Investigation on the effect of a compatibilizer on the fatigue behavior of PP/coir fiber composites

Bettini S.H.P.; Antunes M.C.; Magnabosco R. (2011)

The mechanical behavior of polypropylene (PP) and 30 wt% coir fiber reinforced PP composites, with and without compatibilizer, were assessed through monotonic (tensile and bending) and cyclic (fatigue) tests. Fatigue load ...

Mean strain influence in low cycle fatigue behavior of AA7175-T1 aluminum alloy

Salerno G.; Magnabosco R.; Moura Neto C.d. (2007)

This work evaluates the mean strain influence on total number of cycles to fatigue failure of AA7175-T1 aluminum alloy, based on empirical relationships developed by SWT, Morrow and Walker, that were used to adjust the ...

Fatigue life of coir fiber reinforced PP composites: Effect of compatibilizer and coir fiber contents

Antunes M.C.; Moraes D.V.O.; Magnabosco R.; Bonse B.C.; Bettini S.H.P. (2013)

The fatigue behavior of polypropylene/coir fiber composites was investigated. Composites were prepared according to an experimental statistical design, in which the independent variables coir fiber and compatibilizer content ...

Toughness of Two HSLA Steel Sheets

Magnabosco R.; Rossetto L.C. (2003)

This paper presents a study concerning the toughness anisotropic behavior of two high-strength low-alloy steel sheets having ferrite-martensite (dual-phase) and ferrite-perlite grain-refined structures. The anisotropic ...

Sensitization and pitting corrosion resistance of ferritic stainless steel aged at 800°C

Paroni A.S.M.; Alonso-Falleiros N.; Magnabosco R. (2006)

This work investigates the influence of sensitization conditions on pitting corrosion resistance of ferritic stainless steel UNS S43000 aged at 800°C between 10 min and 320 min. UNS S43000 steel is susceptible to intergranular ...

Sigma phase formation and polarization response of UNS S31803 in sulfuric acid

Magnabosco R.; Alonso-Falleiros N. (2005)

For a better understanding of the relationship between the microstructure of UNS S31803 duplex stainless steel (DSS) and the shape of the polarization curves, this study evaluated the influence of the microstructure on the ...

Study of "napier grass" delignification for production of cellulosic derivatives

De Araujo Morandim-Giannetti A.; Albuquerque T.S.; De Carvalho R.K.C.; Araujo R.M.S.; Magnabosco R. (2013)

Recently, much research on the evaluation of new cellulose sources has been developed. In this context, a promising source is "napier grass", which contains 30.40% lignin, 36.34% cellulose, and 34.12% hemicellulose. In ...

Influence of sigma phase formation on pitting corrosion of an aged uns s31803 duplex stainless steel

Dos Santos D.C.; Magnabosco R.; De Moura-Neto C. (2013)

The main purpose of this contribution was the study of the relation between sigma formation and pitting corrosion resistance of a UNS S31803 duplex stainless steel aged at 850°C. Solution-treated samples were isothermally ...
