Heat Treatment

Through the comparative study of the microstructures of TC4 titanium alloy laser rapid forming parts under three states of deposition, stress relief annealing and solution aging, the ways to improve the microstructure of TC4 titanium alloy laser rapid forming and improve the comprehensive mechanical properties of materials were explored. The results show that the microstructure of the molded part is composed of thick columnar grains that grow epitaxially through multiple cladding layers, and the main axis of the columnar grains is perpendicular to the laser beam scanning direction or slightly inclined to the beam scanning direction. The microstructure of the original columnar β-Ti grains is composed of a very small amount of needle-like α, a large number of Widmanstatten α laths and a certain volume fraction of inter-lath β phase. After the annealing treatment of the as-deposited sample, the α lath tends to be coarsened, the performance improvement is not obvious, and the plasticity is improved; after the solution aging heat treatment, a triple mixed structure of equiaxed α, basket α and transformed β phase can be obtained. The α-phase at the grain boundary is broken to varying degrees, or even disappears, the plasticity is obviously improved, and the strength is not greatly reduced, and it has good comprehensive mechanical properties.

The effects of heat treatment on the microstructure, tensile properties, fracture toughness and fatigue crack growth rate of TC4-DT alloy quasi-300mm bars were studied. The results show that the microstructures of TC4-DT after simple annealing at 800℃×2hAC, solid solution + aging in α + β phase region, and solid solution + aging in β phase region are equiaxed, bimodal and flaky, respectively. organize. Equiaxed microstructure has better tensile properties, low fracture toughness and high fatigue crack growth rate; compared with equiaxed microstructure, bimodal microstructure has better tensile properties, higher fracture toughness and lower fatigue crack growth rate. Fatigue crack growth rate; the tensile strength of the lamellar structure is lower than that of the two-state structure and equiaxed structure, the plasticity is the lowest, and the fracture toughness and fatigue crack growth rate are basically the same as those of the two-state structure. In general, TC4-DT alloy can obtain Rm≥825MPa, RP0.2≥750MPa, A5≥8%, KIC≥90MPa after treatment of α+β phase zone solid solution + aging, β phase zone solid solution + aging treatment , The fatigue crack growth rate is less than the comprehensive performance of 8×10-6～9×10-6mm/cycle.
