Metais amorfos são materiais que têm sido intensivamente estudados por apresentarem interessantes propriedades físicas, entre elas principalmente resistência a corrosão e fadiga, possibilitando assim a sua aplicação em ...

This thesis presents the development of a new criterion which can indicate new compositions for amorphous metallic alloys. This new criterion was based on dense packing of spheres combined with the lambda criterion through ...

The selection of good glass forming compositions is not a simple undertaking and many groups work on models and theoretical approximations in order to predict or at least guide the laborious and expensive experimental ...

Ni-based amorphizable alloys in the bulk form show a good combination of properties, with high mechanical strength and hardness, good ductility and excellent corrosion resistance. These alloys have been used in recent ...

Searching the development of bulk metallic glasses the research takes two directions, the development of alloys with a high glass forming ability and development of new processes or improving existing processes. In this ...

Glass forming ability (GFA) is one of the big issues to obtain large bulk metallic glasses, which are composed of three or more elements. Regardless of an increasing theoretical understanding of glass formation, taking a ...

Amorphous Iron-based alloys can be processed in such a way that, if well designed, it can ensure an attractive combination of mechanical and electrochemical properties, particularly in petrochemical industries where ...
