摘要
综述了TiAl基合金中几种常见的组织演变,着重论述了变形TiAl基合金在热处理过程中的晶粒长大及动力学、TiAl基合金在冷却时层状组织的形成和全层状TiAl基合金在高温时的非连续粗化这3种组织演变。
Several common kinds of microstructure evolutions in TiAl-based alloys are reviewed. Grain growth and its kinetics in deformed TiM-based alloys during heat treatments, formation mechanism of lamellar microstructures in TiM-based alloys and discontinuous coarsening in fully lamellar TiM-based alloys are described.
