Ternary Al-15%Cu-7%Si and Al-22%Cu-7%Si alloys specimens were obtained by transient directional solidification (DS). This technique is able to provide a very large range of cooling rates and microstructures to be correlated ...

Improving the steel processing is a major focus of the metallurgical industry because the need of materials and products with lower weight and more strength, in addition to increasingly stringent specifications imposed by ...

This work aimed to evaluate the possibility of combining spray forming processing with mechanical processing techniques (for instance, extrusion, rotary forging, and equal-channel angular pressing (ECAP)) to be used as ...

During steel ingot solidification, internal voids are expected to be formed in its interior. Such voids, if they stay in the final product after the forging step, will hurt the performance and properties of the final ...

Interested in developing new, and less dependent on non-renewable energy sources, researchers have been looking for different alternatives for energy systems in the recent years. The “Hydrogen Economy” is an alternativ ...

Fe-Cr-Ni-B system alloys with partially amorphous structures can ensure a very attractive combination of mechanical and electrochemical properties, far superior to conventional materials. It can be used, for example, in ...

The efforts to produce automobiles with intense use of aluminum alloys is growing and the 6XXX series of aluminum alloys are important for this scenario. However, the current joining technologies applied in these alloys ...

Stainless steels of the different classes can have their composition modified through the addition of boron, aiming to obtain both amorphous phases and the controlled formation of borides. The formation of amorphous phase ...

The influence of iron additions (0.6, 0.8, 1.2 and 1.5 wt.%) and heat treatment on the microstructure and tensile properties of the 319-aluminum alloy processed by spray forming and rotary swaging was investigated. The ...

Zinc-nickel alloys were electrodeposited on ABNT 4340 high strength steel in chloride acid media. The effect of the electrolyte composition and electroplating conditions on cathodic efficiency, chemical composition, ...
