A method of forming a component can include electrochemically depositing a metallic material onto a carrier component to a thickness of greater than 50 microns. The metallic material can include crystal grains and at least 90% of the crystal grains can include nanotwin boundaries. The metallic material can include a Copper-Silver alloy (Cu—Ag) with between about 0.5-2 at %-Ag.

Copper alloy film with high strength and high conductivity

A component for an electronic device can include a metal injection molded (MIM) metallic body that at least partially defines an exterior surface. The metallic body can have an average porosity less than 1% in a first region that extends from the external surface to a depth of at least 100 microns below the external surface, and an average porosity greater than 1% in a second region adjacent to the first region.

Surface treatment for metallic components

A method of forming a component can include electrochemically depositing a metallic material onto a carrier component to a thickness of greater than 50 microns. The metallic material can include crystal grains and at least 90% of the crystal grains can include nanotwin boundaries. The metallic material can include at least one of copper or silver.

Nanotwin copper components

Provided herein are titanium alloys that can achieve a combination of high strength and high toughness or elongation, and a method to produce the alloys. By tolerating iron, oxygen, and other incidental elements and impurities, the alloys enable the use of lower quality scrap as raw materials. The alloys are castable and can form &#x3b1;-phase laths in a basketweave morphology by a commercially feasible heat treatment that does not require hot-working or rapid cooling rates. The alloys comprise, by weight, about 3.0% to about 6.0% aluminum, 0% to about 1.5% tin, about 2.0% to about 4.0% vanadium, about 0.5% to about 4.5% molybdenum, about 1.0% to about 2.5% chromium, about 0.20% to about 0.55% iron, 0% to about 0.35% oxygen, 0% to about 0.007% boron, and 0% to about 0.60% other incidental elements and impurities, the balance of weight percent comprising titanium. There exists an unmet need to produce titanium alloys for use in aerospace applications which have a refined equiaxed grain structure. This can be beneficial for fatigue critical applications. The technology developed by QuesTek describes a titanium alloy and manufacturing methods thereof to obtain equiaxed grains on the order of 300 microns and corresponding UTS of approximately 170 ksi. In addition, various forms of the alloys are disclosed including ingots, billets, powders and wire in accord with the described microstructure and physical characteristics.

Titanium alloys

The disclosure provides an aluminum alloy may include iron (Fe) of at least 0.10 wt %, silicon (Si) of at least 0.35 wt %, and magnesium (Mg) of at least 0.45 wt %, manganese (Mn) in amount of at least 0.005 wt %, and additional elements, the remaining wt % being Al and incidental impurities.

Recycled aluminum alloys from manufacturing scrap with cosmetic appeal

A mold apparatus to form a ceramic (or glass) includes a first mold portion having a first coefficient of thermal expansion and a second mold portion having a second coefficient of thermal expansion. In some embodiments, the first mold portion and/or the second mold portion are substantially immiscible with the ceramic material, such as silicon oxide, at a temperature greater than 600&#xb0; C. In some embodiments, the first coefficient of thermal expansion and the second coefficient of thermal expansion are substantially similar to that of the glass or ceramic material. In some embodiments, the first coefficient of thermal expansion is different from the second coefficient of thermal expansion. In some embodiments, the first mold portion and the second mold portion contain a surface coating and a passivation layer.
