Abstract: DISPERSOID STRENGTHENED COPPER METALS CHARACTERIZED BY A COPPER MATRIX AND A REFRACTORY DISPERSOID ARE PRODUCED BY ROLL COMPACTING PARTICLES CHARACTERIZED BY CERTAIN SPATIAL AND METALLURGICAL RELATIONSHIPS. THE SPATIAL CONSIDERATIONS ARE CHARACTERIZED BY PRACTICABLE RELATIONSHIPS IN COPPER PARTICLES BETWEEN SURFACE AREA AND OVERALL DIMENSIONS. THE METALLURGICAL RELATIONSHIPS ARE CHARACTERIZED BY CRITICAL LIMITS OF DIMENSIONS AND SPACING OF DISPERSOID SUBPARTICLES OR COMPONENTS THEREOF ON OR IN THE COPPER MATRIX PARTICLES EITHER BEFORE OR AFTER ROLL COMPACTING.

Abstract: IN THE PRODUCTION OF DISPERSOLD STRENGTH COPPER BY FUSION METALLURGY, FOR A PARTICULAR COPPER MATRIX-DISPERSOID PARTICLE SYSTEM CHARACTERIZED BY PARTICULAR SPATIAL AND WETTING RELATIONSHIP, REQUIREMENTS FOR STABLE AND UNIFORM EQUILIBRIUM ARE INDICATED WHEN THE SYSTEM IS MOLTEN AND WHEN THE SYSTEM IS SOLIDIFYING AND SOLIDIFIED. IN THE MOLTEN SYSTEM, FOR THE GIVEN WETTING RELATIONSHIPS, ESTABLISHMENT OF SUCH EQUILIBRIUM HAS BEEN FOUND TO BE A FUNCTION OF SPATIAL RELATIONSHIPS AMONE SIZE, SEPARATION AND VOLUME CONCENTRATION OF THE PARTICLES. IN THE SOLIDIFYING AND SOLIDIFIED SYSTEM, FOR THE GIVEN SPATIAL RELATIONSHIPS, MAINTENANCE OF SUCH EQUILIBRIUM HAS BEEN FOUND TO BE A FUNCTION OF SYSTEM COMPOSITON AS DETERMINATIVE OF THE WETTING RELATIONSHIPS.
