. Meanwhile, with the addition of small amounts of boron, the ductility of Ni3Al can be greatly improved [8]. At the same time, the wettability of Ni3Al on WC and TiC is sufficient and the possibility... mechanical properties comparable to that of commercially available WC-Co and TiC-Ni cermets, but the WC-Ni3Al composites form a semi-continuous second phase with some remnant Ni3Al-rich areas owing......

nm,对该析出物进行能谱分析,结果如图9(b)所示,该析出物析出物也富含Nb和Ti,可以确定为(Nb,Ti)C.分析认为,这种椭圆形的析出物是在奥氏体内形成TiC,而后NbC以其作为核心析出并长大.相关研究表明[9],在α-Fe中,析出物的位向与基体存在的相关性为(001)M(C,N)∥(001)α-Fe,[010]M(C,N)∥[110]α-Fe.在这种取向关系下,析出相晶格与α-Fe晶格在3个......
