Abstract:
      Effect of solution and aging heat treatment with lower temperature on the microstructures and mechanical properties of TC4 alloy bars were studied in this paper. Different heat treatment schedules were adopted and compared on titanium bars with fully equiaxed microstructure. The results show that with 700℃ solution temperature, strength of TC4 alloy decreases. Compared with the as forged alloy, rupture strength of the alloy reduce 77 MPa after solution treatment at 700℃. Aging at temperatures lower than 650℃ has great influence on the mechanical of TC4 alloy, aging at 400℃ could get ideal match of strength and plasticity.
