向奥氏体中和铁素体亚单元间长大，是碳原子沿着相界面扩散的过程。

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。

Cr13 and Cr18Ni8 series stainless steels would be used for ship parts in the past,the former being poorly resistant to seawater and the latter being insufficient in the strength.In view of this fact,the seriated forrite-austenite dual steels with high strength and good resistance to seawater have been developed.

以前C，r13和Cr18Ni8系列不锈钢被用于制造船体零件，前者在海水中的耐蚀性不良，后者强度性能不够高，于是发展了既具有高强度又耐海水腐蚀的铁素体-奥氏体系列双相不锈钢，用于制造高速船的船体钢板、锻件(舵轴、舵柱、舵梢、尾轴、中间轴等)和铸件(螺旋桨、阀体、耐蚀叶轮等)。

Ammonia pressure meter is a special meter for ammonia, used to measure various non-crystallized and solidified medium that have no corrosive action on common carbon system steel, alloy structural steel, Austenite stainless steel, or tinsel bar solder, principally applicable for measuring pressures of liquefied ammonia, gas, or other mixtures in cooling equipments in chemical fertilizer production.

简介 氨压力表为氨专用仪表，用于测量对普通碳钢、合金结构钢、澳氏体类不锈钢及锡铅合金钎焊料无腐蚀作用，非结晶和凝固的氨气、氨液介质的压力。主要适用于化肥生产过程中设备或其他中用来测量氨的液体、气体或其混合物等的压力。

The presence of austenite at any 10% would causeloss of strength of both steels about 10 kg/mm~2, however, their toughness mightbe actually improved by these softer austenites formed along the boundaries oflath martensite.

回火奥氏体的存在使强度下降，估计10％的奥氏体使强度损失约10kg/mm~2。但较软的回火奥氏体沿板条状马氏体边界形成改善钢的韧性，使冲击韧性a_K提高。

Results of EBSD show that most of the reversed austenite in the steel treated by QT distribute along the grain boundary, but in the steel treated by two--phase region heat treatment the austenites distribute uniformly along all kinds of boundaries, especially also along the lath martensite boundary in the grain, so the cryogenic toughness can be also improved even the amount of austenitic is lower than that in the steel treated by QT process.

EBSD结果则表明：经两相区处理，回转奥氏体不仅在晶界和板条束界形成，也在晶内的板条界上形成，因此即便在其含量低于淬火+回火处理的条件下， 9Ni钢的低温韧性也有明显提高，证明回转奥氏体的分布也是影响9Ni钢低温韧性的一个主要因素。

Two separate tempering treatments at 670 ℃ is the most effective way to eliminate residual austenite in the carburized layer of steel.

该钢渗碳后于670℃回火两次是消除渗碳层中残余奥氏体的最有效方法。

To avoid the forming of cracks in iron based laser cladding, the volume fractions of austenite and cemetite in cladding layers were adjusted through adjusting the contents of Ni. The claddings were produced on gray irons without preheating.

采用铁基熔敷材料，在不预热情况下通过调整熔敷金属Ni含量，改变铸铁激光熔敷层内奥氏体相与渗碳体相体积分数，进而抑制熔敷层裂纹的产生。

The JIC is 0.1513 and the AK is 120.5 respectively. The scanning electron microscope and transmission electron micrograph shows that microstructure of the fracture toughness of new tiny deformation steel (GDL-1) was bunchy bainite+ martensite and a little retained austenite mixed structure. The retained austenitic film separates bunchy bainite into extra-fine subunits and improves the micro-ductility of the steel.

扫描电镜和透射电镜分析表明，空冷后新型高强韧GDL-1钢的显微组织为窄束状贝氏体＋马氏体和部分残余奥氏体复合组织，残余奥氏体以薄膜形态分割贝氏体板条而形成超细化亚单元，增加了材料的微观塑性。

Additionally Secondary carbide was dispersed after finishing austenite change, the while cast iron properties were fully improved.

再加上充分奥氏体化后的二次碳化物弥散析出分布，白口铁性能得到了根本的改善。

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。

Maybe they'll disappear into a pothole.

也许他们将在壶穴里消失
