Which consequence results when exceeding the yield point of austenite?

💡 Explanation

Exceeding austenite's yield point causes plastic deformation, leading to increased imperfections like dislocations. These imperfections readily promote martensitic transformation because they act as nucleation sites, therefore forming more martensite, rather than maintaining equilibrium.
