Conclusion

Most nonmetallic inclusions are brittley ruptured in very rapid deformation, or brittle laminations form on their interface with the matrix. Ductile sulfides are nonuniformly deformed. In the matrix deformation is localized around the inclusions. Besides, zones adjacent to inclusions are characterized by the development of deformation by the rotational mechanism.

Explosive loading causes phase transformations in the inclusions of the type of spinoidal disintegration, and it also causes the transition of some kinds of inclusions into the metastable state.
