| 摘 要： | 借助于试验及温度场模拟对TiAl合金精铸叶片表层晶体形态及其分布进行了研究,结果表明合金叶片表面晶体形态分布与凝固温度场分布有很大关系,随表面区域温度场的不同,表面晶体形态明显发生变化.同时发现表面晶粒度对浇注温度有较强的依赖性. |

| Abstract: | Surface grain structures and distributions of TiAI alloy precision blade castings were studied with experiments and temperature field simulation. Results indicated that when TiAI alloy melt was poured in to ceramic mold, surface grain structures were apparently changed duo to the different local surface temperature fields. Moreover, the surface grain size strongly depended on pouring temperature. |
| Keywords: | TiAl alloy surface microstructure simulated temperature distribution |
