Abstract. Trend of simultaneous improvement such mechanical metal properties as strength, hardness and ductility remains popular. Asymmetric accumulative roll bonding is a method severe plastic deformation that can create large shear deformations. These deformations in its turn are responsible for increase properties. Initially computer modeling was carried out to study the influence kinematic ...

This paper reports a study of multilayer nanolamellar Mo/Nb/TiNi composites designed by the principle martensitic transformation enabled lattice strain matching. The composite was fabricated hot packaged accumulative roll bonding (PARB) and wire drawing. showed an apparent yield strength ~1200 MPa recoverable superelastic ~7%, with mechanical damping ~62 MJ/m3. Both Nb Mo nanolamellae sandwiche...

The local laser heat treatment of precipitation hardenable aluminum alloys enables the tailoring of the materials properties and the manufacturing of lightweight and crash-proof components for the body in white. For conventional aluminum sheet metals and profiles the formability is enhanced by an indirect approach. Thereby specific parts of the products are softened in order to improve the mate...
