Cu‐Ti, Co‐Ti and Ni‐Ti systems: corrosion and microhardness

Journal of Oral Rehabilitation, 1990
SummaryTitanium alloys of 10 wt % ‐72 wt % Cu, 10 wt % ‐80 wt % Co and 20 wt % ‐84 wt% Ni were investigated. Ingots were fabricated in a vacuum/argon tungsten arc furnace. The surfaces of the alloys were examined by optical microscopy and SEM/EDS, and the Knoop hardness values of the alloys were measured.

Ties that Bother - Ties that Matter

Bulletin of Sociological Methodology/Bulletin de Méthodologie Sociologique, 2017
The aim of this article is to show that it is necessary to consider the negative, latent and lost ties, and those with the quality “zero” when studying the formation, change and reaffirmation of residential intentions and decisions. We use the case of Ukrainian immigrants residing in Spain, where we focus on the negative ties and the effects of ...
