Abstract:

Discontinuous fibers of Mo were incorporated in matrices of nickel base superalloys INCO 625, INCO 713LC, IN-100, and TDNiCr by coextrusion of blended powders. An elevated temperature stress rupture test showed that fiber strengthening was obtained only in INCO 625 in the temperature region of 1500 to 1700F.
