Abstract: A thin-walled metal part, and a method to fabricate such a part out of various alloys. A plurality of layers are formed, each of the layers being formed on a polymer template or on a previously formed layer. A homogenizing heat treatment is used to cause chemical elements in the layers to interdiffuse, to form a single continuous layer with a substantially uniform alloy composition.

Abstract: An orthodontic appliance includes a portion made of a shape memory alloy having a base alloy composition of at least two different metallic elements and a treated region having an alloy composition that is depleted in at least one of the metallic elements. The base alloy may include a nickel titanium alloy (NiTi), a copper chromium nickel titanium alloy (CuCrNiTi), or a copper aluminum nickel (CuAlNi) alloy. The treated region may be depleted in at least one of copper, aluminum, nickel, and titanium relative to the base alloy composition by exposing the base alloy to a source of energy. The base alloy composition has a first austenitic finish temperature and the treated region has an austenitic finish temperature that may be different than the first austenitic finish temperature. The treated region may form a part of an archwire, a stop, a hook, a crown, a band, or an orthodontic bracket.

Abstract: A method for preparing a high entropy alloy (HEA) structure includes the steps of: preparing an alloy by arc melting raw materials comprising five or more elements; drop casting the melted alloy into a cooled mold to form a bulk alloy; applying an external force against the bulk alloy to reshape the bulk alloy; and heat-treating the reshaped bulk alloy, wherein the bulk alloy is reshaped and/or heat-treated for manipulating the distribution of the microstructure therein. The present invention also relates to a high entropy alloy structure prepared by the method.
