无机材料学报 doi:10.3724/SP.J.1077.2006.01167

利用中间相沥青纤维中沥青分子的高度择优取向和适度的热塑性热压制备高导热块体炭材料. 对比研究了经不同氧化处理的带形及圆形中间相沥青纤维热压所得炭材料的传导性及力学性能.
结果表明: 相对圆形纤维来说, 由于带形中间相纤维具有更高的纤维轴向取向度和纤维之间更高的接触面积, 故其热压所得材料具有...

In this paper by means of TEM and HREM, we found that the presence of r-phase plays the most important role in enabling two way shape memory effect (TWME) to be obtained by the stabilization of stress induced martensite variants (SSIM). This idea is different from the traditional suggestion that str...
