in heat resistant Mg-Y-Zn solid solution alloys [J]. Scripta Materialia, 2003, 48: 997-1002. [26] SELLARS C M, MCTEGART W J. On the mechanism of hot deformation [J]. Acta Metallurgica, 1966, 14......
and the crystal size of the samples were identified by X-ray diffraction (XRD, Rigaku, Cu Kα, λ=0.15418 nm). The changes both weight and heat along with the increasing temperature were studied......
are valves timing, engine load and speed. Other quantities and phenomena (such as gas inertial effect, and engine wall heat transfer) are just intermediate causes and affected themselves by the mentioned......
in Fig. 2, is established according to the method proposed by WANG et al [13]. The contact pairs are defined between the ring and rollers. The friction and contact heat conduction exist at the interface......

the microstructure of the powders. The desorption performance of the milled powders was measured by a simultaneous TG-DTA/DSC apparatus (STA449C), which was programmed to heat the specimens at rates of 5, 10......
were selected as the testing materials. To investigate both the geometry size effect and grain size effect, the materials were annealed at different annealing temperatures and holding time. The heat treatments were conducted in vacuum with a vacuum degree of 1.5 × 10-3 Pa to avoid the sheet foils from oxidation. After being etched, the average grain size of the heat-treated sheet foils......
compositions of Ce/Cr coatings are shown in Table 2. Then, the sealed can was placed in the rapid heat electric chamber furnace (GWL-1600) at 980 °C for 10 h, followed by air cooling to room temperature......
