Abstract

The invention relates to a double-chamber high-temperature forging and forming device of a TiAl intermetallic compound forge piece and a method thereof, belonging to forming methods and devices of TiAl intermetallic compound forge pieces. The invention solves the problems of large heat loss, large deformation resistance, small forging deformation, difficult forging and the like generated when thetraditional forging technology is used for forging the TiAl intermetallic compound forge piece. A blank heating chamber and a mould heating chamber are adjacently arranged and a movable baffle plate is arranged between the blank heating chamber and the mould heating chamber, and a hearth of the blank heating chamber and a hearth of the mould heating chamber are mutually penetrated and mutually independent by pulling the movable baffle plate up and down. TiAl blanks and a mould are heated to 1230-1300 DEG C and 800-1000 DEG C respectively in different heating chambers; the movable baffle plateis opened to push the TiAl blanks into the mould heating chamber along a carrying platform and put the TiAl blands into a mould cavity; and the mould is closed for forging. The invention is used for high-temperature forging and forming of TiAl intermetallic compound materials.

Description

technical field [0001] The invention relates to a forming method and device for a TiAl intermetallic compound forging, belonging to the technical field of forging forming technology. Background technique [0002] With the rapid development of industries such as aerospace and automobile manufacturing, the industry has put forward higher and higher requirements for the performance of lightweight heat-resistant structural materials. In this context, TiAl intermetallic compound materials with low density, high specific strength, high specific modulus, and excellent high-temperature mechanical properties and oxidation resistance have become the focus of material research in the past decade, and may be used in some Within a certain range of the field, it has successfully replaced some traditional high-temperature structural materials - titanium-based alloys and nickel-based alloys. [0003] However, TiAl intermetallic compounds have L1 0 Type-ordered crystal structure, low cryst...
