Does anyone know the correlation between critical temperature and Ductile-Brittle Transition Temp. on the mechanical properties of bcc pillars?

I am working on single crystal bcc metal pillars diameters ranging from 300 nm to 5 microns. I am trying to clarify the effect of both Tc and DBTT on mechanical properties of bcc metals.
