spalling strengthTime dependences of spalling strength and critical specific fracture energy of some metals under a thermal shock initiated by x€rays of a nuclear explosion are obtained. Under thermal€shock conditions, the durability of metals decreases exponentially as the amplitude of the fracture ...
light weight metalstitaniumaluminiumwirespecific strengthAn alternative deformation technique was applied to a composite made of titanium and an aluminium alloy in order to achieve severe plastic deformation. This involves accumulative swaging and bundling. Furthermore, it allows uniform deformation of a ...
Rolling reduced the original eutectoid microstructure to lamellae of α–Sc and α–Ti with average lamellar thicknesses of 150 nm (Sc) and 120 nm (Ti). The cold-rolled material had an ultimate tensile strength of 942 MPa and a specific strength of 259 J/g. The Sc matrix was oriented ...

[61]. When the specific gravity is less than this range, the concrete mix requires considerable higher amount of cement to meet the requiredstrength. The density increases and does not meet theLWArequirements when the specific gravity value is more than this range[61]. The minimum specific ...
However, because of the harsh processing of metal foams and intrinsic low strength of polymer foams, both are difficult to meet the demand for scalable development of structural foams. Herein, we present a supramolecular metallic foam (SMF) enabled by core-shell nanostructured liquid metals ...
PURPOSE: To produce a high specific strength heat resistant alloy by substituting a part of Ti in an Ni-Ti intermetallic compound utilized as a shape memory alloy by Al and forming its compsn. into a specified one. ;CONSTITUTION: In this allay, the componental ratios are expressed by Ni<...
