Abstract
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.
Claims18
An antiballistic laminate structure comprising:
- an alloy layer comprising a titanium alloy;
- and
- two or more metal matrix composite (MMC) layers, a first MMC layer comprising a titanium alloy reinforced with 40 vol. % to 50 vol. % particles of TiC and a second MMC layer comprising a titanium alloy reinforced with 30 vol. % to 50 vol. % particles of TiB,
- wherein the first MMC layer and the second MMC layer comprise different amounts of TiC and TiB, respectively:
- wherein the titanium alloy of the two or more MMC layers and, optionally, the alloy layer is Ti-6Al-4V;
- wherein the alloy layer and the two or more MMC layers are bonded by applying hot isostatic pressing (HIP):
- wherein each MMC layer is individually fabricated and processed using Blended Elemental Powder Metallurgy (BEPM) treatment prior to applying HIP;
- and
- wherein the antiballistic laminate structure has a porosity of ≤3%, and wherein the two or more MMC layers have a hardness greater than 600 HV.
