FIBER-REINFORCED METALS AND ALLOYS.

Abstract

The object of the program is to develop high strength-to-weight ratio metals and alloys through utilization of new or established fiber metallurgy techniques. The experimental approach was threefold involving (1) development of high strength, lightweight matrix materials; (2) production of high strength, high elastic modulus fiber particles; and (3) a fundamental study of the behavior of certain variable-strength fibers in a dissimilar matrix. Investigation of an Al10% mg demonstrated that the atomized powder could not be consolidated by hot extrusion; neither could powder made from a Al-10Mg-0.1TiB2 melt. Work under category (2) was confined to attempts to calibrate equipment and make fibrous crystals of wc by growth in a liquid phase. Some acceptable crystals were made, and the results were encouraging. For the third phase of the program the composite matrix selected was Ag and the fibers were cut from 0.003 in. diameter, 0.80% C wire. The initial variables in the study will be fiber content and heat treatment. (Author)
