| Description/Abstract | This work investigates precipitation hardening of the fully lamellar structure of an investment cast Ti-47Al-2Nb-1Mn-0.5Mo-0.5W-0.2Si alloy. The as cast columnar lamellar structure, as well as the bulk B2 phase and silicides, formed during solidification, complicate the analysis. As such, a full solution treatment in the {alpha} phase field was applied to the as cast material to produce an equiaxed fully lamellar structure without the bulk B2 phase and silicides. This lamellar structure was used as the starting microstructure to investigate precipitation hardening of the fully lamellar structure. When appropriately aged to contain dispersed silicides and/or {beta} particles this structure may have favorable creep properties. |
