Location and Orientation Specific Material Property Evaluation of Friction Stir Welded Ti‐5111: A Microsample Approach
2014
This work presents microsample measured mechanical properties of a friction stir welded (FSW) plate of Ti-5111. Property measurements and fractographic deformation observations were made as a function of discrete locations within the weld [stir zone (SZ), boundaries, base metal (BM)]. Properties in the longitudinal direction are compared to transverse measurements made at the same locations. Compared to the BM the longitudinal direction shows strength and ductility increases throughout the weld. The outer SZ showed mechanical properties in the longitudinal direction to be similar to the SZ properties in the transverse direction. These observations and measured properties serve to link the local material properties to the complex flow, heat, and deformation imparted to the material during the FSW process.
