Abstract Scope Time to market for new materials in the aerospace industry is typically measured in decades, due to the need to quantify material behaviour and ensure safe usage. Predictive material models contain details of the material’s microstructure and micro-scale mechanical response, they not only reduce this time significantly but inform the design of new materials. Titanium alloys are used in many critical jet engine applications, significant gains in jet engine performance could be realized if software tools were capable of better predicting deformation behaviour. Room-temperature deformation will be examined with the aim of developing software tools capable of predicting deformation and failure. A parameter study, varying single crystal material parameters in crystal-scale finite element simulations will be presented, with emphasis on strain rate sensitivity. Comparisons will be made between simulations and physical experiments using in-situ micro-mechanical testing and high-energy x-ray diffraction. Differences will be investigated enabling refinement of predictive capabilities.
