alloys [32]. Linear-elastic fracture mechanics (LEFM) and non-linear fracture mechanics were employed to explain the fatigue cracking behaviors of cast Al alloys. LEFM assumes that material.... Non-linear fracture mechanics, on the other hand, is used for cases that materials are not perfectly elastic and undergo a certain extent of plastic deformation at the crack tip. Based on LEFM, Al......
. Heating rate and cooling rate were 5 ℃/min. 2.3 Thermodynamic calculation and characterization The Gibbs free energy changes of the designed reactions at corresponding temperature were calculated, which......
. Plated samples were annealed at temperatures from 373 K to 498 K for 0.5-5.0 h. The annealing process was done in a forming gas (95% N2+5% H2, volume fraction) atmosphere at a heating rate of 100 K... that only Cu6Sn5 forms. The Cu6Sn5 layer is still non-uniform with protrusions at some locations. A particularly prominent protrusion extending into the Sn matrix, perhaps along Sn grain boundary, is shown......

The climate of the South China Sea has been affected mainly by the western Pacific warm pool since the late Quaternary, and the climate change curve was jagged and showed characteristics of slow heating......
manual shaking. Digestion was continued by heating the tube to 85 °C in a water bath for 2 h. The watch glass was removed and the tube content was evaporated to a small volume (1±0.5) mL. A second 5...). The residual or non- extractable metals are retained within the crystal lattices of minerals and inside crystallized oxides. And this kind of metals would steadily exist in the residue for a long time [33,34......
