您要查找的是不是:
- By spheroidizing, the lamellar pearlite can be transformed into nodular pearlite. 球化退火可使片状珠光体变成球状珠光体。
- It was discovered for the first time that spray formed UHCS part with lamellar pearlite structure possesses superplasticity without any thermal and/or mechanical pretreatment. 利用喷射成形的快速凝固的特点,有效地避免了超高碳钢中碳的偏析问题。
- In general, the strength of carbon steel containing lamellar pearlite is higher than that of carbon steel containing nodular pearlite, but the ductility of the former is lower than that of latter. 答:一般地,片状珠光体的强度高于粒状珠光体、塑性低于球状珠光体。
- fine lamellar pearlite structure 细片状珠光体组织
- Keywords bearing steel;accelerated cooling technology;fine lamellar pearlite;network carbide; 轴承钢;快冷工艺;细片状珠光体;网状碳化物;
- Atomic Force Microscope Technology for Measurement of Thickness of Lamella Pearlite 测定珠光体片层间距的原子力显微镜技术
- fine lamellar pearlite 细片状珠光体
- coarse lamellar pearlite 厚层状珠光体
- lamellar pearlite 片状珠光体,层状珠光体
- Its microstructure is fine pearlite and carbides. 它的微观结构是细珠光体和碳化物。
- Having the form of a thin plate or lamella. 薄片形的有薄片或鳃瓣状形体的。
- There is not lamella in the ingot. 钢锭没有明显的片层状组织。
- The results show that small Cr addition in steel can decrease the lamellar spacing of pearlite, and markedly increase strength and hardness with almost the same ductility and toughness, and accordingly improve wear and shelling-resistance of wheel steel. 实验结果显示,加入微量的铬,可以细化珠光体的片层间距,在保持韧塑性基本不变的情况下,显著增加材料的强度和硬度,从而提高车轮钢的耐磨性和抗剥离性能。
- The result indicates that temperature A1 goes up as the Al content increases, while lamellar distance in pearlite phase transformation macrostructure decreases and the network carbide decreases. 结果表明,随铝含量增加,A1温度升高,珠光体相变组织片层间距减小,网状碳化物减少。
- Microstructure of working layer in the barrel: pearlite or tempered sorbite. 辊身工作层金相组织为:珠光体或回火索氏体。
- The result is a patchwork mosaic of bone without an even lamellar structure. 结果形成了不均一的板层结构的骨的不协调嵌合体。
- For example turfy earth pearlite of 85 % + vermiculite of 10 % + 5 % . 例如泥炭土 85%25+珍珠岩10%25+蛭石5%25。
- The lamellar complex disintegrate and protrude outward to form the spike. 棘突由片层复合体衍生物汇集并延伸而成。
- At 12 weeks, the frozen mandibles and ilia had formed lamellar bone. 12周时冷冻骨及髂骨皮质形成较成熟的板层骨。
- The finer the pearlite lamella, the thinner the ferrite and the cemetite, the more the boundary between the ferrite and the cemetite, the higher the mechanical properties of the higher carbon steel. 珠光体片层间距减小,铁素体、渗碳体变薄,相界面增多,高碳钢的强、硬度提高;
