What bond is Fe3Al, covalent, ionic, or metallic?
Weegy: Effect of adding carbon nanotubes on stress of Fe3Al intermetallics PANG Lai-xue(???)1, ZHANG Jin-sheng(???)1, XU Jing(? ?)1, SUN Kang-ning(???)2 1. Department of Civil Engineering, Shandong Jiaotong University, Ji’nan 250023, China; 2. [ School of Materials Science and Engineering, Shandong University, Ji’nan 250061, China Received 7 July 2008; accepted 29 October 2008 Abstract: Analyses on the stress in the carbon nanotube/Fe3Al composites were performed. The biphase interface valence electron structure was established on the basis of Pauling’s nature of the chemical bond. The stress occurs by the huge interface electron density difference, which will block the Fe3Al grain agglomeration and growth. With the X-ray diffractions, the calculated magnitude of compressive stress existing in the CNT/Fe3Al interface is 0.38 GPa. The experimental result verifies that the stress has a positive effect on the enhancement of mechanical properties of composite. Key words: interface stress; CNT/Fe3Al composite; interface valence electron structure 1 Introduction Iron aluminide (Fe3Al) is a very important structural material, and has been applied in varied fields such as power plant, tribological and electrical components[1-3]. Recently, a few studies have been carried out to utilize carbides or borides as reinforcements in iron aluminides via a powder metallurgy process[4-5]. Ceramic particles can be utilized as reinforcement to improve the high-temperature strength of intermetallic alloys[6-7]. Carbon nanotubes(CNTs) are new allotropic carbon materials with excellent mechanical, electrical, thermal properties, and chemical stability. It is widely perceived that CNTs will allow the construction of composites with extraordinary mechanical properties. Incorporation of these one-dimensional nanostructured materials into ceramics[8-9], metal[10-11], polymer[12-13] has attracted interest of researchers in recent years. However, less study concerned the fabrication and ... (More)
