研究2种不同工艺制备的Ti60高温钛合金d300 mm棒材的显微组织及力学性能。结果表明：Ti60合金大棒材的显微组织靠近外表面的区域变形比较充分，显微组织均匀性较好，靠近心部区域a相的等轴化程度低，显微组织均匀性相对表面区域较差，这种差别会遗传到两相区的热处理态显微组织中；不同变形程度的大棒材显微组织尤其是a相的形貌略有差异，但除600 ℃轴向拉伸性能外，室温拉伸、蠕变性能差别很小，这主要是由于初生a相体积分数较低的缘故。
The microstructures and mechanical properties of d300 mm large-section Ti60 high-temperature titanium bars prepared by two different forging processes were investigated. The results show that the near-surface region exhibits more sufficient deformation than the interior region. Accordingly, a more homogeneous microstructure is found at the near-surface region. While at the interior region, more strip-shaped a phases are found. This phenomenon will be passed down to the corresponding the heat-treated microstructure. Though large difference especially a phase morphology is found in the two different deformed Ti60 large-section bars, the difference of tensile and creep properties between them is not so apparent, except the tensile properties at 600 ℃. This can be attributed to the less a phase volume fraction.
