To improve the oxidation-resistance properties,SiC and TaC species were introduced in C/C composites by chemical vapor infiltration(CVI) methods. The oxidation-
微观结构和扔镁合金 Mg-6Al-0.5Mn (AM60 ) 的机械性质上的 silicocalcium 的效果被学习。结果证明扔镁合金的 AM60 的微观结构被增加 silicocalcium 的小数量有效地精制。Th
B 免费的 Ni_3Al (Zr ) 合金的张力的性质上的再结晶和环境(真空对空气) 的效果被调查。结果显示那茶碱完全重新使结晶,减轻压力的标本显示出最理想的韧性和最终的张力的力量,
The thin films of pure Cu and Cu-2.18%Cr(mole fraction,%) were deposited on Si(100) substrates. Then the samples were vacuum-annealed at 573-773 K to investigat
