since you are using a Ti alloy design for strength,the TiN precipitates you see as we discussed are most likely related to precipitation formation during coil cooling.The fact that you have success at 21.1 mm and then charpy stability problems at 25.1 mm is most likely due to non-uniform grain size distribution across the thickness.In addition,since you are not using and Nb and only Ti there is very little “pancaking” going on as the Tnr for the Ti level you have is < 850 C.This means that most of the rolling is being done in the recrystallized region with maybe only the last 2 finish stands resulting in non-recrystallized (pancake) rolling going on where the temperature is < 850 C.
Make the roughing reduction on the last pass prior to the transfer bar thickness be the largest reduction.This will allow for good cross sectional austenite conditioning to occur giving you the finest most uniform cross sectional grain size as possible.

因为你是用钛合金设计强度、锡沉淀你看到像我们讨论过的最有可能在线圈形成沉淀相关的冷却.你已经成功的事实,然后在结构钢正在毫米毫米在25.1稳定性问题是最有可能因非均匀的粒度分布在各个层的厚度.此外,既然你不是唯一使用和铌、钛有极少的“pancaking Tnr“正在进行的钛的水平是< 850个c.这意味着大多数的
