A method of producing, from a continuous or discontinuous (e.g., chopped) carbon fiber, partially to fully converted metal carbide fibers. The method comprises reacting a carbon fiber material with at least one of a metal or metal oxide source material at a temperature greater than a melting temperature of the metal or metal oxide source material (e.g., where practical, at a temperature greater than the vaporization temperature of the metal or metal oxide source material). Additional methods, various forms of carbon fiber, metal carbide fibers, and articles including the metal carbide fibers are also disclosed.

A multi-component or composite inorganic fiber comprising a nano-scale contiguous collection of a plurality of packed unique phases of material randomly interspersed throughout the fiber body, without unwanted impurities, and a method for producing same. Said phases include three or more foundational chemical elements from the Periodic Table mixed together during fiber production, producing distinct material phases interspersed throughout the fiber volume.

A ceramic matrix composite includes continuous silicon carbide fibers in a ceramic matrix comprising silicon carbide and a MAX phase compound having a chemical composition M.sub.n+1AX.sub.n, where M is a transition metal selected from the group consisting of: Ti, V, Cr, Sc, Zr, Nb, Mo, Hf, and Ta; A is a group-A element selected from the group consisting of: Al, Si, P, S, Ga, Ge, As, Cd, In, Sn, Tl and Pb; and X is carbon or nitrogen, with n being an integer from 1 to 3.

Systems and methods for the manufacture of a solid wire using additive manufacturing techniques are disclosed. In one embodiment, a fine powdery material is sintered or melted or soldered or metallurgically bonded onto a metal strip substrate in a compacted solid form or a near-net shape (e.g., a near-net solid wire shape) before being turned into a final product through forming or drawing dies.

The present invention discloses a polymetallocarbosilane from organic metal catalysed polymerization and uses thereof, said polymetallocarbosilane has a structural formula as shown in (I).

##STR00001##

In the formula, R is methyl, ethyl, propyl, ethenyl, chloromethyl, phenyl or phenethyl; M is Ti, Zr or Hf; m is an integer equal to or greater than 1, n is an integer equal to or greater than 0, and Cp.sub.1 and Cp.sub.2 are each a cyclopentadienyl or substituted cyclopentadienyl group. The present invention adopts a method for producing polymetallocarbosilane by metallocene catalysed addition polymerization of an organosilane, with adjustability of metal content in polymer, simple reaction steps, mild reaction conditions and low preparation costs.

A ceramic matrix composite includes continuous silicon carbide fibers in a ceramic matrix comprising silicon carbide and a MAX phase compound having a chemical composition M.sub.n+1AX.sub.n, where M is a transition metal selected from the group consisting of: Ti, V, Cr, Sc, Zr, Nb, Mo, Hf, and Ta; A is a group-A element selected from the group consisting of: Al, Si, P, S, Ga, Ge, As, Cd, In, Sn, Tl and Pb; and X is carbon or nitrogen, with n being an integer from 1 to 3.
