J. Cent. South Univ. (2012) 19: 2073-2080 DOI: 10.1007/s11771-012-1247-3 Hot-compression behavior of Al alloy 5182 TANG Jian-guo(唐建国), HUANG Xing-xing(黄星星), ZHANG Xin-ming(张新明) School of Materials.... According to the results of ENGLER et al [1], a high recrystallization rate has been observed in Al-Mg alloy due to addition of element Mg. However, recrystallization during self-annealing......
Microstructure evolution of TA15 titanium alloy during hot power spinningCHEN Yong, XU Wen-chen, SHAN De-bin, GUO Bin(School of Materials Science and Engineering, Harbin Institute of Technology, Harbin 150001, China)Abstract:The microstructure evolution of TA15 titanium alloy during hot power spinning was studied. Effects of wall reduction on microstructure evolution of TA15 titanium alloy were......
precipitates forms on Ni-10Al, while Ni-5Cr-10Al develops a protective layer. So the addition of Cr promotes the formation of alumina scale. The possible mechanism of Cr on the oxidation of Ni-Al alloy is discussed. Key words: Ni-Cr-Al alloy; Ni-10Al alloy; oxidation; third-element effect 1 Introduction Binary and ternary Ni-based alloys are often used as model systems to study the processes occurring......

alloys[18-20]. The Ti2Ni intermetallic compound has good combination of ductility because of its face-center-cubic crystal structure[14]. ISHIDA et al[21] indicated that TiNi alloy containing spherical... by the laser melting deposition. Abrasive wear resistance of the Ti2Ni/TiNi alloy was evaluated, and the corresponding mechanism was discussed. 2 Experimental Commercial pure Ti-Ni elemental powder blends......
