In Titanium, crack growth rates in MTRs are estimated to be 10x-100x that of the bulk material.This phenomenon has contributed to a number of turbine engine incidents over the past 40 years yet a great deal of uncertainty remains. Thus, a more detailed assessment of the impact of material texture and microtexture on material performance is required.In a broader context, it is anticipated that the methods developed herein could potentially find future use in quantifying local crack growth properties not only in MTRs, but other constituent particles of interest in multi-scale material model development.
