temperature is 200 °C, the annealing time has little effect on the plasticity of the material. In the case of non-annealing, the plasticity of the material is poor, at that time the elongation is 4.3%. After... decreased significantly and it dropped from 748 MPa at non-annealing to 463 MPa at this time. Compared with Figs. 6(a) and (b), it can be found that the addition of Zr reduces the plasticity......

Due to high excitation binding energy (60 meV) at room temperature, large direct band gap (3.37 eV), environmental stability, non-toxicity and low cost, ZnO... organic pollutants, leading to the formation of carbon dioxide and water which are non-toxic for the environment [10]. The photocatalytic utility of powdered nano- materials has two practical limitations......
, the recrystallization annealing process was conducted for tensile specimens of the AZ31 magnesium alloy. The specimens were heated to 350 °C at the heating rate of 5 °C/min and then cooled down to the room... in elastic deformation stage of specimens. In general, the atoms in the crystal lattice of the material are not in the stationary state, but in the micro-vibration state near the equilibrium position......
