Heterogeneous nucleation of martensite near free surface

A theoretical model is proposed which describes heterogeneous nucleation of an embryo of hcp-martensite near a free surface at a tilt grain boundary segment containing some extrinsic dislocations. The total energy gain due to the hcp-embryo nucleation is analysed in detail depending on internal (the...
