Phase composition and microstructure of materials in the Ir-Ru-B system prepared by arc melting and VHP sintering ×÷Õß:Zhou, XL (Zhou, Xiaolong)[ 1,2,3 ] ; Zhou, ZB (Zhou, Zhaobo)[ 1,2,3 ] ; Zhang, KH (Zhang, Kunhua)[ 4 ] ; Yu, J (Yu, Jie)[ 1,2,3 ] INTERNATIONAL JOURNAL OF MATERIALS RESEARCH ¾í: 108 ÆÚ: 5 Ò³: 378-389 DOI: 10.3139/146.111492 ³ö°æÄê: MAY 2017 ²é¿´ÆÚ¿¯Ó°Ïì ÕªÒª In this paper, materials in the Ir-Ru-B system with nominal compositions of Ir-Ru-2B and 3Ir-Ru-4B were synthesized by arc melting and vacuum hot press (VHP) sintering. The phase composition and microstructure were characterized using X-ray diffraction, back scatter electron imaging, energy dispersive spectroscopy and electron back scatter diffraction. Different preparation processes for these Ir-Ru-B system materials were studied. The results show that Ir-Ru-2B prepared by arc melting and VHP sintering contains Ir(Ru)B-0.9 and Ru(Ir)B solid solutions, while 3Ir-Ru-4B contains Ir(Ru) B-0.9, Ru(Ir)B-2 and Ir(Ru) solid solutions. The error for the lattice parameters of the VHP sintered samples was larger than that of the arc melted samples. The energy spectrum analysis of the Ir-Ru-2B samples prepared using different processes indicates that the solubility of the solid solutions in the VHP sintered samples was higher than the solubility in the arc melted samples. The formation mechanisms for the (Ir, Ru)-B, (Ir(Ru) B-0.9, Ru(Ir)B-2 and Ru(Ir) B) and Ir(Ru) solid solutions are discussed in detail. There is more Ir(Ru) solid solution in the VHP sintered sample than in the arc melted sample, and the grain orientation of the former is more complex than that of the latter. ¹Ø¼ü´Ê ×÷Õ߹ؼü´Ê:Vacuum hot press sintering; Arc melting; Ir-Ru-B system; Phase constitution; Microstructure KeyWords Plus:MECHANICAL-PROPERTIES; SUPERHARD MATERIALS; TRANSITION; DIBORIDES; NITRIDES; HARDNESS ×÷ÕßÐÅÏ¢ ͨѶ×÷ÕßµØÖ·: Zhou, XL (ͨѶ×÷Õß) [ÏÔʾÔöÇ¿×éÖ¯ÐÅÏ¢µÄÃû³Æ] Kunming Univ Sci & Technol, Dept Mat Sci & Engn, Kunming 650093, Peoples R China. µØÖ·: [ÏÔʾÔöÇ¿×éÖ¯ÐÅÏ¢µÄÃû³Æ] [ 1 ] Kunming Univ Sci & Technol, Dept Mat Sci & Engn, Kunming 650093, Peoples R China [ÏÔʾÔöÇ¿×éÖ¯ÐÅÏ¢µÄÃû³Æ] [ 2 ] Kunming Univ Sci & Technol, Key Lab Adv Mat Yunnan Prov, Kunming, Peoples R China [ÏÔʾÔöÇ¿×éÖ¯ÐÅÏ¢µÄÃû³Æ] [ 3 ] Kunming Univ Sci & Technol, Minist Educ, Key Lab Adv Mat Nonferrous & Precious Rare Met, Kunming, Peoples R China [ 4 ] Kunming Inst Precious Met, State Key Lab Rare Precious Met Comprehens Utiliz, Kunming, Peoples R China µç×ÓÓʼþµØÖ·:kmzxlong@163.com »ù½ð×ÊÖúÖÂл »ù½ð×ÊÖú»ú¹¹ ÊÚȨºÅ National Natural Science Foundation of China 51262015 State Key Laboratory of Advanced Technologies for Comprehensive Utilization of Platinum Metals SKL-SPM-201510 ²é¿´»ù½ð×ÊÖúÐÅÏ¢ ³ö°æÉÌ CARL HANSER VERLAG, KOLBERGERSTRASSE 22, POSTFACH 86 04 20, D-81679 MUNICH, GERMANY Àà±ð / ·ÖÀà Ñо¿·½Ïò:Metallurgy & Metallurgical Engineering Web of Science Àà±ð:Metallurgy & Metallurgical Engineering ÎÄÏ×ÐÅÏ¢ ÎÄÏ×ÀàÐÍ:Article ÓïÖÖ:English Èë²ØºÅ: WOS:000403331500005 ISSN: 1862-5282 eISSN: 2195-8556 ÆÚ¿¯ÐÅÏ¢ Impact Factor (Ó°ÏìÒò×Ó): Journal Citation Reports ÆäËûÐÅÏ¢ IDS ºÅ: EX6DA Web of Science ºËÐĺϼ¯ÖÐµÄ "ÒýÓõIJο¼ÎÄÏ×": 21 Web of Science ºËÐĺϼ¯ÖÐµÄ "±»ÒýƵ´Î": 0 ÒýÎÄÍøÂç 0 ±»ÒýƵ´Î 21 ÒýÓõIJο¼ÎÄÏ× ²é¿´ Related Records µ±ÓÐÈËÒýÓô˼Ǽʱ½ÓÊÕµç×ÓÓʼþ´´½¨ÒýÎĸú×Ù (Êý¾ÝÀ´×Ô Web of Science ºËÐĺϼ¯) È«²¿±»ÒýƵ´Î¼ÆÊý 0 / ËùÓÐÊý¾Ý¿â 0 / Web of Science ºËÐĺϼ¯ 0 / BIOSIS Citation Index 0 / Öйú¿ÆÑ§ÒýÎÄÊý¾Ý¿â 0 / Data Citation Index 0 / Russian Science Citation Index 0 / SciELO Citation Index ʹÓôÎÊý ×î½ü 180 Ìì: 0 2013 ÄêÖÁ½ñ: 0 ½øÒ»²½Á˽⠴˼ǼÀ´×Ô: Web of Science ºËÐĺϼ¯ - Science Citation Index Expanded ½¨ÒéÐÞÕý Èç¹ûÏ£ÍûÌá¸ß´Ë¼Ç¼ÖÐÊý¾ÝµÄÖÊÁ¿£¬ÇëÌṩÐÞÕý½¨Òé¡£ |
