一种TiAl基合金轧制板材的制备方法
摘要：
一种TiAl基合金轧制板材的制备方法，以粉末冶金或铸锭冶金制TiAl基合金为坯料，采用低应变速率隔氧包套热轧制的方法制备出TiAl基合金板材。本发明对TiAl基合金的粉末冶金坯料、铸锭冶金坯料、锻造坯料均适用，应用范围广；工艺简单，设备简易，可推广性强；制备出的TiAl基合金板材变形程度高、表面质量完好、无开裂现象、变形组织均匀，且轧制工艺流程稳定，适用于工业化生产。
摘要（英）：

The invention relates to a preparation method of a TiAl-based alloy rolled sheet; and a TiAl-based alloy made from powder metallurgy or billet metallurgy serves as a billet, and the TiAl-based alloy rolled sheet is prepared through a low-strain rate oxygen barrier sheath hot rolling method. The preparation method of the TiAl-based alloy rolled sheet is applicable to powder metallurgy billets, ingot metallurgy billets and forged billets of the TiAl-based alloy, and has the advantages of wide scope of application, simple process, simple equipment and strong popularization; and the prepared TiAl-based alloy rolled sheet has the advantages of high deformation degree, good surface quality, no crack, uniform deformation tissues and stable rolling process, and is applicable to industrial production.
