Fabrication of High-Strength, Lightweight Metals for Armor and Structural Applications

The project will develop a new processing technology of equal-channel angular extrusion (ECAE) providing semi-continuous multipass ECAE without necessity for billet cleaning, reshaping and preheating between passes. This approach turns ECAE into an effective operation that can be applied at large metallurgical scale and to massive production. Followed rolling, low-cost bulk products such as plates and sheets with ultra-fine grained and nano structures having superior properties are fabricated for different applications. Particular applications are high strength aluminum alloy armor plates and rolled products for precision forging, panel forming, superplastic forming and deep drawing in defence, aerospace, automotive and others industries.
