Ductile high strength metallic filaments can be employed as reinforcement for brittle matrices such as fine ceramics. The glass-coated melt spinning of Cr and Co-base alloys was investigated as a means of producing a high strength and high toughness filament. The toughness was estimated from the area of stress-strain curves of the filament obtained. A continuous Cr–Ni–Fe–Si–B filament with a high toughness of 7000 MPa·% was obtained from the molten state at 1600 K for a winding speed up to 7.95 m/s.<BR>Ductile high strength filaments of Co–Mn–Si–B alloys were also successfully produced. A Co₆₈Mn₁₀Cu₂Si₅B₁₅ filament had the highest toughness of 10050 MPa·% with tensile strength of 4740 MPa and elongation of 4.0%. The filament consisted of micrograins with a grain size of 40×10⁻¹⁰ m.
