中文摘要:
      采用X射线衍射(XRD)研究了不同退火温度下铪棒宏观织构的演变,采用场发射扫描电子显微镜(SEM)、X射线能谱分析(EDS)、X射线光电子能谱分析(XPS)研究了铪棒在360℃/18.6MPa进行28天水腐蚀后腐蚀产物的形貌、成分以及对腐蚀产物价态及迁移进行了表征。结果表明:热轧态的铪棒在RD-TD投影面出现了四种织构,表现为轴向复合织构。基面﹛0002﹜织构在各个阶段表现出很强的遗传性,其余织构均发生了不同变化。铪棒的腐蚀层由10~100nm的铪的氧化物颗粒堆积形成,柱面﹛10-10﹜退火织构比基面﹛0002﹜织构腐蚀速度快。腐蚀层优先形成Hf(4-x)+中间态氧化物,在生长过程中Hf(4-x)+失去电子变成Hf4+,与氧结合形成HfO2。

英文摘要:
      Abstract: The evolution of macro-texture of hafnium bars at different annealing temperatures was investigated by X-ray diffraction (XRD).The morphology and composition of corrosion products of hafnium bars at 360℃/18.6Mpa water was investigated by scanning electron microscope (SEM) and X-ray energy spectrum analysis (EDS) and X-ray photoelectron spectroscopy (XPS). The results shows that four types of textures appear on the RD-TD plane of the hot-rolled hafnium bars,appear as axial complex textures. The texture of the basal﹛0002﹜shows a strong heredity in each stage, and the rest of the textures has changed differently. The corroded layer of the hafnium bars is formed by stacking oxide particles from 10 to 100 nanometers, the corrosion rate of prismatic {10-10} annealed texture is faster than basel{0002}annealed texture. The corroded layer preferentially forms Hf(4-x)+ oxide, Hf(4-x)+ loses electrons and becomes Hf4+,forming HfO2 with oxygen during the growth .
