The effect of c/a ratio on the deformation of hcp metals?

It is confirmed that Al alloying increases the c/a ratio of Ti(Al) alloys, which in one aspect assists basal slip. Is there any physical mechanism or recommended paper on the impact of c/a ratio...

Does slip of Ti-Al alloys only depend on the shear deformation of solute atoms?

The effect of Al alloying on the deformation behavior of hcp Ti is summarized. It is found that the hardening rate (i.e., the slope of CRSS vs. Al concentration curve) of prismatic slip is higher...

Is the strength of coarse-grained hcp-Ti3Al is higher than that of fine-grained counterpart at the higher temperature?

Reviewer's comments: I have just one comment or question regarding the high strength being attributed to the coarse grain size of the Ti3Al. One would expect larger cracks to be produced in larger...
