The present study compares castability and mechanical performance among alloys of c.p. Ti, Ti-6Al-7Nb and a newly-developed Ti-15Mo-1Bi in regard to their as-cast state. Experimental results indicate that average cast length of Ti-6Al-7Nb appears a little lower than c.p. Ti and Ti-15Mo-1Bi, although the differences are not significant. C.p. Ti has an hcp phase of lath-type morphology with serra...

Application of a systems approach to the computational materials design led to the development of a high performance stainless steel. The systems approach highlighted the integration of processing/structure/property/ performance relations with mechanistic models to achieve desired quantitative property objectives. The mechanistic models applied to the martensitic transformation behavior include...

Abstract Over the last decades, additive manufacturing (AM) has become principal production technology for prototypes and components with high added value. In of metallic parts, AM allows producing complex geometry a single process. Also, admits joining elements that could not be realized traditional methods. addition, using other types processes like reticular structures in heat exchangers. A ...

Abstract The evolution of microstructure in relation to dating and nationality origin was investigated twenty-four cast iron objects street furniture produced between XIX XX centuries United Kingdom, France, Italy. Chemical composition the metalworks evaluated by glow-discharge optical emission spectrometry. Fragments from irons were analyzed microscopy scanning electron with energy-dispersive ...

Additive manufacturing (AM) of metals can be broadly accomplished via two defined technologies: powder bed fusion and directed energy deposition. During AM fabrication, the melted feedstock material experiences fast thermal cycling due to layer-by-layer deposition process resulting in microstructures properties that are drastically different from traditionally manufactured parts. For become a v...

A fine and equiaxed solidification process delivers multidimensional benefits to Mg-alloys, such as improved castability, reduced casting defects, enhanced mechanical properties, increased corrosion resistance potential for recycled contents. Despite extensive research on grain refinement of Mg-alloys in the last few decades, currently, there is no effective refiner available refining Mg-Al all...

The low mass and high specific stiffness of Mg alloys make them particularly interesting as means transportation. Due to further desirable properties, such good machinability excellent castability, have gained acceptance castings in high-volume applications, gearbox housings automotive steering wheels. However, forming processes, extrusion forging, find little no industrial use at the moment. r...
