was prepared by melting together commercial pure Al (CPAl) and Al-50wt.%Si master alloy in the appropriate ratio. The melt was prepared in a clay graphite crucible heated in a resistance furnace at 800......
, domains: 1290-1348 K, 0.2-0.5 s-1 and 1305-1370 K, 0.035-0.2 s-1; at ε=0.7, domains: 1290-1355 K, 0.042-0.26 s-1; at ε=0.9, domains: 1298-1348 K, 0.037-0.224 s-1. Key words: nickel-based superalloy; deformation activation energy; processing map; dynamic recrystallization 1 Introduction As a typical nickel-based alloy, Ni80A superalloy has been widely applied in the hot end components of a prime......
preparation and reagents The pure samples of spodumene were hand-picked from Koktokay Rare Metallic Mine, Xinjiang, China, and crushed to be less than 3 mm. A high intensity dry magnetic separator was used......
and T30, while using pure gasoline as a reference fuel (G100). Table 2 shows the properties of test fuels. 2.2 Engine setup and test conditions In this study, a single cylinder from a 2000 Ford......
Experimental 2.1 Materials and procedures The experimental alloy ingot was prepared through melting and casting. The raw materials included pure metals of Al, Cu, Li, Mg, Ag and Ni, and intermediate......

material suspensions is considered to be nonlinear scattering caused by microbubbles). SUN et al [52, 53] also studied the SSPM effect caused by thermal effects in pure solvents and solids. ABEYWICKREMA......
impacts bring about collapse by progressive folding, which has been found to absorb higher energy. Nevertheless, the pure axial impact condition is rarely observed in collision events, so the oblique......
of 90 wt.% Ti, 6 wt.% Al and 4 wt.% V as for Ti6Al4V. The minimum amount of Al needed to precipitate the intermetallic Ti3Al as a pure compound and as a mixture of (α+α2) is shown in Fig. 3(e......
, vehicle collision occurs under axial or oblique loadings. It is emphasized that a vehicle crash barely takes place under pure axial impact, and often occurs under oblique loading. Therefore......
