by using optical microscope (OM) and field-emission scanning electron microscope (FESEM, Hitachi S-4800, Japan) with an energy dispersive spectrometer (EDS), and the average grain size was measured......
structure. In the present study, the borides mainly exhibit flaky morphology, which are non-equilibrium morphologies in the view of interfacial energy and strain. The pinning of α grain boundary by such particles will result in the formation of high-energy phase boundary, which contains a high density of defects such as dislocations and planar faults. According to the heterogeneous nucleation theory......
