Conclusions
The strength of a composite iron-base powder reinforced with disperse inclusions is 3–6 times that of the refractory compound itself. The highest strength is exhibited by composites containing 40–70 vol. % of refractory compound inclusions. When the particle size of a powder with such a composite structure is decreased, its grain strength grows as a result of work hardening of its matrix. A considerable increase in strength is due to the formation of interatomic bonds at phase boundaries.
