2. Microstructural characterization of the A356 alloy in different processing routes used in the thixoforming process
ABSTRACT This work aims to evaluate different routes of raw material production to be used in thixoforming process. The semisolid materials exhibit particular structural characteristics, such the characteristic non dendritic structure. The studies for the production of near-net-shape parts have progressed together with the studies of material weight reductio

6. Diameter dependence of tensile strength by Weibull analysis: Part II jute fiber
The jute fiber is one of the strongest lignocellulosic fibers with applications ranging from simple items such as fabrics and ropes to engineering composites for automobile parts and building panels. Like other lignocellulosic fibers, the jute may have an inverse strength dependence with its diameter. In principle, thinner jute fiber could be comparatively s

7. Charpy impact resistance of alkali treated curaua reinforced polyester composites
Natural fibers obtained from cellulose-based plants are being used as reinforcement of polymer composite owing to both environmental and technical advantages. One important technical characteristic of most lignocellulosic fibers is the bend flexibility, which allows them to resist impact forces. As a consequence, there is an increasing application of these l

10. Study of Tapping Operation of Compacted Graphite Iron With Cemented Carbide Tool / Estudo do processo de rosqueamento com macho de corte de metal duro em ferro fundido vermicular
The use of compacted graphite iron - CGI is growing in the automobile industry, replacing several components that usually are manufactured in grey cast iron. However, due to its poor machinability when compared to grey cast iron, the production cost sometimes is not competitive. Several research about machinability of CGI has already been developed, mainly i
