The effect of sintering process and ZrO2 contents on formation of intragranular ZrO2 in Al2 O2 matrix was investigated with a-Al2O3 micro-powders and ZrO2 nano-
The anode material Zn4SO4 (OH)6 · 5H2O for nickle/zinc batteries was synthesized by hydrothermal method and was identified by XRD techniques. TG/DAT measur
The micro structure evolution mechanism in adiabatic shear band in commercial pure titanium (TA2) at high strain rates(γ≈105 - 106/s) were studied. The nanosi
Wrinkling and fracture are main defects in sheet metal forming of aluminum alloy sheet, which can be reduced or even eliminated by manipulating a suitable blank
