    Abstract: Methods for manufacturing rotary target materials that allow a material to be cast in a melting zone of a casting vessel while the vessel is rotated such that a melting zone is below a casting zone. The vessel is sealed and the pressure inside the vessel is reduced and the exterior of the vessel is heated. The melting zone of the vessel is heated to a temperature that melts the material and releases any trapped gasses which can be pumped out using the vacuum pump. Once the melting zone and molten material have reached a specified temperature, outgassed, and the casting zone has reached a temperature to maximize adhesion and reduce voids and defects, the vessel is rotated until the melting zone is directly above the casting zone to transfer the material from the melting zone to the casting zone.

    Abstract: A method for preparing aluminum foam sandwich material by rotating friction extrusion and electromagnetic pulse hybrid process includes: step 1: preparing the filler; step 2: processing the filler to prepare a plurality of preforms; step 3: clamping and fixing the plurality of preforms to form a preform assembly; step 4: welding the panel on the surface of the preform assembly to form an non-foaming sandwich material; step 5: heating and foaming the non-foaming sandwich material through a foaming mold; step 6: insulating the foaming mold after completion of foaming; injecting cooling water into the foaming mold after completion of insulation to maintain pressure and shape, forming the aluminum foam sandwich material of the required shape. The aluminum foam sandwich material produced by this method has good interface bonding, no adverse interface reaction, high bending resistance, impact resistance, and excellent sound absorption and insulation properties.

    Abstract: 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 α-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.

    Abstract: A method for producing a device having at least one internal feature includes manufacturing an internal volume of the internal features out of a first material, disposing the internal volume in a parent material that has a higher melting point than the first material, causing the internal volume to melt within the parent material, and allowing at least a portion of the first material to diffuse into the parent material, thereby leaving behind the at least one internal feature within the parent material.
