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。

For naturally cooled monobloc barrel, its thermal condition in regular regime can be evaluated by measuring the outside temperature of two arbitrary rounds;(2) During a sustained firing process, unsteady heat conduction exists in a monobloc barrel, whereas unsteady and quasi steady heat conduction exist with actively cooled composite barrels, meaning that the thermal condition changes from uncontrolled to controlled;(3) Different combinations of the convective heat transfer coefficient h and thickness of gun barrel δ have much effects on cooling the bore temperature.

利用有限元软件分析了某大口径火炮身管的温度场分布，并对自然散热条件下的单筒身管和主动冷却条件下的复合身管温度场进行了比较，其结果为(1)身管温度场分布存在初始和正规工况阶段，后者的单筒身管热状态可以通过测定任意两发身管外表面温度来评估；(2)持续射击过程中，单筒身管始终处于非稳态导热过程，主动冷却身管则包括非稳态和准稳态两个过程，实现了身管热状态由不可控向可控转变；(3)对流传热系数h和身管壁厚δ的组合对降低内膛温度具有很大影响。
