TiAl基合金的显微组织的研究

STUDIES OF THE MICROSTRUCTURE OF TiAl-BASED ALLOYS

本文使用热水淬火方法,研究了冷却介质冷却能力对TiAl基合金相变时组织形态的影响,试验发现,TiAl基合金能够发生非平衡组织转变,转变后的组织形态受冷却能力的影响,可以呈现复杂现象。

Studies showed that the cooling capacity of quenching agents is one of factors affecting the microstructurcs of TiAl—based alloys after their phase transformations during hot water quenching. It has been round that TiAl-based alloys can undergo a nonequilibrium microstructure transition which leads to complex microstructures depending on the capacities of quenching agents used.
