Titanium-Based Laminate Structures Fabricated Using Blended Elemental Powder Metallurgy and Hot Isostatic Pressing
The present disclosure is directed to a laminate structure and method of making the laminate structure. The laminate structure includes an alloy layer and one or more metal matrix composite (MMC) layers. The alloy layer includes a titanium alloy. Each MMC layer includes a titanium alloy reinforced with 5 vol. % to 50 vol. % particles of TiC or TiB. The alloy layer and the one or more MMC layers are joined by applying hot isostatic pressing.
Thick Al—Mg alloy rolled product suitable for armor plate applications
The disclosure relates to an aluminum alloy plate having a final thickness of 3 inch or more, and a method for manufacturing same. In the method, an aluminum alloy with a chemical composition of in weight percent: Mg 4.0 to 5.2, Mn 0.4 to 1.0, Zn0.3, Zr0.3, Cr0.3, Ti0.3, Fe<0.50, Si<0.45, Cu<0.25, other elements and unavoidable impurities each <0.05 total <0.20 balance aluminum, is cast, preheated and/or homogenized, hot rolled, cold rolled with a cold rolling reduction of 3 to 10%, and stretched directly after cold rolling with a permanent elongation of 0.7 to 5% in the direction of stretching.
