Abstract
The compression fracture behavior and mechanical properties of Ti80Al alloy and Ti48Al alloy solidified under 5. 5 GPa pressure condition were studied. The results show that the fracture of Ti80Al alloy solidified under high pressure has the characters of cleavage fracture and intergranular crack differing with cleavage fracture of that under vacuum. The fracture of Ti48Al alloy solidified under high pressure is cleavage fracture like that under vacuum. The compression strength of vacuum condition solidified Ti80Al alloy is 316 MPa. However when the solidification pressure is increased to 5. 5 GPa, the compression strength of Ti80Al is increased to 440 MPa. In the mean time, during ultra high pressure solidification the hardness of TI80A1 alloy and TI48A1 alloy increase from 8. 755 GPa and 5. 408 GPa under vacuum to 9. 572 GPa and 6. 227 GPa respectively, and elastic modulus also increase from 279. 3 GPa and 232. 3 GPa under vacuum to 295. 8 GPa to 252. 9 GPa respectively.
