Generate a picture of a schematic diagram of the mechanism of grain boundaries, dislocations and nano-precipitations scattering phonons of different frequencies and enhancing mechanical properties
Generate a picture of a schematic diagram of the mechanism of grain boundaries, dislocations and nano-precipitations scattering phonons of different frequencies and enhancing mechanical properties. Phonon frequencies include low, medium and high frequencies. The mechanical strengthening mechanism includes grain boundary strengthening, dislocation hardening, and dislocation-precipitation interaction
