The results show that at high temperature of graphite furnace PTFE can convert chromium oxide into chromium fluoride to reduce the formation of refractory carbide.

结果表明，PTFE在高温下可以将铬的氧化物转化为氟化物，阻止难熔碳化物的形成。

By the OM and SEM observation of solidification microstructure, the interfacial reaction between TiAl alloy and Al2O3 crucible was serious, and a large number of α-Al2O3 inclusion formed in the solidification microstructure. The interfacial reaction between TiAl alloy and ZrO2 crucible occurred only on the sample surface, but the crucible was not stable at high temperature and a tack coating was formed, clinging tightly with TiAl alloy. C element in the graphite crucible changed the original solidification path of TiAl alloy, and club-shaped γ-TiAl phases formed.

通过用光学显微镜和扫描电镜对凝固组织观察发现，TiAl合金与氧化铝坩埚之间的界面反应较为严重，在凝固组织中形成了大量氧化铝夹杂；TiAl合金与氧化锆坩埚的界面反应仅发生在试样表面，但该坩埚在高温下不稳定，并在试棒表面形成一层无法剥离的粘结层；石墨坩埚中的C元素改变了原有TiAl合金的凝固路径，生成了棒状的γ-TiAl相。
