The composition of TB6 alloy ingots after heat treatment then water colling and air colling was analyzed. The results show that the segregation in the grain boundary is more serious than the segregation in the grain both in air cooled ingot and quenching ingot, the composition in grain boundary are not uniform; the segregation of Fe is more serious than the segregation of Al and V; the composition in air cooled ingot and quenching ingot are more uniform than the composition in cast; the segregation in quenching ingot is lowest, quenching can reduce the segregation.

中文摘要：对热处理之后进行水冷与空冷的TB6合金铸锭进行了成分分析，对两种热处理所得结果进行分析，发现无论铸态还是空冷与水冷之后的试样，晶界偏析总比晶内严重，而且晶界处的成分分布很不均匀；Fe元素的偏析要比Al元素与V元素的偏析严重；空冷与水冷后的试样，各个元素分布较原始态的更加均匀，各测试点之间的差距减小；水冷之后的试样成分分布更理想，比空冷的效果好，水冷可以显著改善TB6合金铸锭偏析现象。
