Effect of Vacuum Hot-Press Process on the Sintered Characteristics and Mechanical Properties of a High-Density Cr-31.2 Mass% Ti Alloy [PDF]

Archives of Metallurgy and Materials, 2018
In this study, two different compositions of submicron-structured titanium (760 nm) and micron-structured chromium (4.66 μm) powders were mixed to fabricate Cr-31.2 mass% Ti alloys by vacuum hot-press sintering.

The Performance of Different Etchants on the Carbides of Ni600 and Ni625

Metals
Nickel-based alloys that contain chromium are widely used in corrosion-resistant applications in industry, but they are sensitive to the environment when the passive chromium oxide layer is damaged. In Ni600 and Ni625 alloys, precipitates can deplete the
