Abstract: Disclosed herein are embodiments of an Al—Ce—Ni alloy for use in additive manufacturing. The disclosed alloy embodiments provide fabricated objects, such as bulk components, comprising a heterogeneous microstructure and having good mechanical properties even when exposed to conditions used during the additive manufacturing process. Methods for making and using alloy embodiments also are disclosed herein.

Abstract: An apparatus which is convertible between a multi-wheeled vehicle and a multi-legged stationary structure such as a table, crib or playpen. The invention is comprised of a main body to which are attached wheel assemblies capable of freely pivoting movement under the force of their own weight when the body is lifted. Wide tires are provided which, after swiveling downward, will result in supporting the body. The wheel thickness is enough so that the vehicle rolls well in soft or sandy soils, while contributing to the resulting height of the raised body, after the vehicle is lifted and the wheel assemblies have pivoted down into their vertical position.
