A method for producing a chromium sintered body includes a heat treatment step of heat-treating electrolytic chromium flakes at 1,200° C. or higher and 1,400° C. or lower, and a firing step of, after the heat treatment step, filling a container with the electrolytic chromium flakes and firing a resulting filling product by hot isostatic pressing.

A multilayer thin film that reflects an omnidirectional structural color having a reflective core layer comprising a metallic material, a second layer extending across the reflective core layer, a third layer extending across the second layer, and an outer layer extending across the third layer. The multilayer thin film reflects a single narrow band of visible light that is less than 30° measured in Lab color space when viewed from angles between 0° and 45°, and the reflective core layer has a skin depth δ of greater than or equal to 1.0 μm in a frequency range from 20-40 GHz, as calculated by: $\delta =\sqrt{\frac{2\rho }{\left(2\pi f\right)\left({\mu }_0{\mu }_r\right)}}\approx 503\sqrt{\frac{\rho }{{\mu }_{r}f}},$
δ is skin depth in meters (m); ρ is resistivity in ohm meter (Ω.Math.m); f is frequency of an electromagnetic radiation in hertz (Hz); μ.sub.0 is permeability; and μ.sub.r is relative permeability of the metallic material.

The present invention relates to a method for producing metal-comprising geometrically complex pieces and/or parts. The method is specially indicated for highly performant components. It is disclosed a method for the production of complex geometry, and even large, highly performant metal-comprising components in a cost effective way. The method is also indicated for the construction of components with internal features and voids. The method is also beneficial for light construction. The method allows the reproduction of bio-mimetic structures and other advanced structures for topological performance optimization.

A stent comprising a cobalt-based alloy comprising 18-50 weight % cobalt (Co), 10-25 weight % chromium (Cr), 10-15 weight % tungsten (W), 0-2 weight % of manganese (Mn), 0-3 weight % iron (Fe), and 10-65 weight % metal member selected from a platinum group metal.

Disclosed herein are improved chromium carbide alloy which possess improved properties as related to previous developments. The utilization of aluminum in the alloy can enhance the high temperature oxidation resistance. Embodiments of alloys were designed to simultaneously possess 1) a low liquidus temperature which enables easy atomization on an industrial scale, and 2) a microstructure of a gamma matrix and Cr.sub.7C.sub.3 carbide precipitates which enables high temperature stability and retention of advantageous properties at high temperatures.
