In order to comprehensively understand the forming mechanism of abnormal phases solidified in a nickel-base cast superalloy with additives of tungsten and molybdenum, the coupling effects of W and Mo on the microstructure and stress-rupture properties were investigated in this paper. The results indicated that the precipitation of primary α-（W, Mo） phase depended tremendously on the amount of W and Mo addition. When the total amount of W and Mo was greater than 5.79 at%, α-（W, Mo） phase became easily precipitated in the *** increasing of Mo/W ratio, the dendrite-like α-（W, Mo） phases were apt to convert into small bars or blockylike phases at the vicinities of γ′/γ eutectic. The morphological changes of α-（W, Mo） phase can be interpreted as the non-equilibrium solidification of W and Mo in the alloy. Since the large sized α-（W, Mo） phase has detrimental effects on stress-rupture properties in as-cast conditions, secondary cracks may mainly initiate at and then propagate along the interfaces of brittle phases and soft matrix. During exposing at 1100 ℃ for 1000 h, the α-（W, Mo） phases transformed gradually into bigger and harder M;C carbide, which results in decreasing of stress-rupture properties of the alloy. Finally, the alloy with an addition of 14W-1Mo（wt%） maintained the longest stress lives at high temperatures and therefore it revealed the best microstructure stability after 1100 ℃/1000 h thermal exposure.

Nanosecond (ns) photoelectric effects have been observed in all-oxide p-n junctions of La0.9Sr0.1MnO3/SrNb0.01Ti0.99O3 for the first time. The rise time was about 23 ns and the full width at half maximum was about 125 ns for the open-circuit photovoltaic pulse when the La0.9Sr0.1MnO3 thin film in the p-n junction was irradiated by a laser of ~20 ns pulse duration and 308 nm wavelength. The photovoltaic sensitivity was 80 mV/mJ for a 308 nm laser pulse.

对不同W含量的镍基高温合金的显微组织和1 100℃的抗拉强度进行了对比研究。结果表明,随着W含量的增加,合金次生γ′相形貌由规则的方块状聚集长大为不规则形状,体积分数由51.1%先增加至61.8%后下降至55.3%,在1 100℃的抗拉强度从405MPa先增至488MPa后降至433MPa。低W含量合金由于次生γ′相的体积分数较少而具有较低的高温抗拉强度,高W含量合金高温抗拉强度下降的主要原因是析出的α(W)相引起的次生γ′相的体积分数的下降。W含量为13.0%和15.5%的合金在1 100℃具有较高的抗拉强度,达440~488 MPa。
