Multimaterial structures between aluminum and titanium alloys are a technologically attractive field of research and their increasing use in the transportation sector for weight and emission reduction is part of the ...

The microstructure of metastable beta Ti alloys is a decisive factor that governs their properties and, therefore, the assessment of the relation between the microstructure and the fatigue response means an advance in ...

Talc is a well known lamellar mineral filler much used for mechanical reinforcement of polypropylene (PP) composites. Mineral nanoclay is also a lamellar filler that is gaining much interest due to its reinforcement effect ...

The aims of this work were the microstructural and tensile properties characterization of the hypoeutectic spray formed Al-Si 319 and 380 alloys. The alloys were melted by induction furnace, gas atomized with nitrogen ...

The subject of this work was to study the mechanical properties, based in tensile and impact tests, of two stainless martensitic steels cast under designations of ASTM Standards, namely the CA15 steel, a steel with 12% of ...

In this thesis the Non-linear Resonant Acoustic Spectroscopy Technique used to evaluate the mesoscopic non-linearity was incorporated into the Impulse Excitation Technique, which is extensively applied to the evaluation ...

Aluminum alloys having a particle dispersion in nanometric scale, which present elevated values of mechanical strength at both ambient and high temperatures have been studied for some time. These alloys are known for ...

This work was conducted in four stages, the first to understand the phenomena that affect the 2.25Cr-1Mo steel hot tensile in different conditions, observing their behavior in a wide range of temperature and strain rates, ...

The high speed steels are mostly applied in cutting tools, like drills, cores and top milling cutter. Its microstructure is composed by martensite, with high hardness, strong tempering resistance and disperses carbides on ...
