Abstract
Successful reinforcement of two powder metal matrix systems with improvement of room and elevated temperature properties through incorporation of metal fibers or fiber glass is reported. Fiber parameters such as length, diameter, volume fraction and placement, as well as methods of processing, are discussed.
Fiber-reinforced nickel, cobalt, and their alloys are shown to have improved tensile properties, particularly at 2000°F. Hot-pressed composites produced tensile strength values up to two times greater at room temperature and up to 17 times greater than the unreinforced matrix at 2000°F. Rolling of these materials into three-inch-wide strips produced lower strength than in as-pressed condition.
Tensile, stress rupture, and bend test results are presented for aluminum nuclear fuel core sections reinforced with fiber glass. It is shown that improved tensile strengths and impact strength are experienced on both hot-pressed and rolled structures. Results on irradiated tensile specimens indicate radiation stability of product.
Based on work described, specific problem areas and remedial work in progress are discussed. Some projections on systems currently under investigation are offered.
