Abstract

Abstract

Properties and microstructure tests were carried out in Ti-6Al-4V extrusion under different transections to investigate the strength, damage tolerance and fatigue behaviors of different thickness of extrusion, as well as the contrastive analysis on microstructure of Ti-6Al-4V extrusion. The results indicate that tensile strength is lower while the thickness is higher, the fracture toughness is higher while the thickness is higher, the ‘T’ extrusion with higher thickness has higher fatigue and fracture toughness properties. In thicker cross-section of Ti-6Al-4V extrusion, there are clear grain boundary structures, and the mechanical properties are lower while fatigue and fracture toughness performances are higher, therefore, Ti-6Al-4V extrusion parts could be designed referring to the relationship between material properties and cross-section thickness in engineering.
