中文摘要:
      以GH3536高温合金粉末为原料,通过添加稳定剂制得稳定的浆料,采用定向冷冻成型制备了定向多孔高温合金。结果表明:添加0.4~1wt.%的瓜尔豆胶或者1~3wt.%的羧甲基纤维素钠作为稳定剂可制备稳定的浆料;随着浆料固相含量从10vol.%增加到30vol.%,定向孔径从308μm减少到198μm,壁厚从 81μm增加到223μm,其轴向压缩强度从10.72MPa增加到75.02MPa,径向压缩强度从9.2MPa增加到78.49MPa;采用固相含量10~30vol.%的浆料制备的定向多孔高温合金是一种塑性材料,固相含量越高其吸能能力越好。

英文摘要:
      Oriented porous superalloy was prepared by freeze-casting with GH3536 powder as raw material and guar gum/CMC-Na as stabilizers. The results show that slurries could be stabilized by adding 0.4~1wt.% of guar gum or 1~3wt.% of sodium carboxymethylcellulose; as the solid loading increases from 10vol.% to 30vol.%, the width of oriented pore decreases from 308μm to 198μm and the wall thickness increases from 81μm to 223μm, with the axial and radial compressive strength improving from 10.72MPa and 9.2MPa to 75.02MPa and 78.49MPa, respectively. The fabricated oriented porous superalloy is a plastic material with the ability of absorbing energy.
