A PROCESS FOR PRODUCING A METAL-MATRIX COMPOSITE OF SIGNIFICANT ?CTE BETWEEN THE HARD BASE-METAL AND THE SOFT MATRIX

摘要

THE PRESENT INVENTION RELATES TO A PROCESS FOR PRODUCING A METAL-MATRIX COMPOSITE OF SIGNIFICANT ?CTE BETWEEN THE HARD BASE-METAL AND THE SOFT MATRIX. THE PROCESS INCLUDES THE STEPS OF SINTERING, PRESSING AND ENFORCED INFILTRATION OF THE METAL-MATRIX COMPOSITE COMPACT ACTING WHEREIN THE PROCESS IS DRIVEN BY DIFFERENTIAL THERMAL EXPANSION COEFFICIENTS BETWEEN SHELL AND CORE MATERIALS. THE MOST ILLUSTRATIVE DRAWING:
