  • In order to study the effect of hot rolling finishing temperature on the properties of deformation-aging state QBe2 alloy sheet, the mechanical and physical properties of QBe2 alloy sheets are measured, combined with scanning electron microscope (SEM) microstructure of different heat treatment state. The results show that the deformation-aging state QBe2 alloy sheet with a lower hot rolling finishing temperature (540 ℃) contains larger amount of β phase and presents a more severe phenomenon of grain boundary desolvation when the hot rolling finishing temperature ranges from 540 ℃ to 630 ℃. When the hot rolling finishing temperature increases from 540 ℃ to 630 ℃, the strength of deformation-aging state QBe2 alloy sheet increases approximately 80~90 MPa. The elongation increases by 1.2% and the Young’s modulus increases approximately 10 GPa while the conductivity decreases by 1.8%. Due to different contents of β phase in the microstructure, the properties of deformation-aging state QBe2 alloy sheets with various hot rolling finishing temperatures are different.
