All iliac hone graft fused well and a great deal of bony callus was found the vertebral body surface. Lucency area was in seen surrounding the hone graft, titanium and AC-AFF on the X-ray films, and there wan new bone formation in the interface of internal union and bone. The central region of titanium and AC-AFF became vague and new bone formation was found in the intracavitary aim of implants by CT scan. And port of the new hone transited the parietal reticulation and connected with normal ones at titanium and AC-AFF.

Using of optical microscopy, X-ray diffraction, transmission electron microscopy, hardness and tensile testing, the effect of thermal exposure at high temperatures on the microstructures and of high-temperature tensile properties of rapidly solidified AlCrYZr have been studied. The results show that there are two main phases,Al20Cr2Y(cubic, a=1.437 nm) and DO23Al3Zr(terganal, a=0.4 013 nm , c= 1.732 nm), in the as-solidified alloy. The Al20Cr2Y phase can maintain its cubic structure at 500℃, but the particles coarsen remarkably and even become lumpish. In coarse lumpish Al20Cr2Y phase the plane faults and twin structures exist.

摘 要：采用金相、 X射线衍射、透射电镜、硬度测定和拉伸试验研究了高温热暴露对快速凝固AlCrYZr合金显微组织影响和高温下力学性能的热稳定性，结果表明，快速凝固AlCrYZr合金主要第二相为Al20Cr2Y(立方，a=1.437nm)和DO23Al3Zr(正方，a=0.401 3nm， c=1.732nm)，Al20Cr2Y在500℃热暴露尚能保持其立方结构，但质点明显粗化，甚至块状化，在粗大的Al20Cr2Y相中存在有层错和孪晶结构。
