5.1.1 Yield strength and mechanical resistance
If we talk about the hardening involved in TiAl alloys, we should be aware that the increased resistance to dislocation slippage can manifest itself in several ways:
solid solution hardening using additive elements (Nb, Cr, etc.);
hardening by refinement of the microstructure (Hall-Petch law);
hardening by strain-hardening (via thermomechanical...
