氩气雾化René104镍基高温合金粉末的显微组织和凝固缺陷
氩气雾化 镍基高温合金 凝固组织 空心粉末
2019/3/5
采用氩气雾化制备René104(ME3)镍基高温合金粉末，对粉末的粒径分布、形貌、显微组织和凝固缺陷进行分析。研究结果表明：氩气雾化René104高温合金粉末氧含量较低，以球形和近球形为主；细粉收得率高，粒径小于75 μm的粉末达到70%。小于60 μm的粉末成分均匀，表面光滑，内部结构致密，具有典型的胞状晶组织。随着粒径的增大，粉末表面和内部开始出现树枝晶组织，显微组织为胞状晶+树枝晶；具有胞状...

索伦·克尔凯郭尔（Søren Aabye Kierkegaard，1813年～1855年），丹麦基督教思想家。存在主义的先驱。1813年5月5日生于哥本哈根，卒于1855年11月11日。早年在哥本哈根大学学习神学，因对理性哲学特别是黑格尔主义的批评而著称。其哲学主旨在于以个人生活的体验论证个性原则和对上帝的信仰。他认为存在就是由痛苦、烦恼、孤独、绝望、情欲、热情等情绪构成的个人的存在...
Elastic and electronic properties of hexagonal rhenium sub-nitrides Re3N and Re2N in comparison with hcp-Re and wurtzite-like rhenium mononitride ReN
Elastic electronic properties Re2N in comparison
2010/11/23
Very recently, two new hexagonal rhenium sub-nitrides Re3N and Re2N, which belong to a rather rare group of known metal-rich (M/N > 1) nitrides of heavy 4d,5d metals, have been successfully synthesize...
电渣重熔连续定向凝固René88DT合金的组织与热变形行为
电渣重熔连续定向凝固 热变形 动态再结晶
2013/9/29
自行设计开发了适合工业化生产高纯净,低偏析,无宏观缺陷铸锭的电渣重熔连续定向凝固技术(ESR-CDS)的设备和工艺,利用该技术成功制备了直径为Ø150mm的René88DT合金定向凝固铸锭。采用XRD测试了定向凝固柱状晶的生长取向,结果表明,ESR-CDS René88DT铸锭柱状晶择优生长方向为<100>系晶向;ESR-CDS铸锭与传统ESR铸锭相比,枝晶组织生长方向保持一致,二次枝晶...

PM René 95合金涡轮盘等温锻造工艺的模拟式设计
PM René 95合金 等温锻造
2008/9/19
利用热力耦合有限元程序FORMT,对PM René 95合金中等尺寸(外径尺寸约为630 mm)涡轮盘的等温锻造工艺进行了模拟式设计.结果表明,采用TZM钼基合金模具,在1050℃以接近10-3s.的应变速率进行闭式模锻和开式模锻,模具材料均能满足使用要求,且开式模锻设备最大载荷不超过31×103kN;采用K21合金模具,在1000℃以相同条件等温成形,模具材料因变形热效应及边界摩擦引起温升而失效...
REN-1000A型化学发光定氮仪的维护与管理
化学发光定氮仪 REN-1000A型
2008/5/9
REN-1000A型化学发光定氮仪器可测量固体、液体和气体中的总氮含量，符合ASTMD4629方法的要求，已成功的用于测定原油、馏份油、石油气、塑料、石油化工产品以及食物和水中的总氮含量。由于省去繁锁的电化学池子的操作和维修，简化操作，省去氢气，避免可能发生燃烧爆炸的危险而公认为是当前较灵敏、准确、快速、简便的方法。本文就如何维护与管理该仪器提出一些观点和看法。
