研究了一种偏离<001>取向15o的镍基单晶高温合金的中温蠕变(760℃/793 MPa)性能和变形组织。结果表明:取向靠近<001>-<101>边界合金的蠕变寿命最长,而取向靠近<001>-<111>边界合金的蠕变寿命最短.虽然三种试样取向偏离<001>的夹角都约为15o,但是其微观变形组织明显不同.取向靠近<001>-<101>边界试样的变形主要受控于{111}<110>滑移系,而取向靠近<001>-<111>边界试样变形主要受控于{111}<112>滑移系. |

The intermediate temperature creep behavior and microstructure of samples misaligned 15o from <001> crystallographic axis for a nickel-based single crystal superalloy were systematically investigated. The results show that the creep life of samples with orientation close to the <001>-<101> symmetry boundary is the longest, while the creep life of samples with orientation close to the <001>-<111> symmetry boundary is the shortest. Although the misorientation angles of the three samples deviated from <001> were all about 15o, their microstructure was obviously different. The deformation of the samples close to the <001>-<101> was mainly controlled by the sliding system of {111}<110>, while the deformation of the samples close to the <001>-<111> was mainly controlled by the sliding system of {111}<112>. |
