Results of an experimental study of Cu-Co alloys containing 0.3 to 5.0 wt% Co are presented. A series of solution annealed Cu-Co alloys were analyzed by x-ray diffraction (XRD) and vibrating sample magnetometry (VSM). Each Ka doublet was resolved by fitting a Pearson Type VII profile. Precise lattice parameter as a function of cobalt content deviated significantly from Vegard’s law but was in r...

Zinc represents the most effective and economic corrosion protection especially for steel base materials. Improved corrosion resistance can be achieved by alloying zinc with small amounts (around 1 Yo) of transition metal elements like Co, Ni and Fe. Zn-Fe and Zn-Co alloys containing up to 1.5 Yo of the transition metal were plated using an alkaline and acidic electrolyte respectively. Zn-Ni al...

The title refers to the question addressed in this paper, namely, to what degree if any technology, including nanotechnologies, in the form of products and processes, is capable of contributing to a good life. To answer that question, the paper will develop a meta-normative model whose primary purpose is to determine the essential conditions that any normative theory of the Good Life and Techno...

Titanium alloys, particularly Ti6Al4V, are commonly used in biomedical applications. However, the inclusion of aluminum (Al) and vanadium (V) this alloy can cause cytotoxic effects human body, resulting Alzheimer’s disease cancer. This study compares performance biocompatible alloys containing non-toxic elements, such as tin (Sn) niobium (Nb), which considered safe for implantation. Two sets we...

This study investigates the effects of niobium and molybdenum on FeCoNi alloy, including on the microstructures and hardness of FeCoNiNb0.5Mo0.5 and FeCoNiNb alloys, and the polarization behaviors of these alloys in 1 M sulfuric acid and 1 M sodium chloride solutions. The results in this study indicate that both FeCoNiNb0.5Mo0.5 and FeCoNiNb alloys had a dual-phased dendritic microstructure; al...

Bulk and shear moduli of Cr-Ru alloys in the concentration range 11 < c 5 20 at.% Ru are reported. Phase changes previously observed at 170 K in the magnetic susceptibility of these alloys were not observed in the temperature behaviour of the elastic moduli. Cr can dissolve up to 25 at.% Ru and still retain its bcc structure [I]. The addition of Ru has interesting effects on the magnetic and el...
