College of Energy Engineering... of high temperature heat pipe with triangular grooved wick. The effects of the inclination angle and geometry structure were considered in the proposed model. Maximum heat transfer capacity was also......
) in titanium alloy TC11 at high temperature and the influence of oxygen solution layer on performances of substrate were characterized with the help of apparatus, such as TGA,SEM/EDAX, XRD, EPMA, Micro-hardness.... Titanium alloys with oxygen solution layer exhibited improved corrosion resistance both in 3.5 % NaCl and in 5 % HCl solution. Oxidation resistance of TC11 with oxygen solution layer at high temperature......
using an EBSD system mounted on LEO-1450 SEM. The results show that the substrates that are hot rolled have a sharp cube texture and low-angle grain boundaries. Key words:high temperature... were extensively used as substrates for coated conductor. The thermomechanical process usually includes hot forging and cold rolling. In this study, a hot-rolling process between hot forging and cold......
] and accumulative roll bonding (ARB)[7]. However, there has been a little attempt to improve the room temperature mechanical properties of Mg-based alloys through the use of simple high ratio extrusion (HRE.... Whatever the temperature, the recrystallization leads to the development of fine equiaxed and homogeneous grains. The mean grain sizes after high ratio extrusion at 250, 300 and 350 ℃ are 4, 5 and 8 mm......
