Software was developed to model texture development during the high temperature forging of Ti-6Al-4V with an equiaxed-alpha microstructure. The software makes use of the Los Alamos Polycrystalline Plasticity (LApp) code in conjunction with the finite-element-modeling routine DEFORMä. The software indirectly couples DEFORMä with LApp and quantifies texture evolution at specific points in complex forgings whose metal flow has been characterized with DEFORMä. The methodology also takes into account partitioning of the imposed strain between the alpha and beta phases, models texture evolution for the alpha and beta phases separately, and allows for variant selection rules to be applied to describe the formation of secondary-alpha texture.
Summary: Software was developed to model texture development during the high temperature forging of Ti-6Al-4V with an equiaxed-alpha microstructure.
