Abstract
A method of making a multi-composition fiber is provided, which includes providing a precursor laden environment, and forming a fiber in the precursor laden environment using laser heating. The precursor laden environment includes a primary precursor material and an elemental precursor material. The formed fiber includes a primary fiber material and an elemental additive material, where the elemental additive material has too large an atom size to fit within a single crystalline domain within a crystalline structure of the fiber, and is deposited on grain boundaries between adjacent crystalline domains of the primary fiber material to present an energy barrier to atomic diffusion through the grain boundaries, and to increase creep resistance by slowing down growth between the adjacent crystalline domains of the primary fiber material.
