摘要

The microstructure characteristic of laser forming repaired(LFR) Ti-6Al-4V alloy was analyzed. The influence of annealing treatment on the microstructure of repaired region and the properties of repaired component were also investigated. The repaired component experienced a continuous microstructural transition from duplex microstructure with equixed α and lamellar α+β in the substrate zone(SZ) to the epitaxial coarser columnar β with Widmanstätten α+β through heat-affected zone(HAZ).The static load tensile properties of the repaired component were satisfied with the forging standard. After annealing treatment, α laths in the laser f orming repaired zone(LFRZ) have a tendency to coarsen and the comprehensive mechanical properties have been improved. The low cycle fatigue properties of the repaired components can be equivalent to that of the forging through annealing and shot-peening treatment.
