Engineered powder compact composite material

摘要

An engineered dispersed particle-cellular nanomatrix composite material is disclosed. The engineered dispersed particle-cellular nanomatrix composite material is configured for contact with a fluid and configured to provide a selectable and controllable transition from one of a first strength condition to a second strength condition that is lower than a functional strength threshold, or a first weight loss amount to a second weight loss amount that is greater than a weight loss limit, as a function of a time in contact with the fluid.

1. An engineered dispersed particle-cellular nanomatrix composite material comprising a substantially-continuous, cellular nanomatrix of a nanomatrix material, a plurality of dispersed particles comprising a particle core material dispersed within the nanomatrix and a solid-state bond layer extending throughout the cellular nanomatrix between the dispersed particles, the dispersed particle-cellular nanomatrix composite material comprising deformed powder particles formed by compacting powder particles comprising a particle core and at least one coating layer, the coating layers joined by solid-state bonding to form the substantially-continuous, cellular nanomatrix and leave the particle cores as the dispersed particles, the dispersed particle-cellular nanomatrix composite material configured for contact with a fluid and configured to provide a selectable and controllable transition from one of a first strength condition to a second strength condition that is lower than a functional strength threshold, or a first weight loss amount to a second weight loss amount that is greater than a weight loss limit, as a function of a time in contact with the fluid.
