Influence of the microstructure on the degree of sensitization of a duplex stainless steel UNS S31803 aged at 650°C
(2013)
This work evaluates the phase transformations during aging of an UNS S31803 DSS at 650°C and its influence on the DOS. The material was solution treated at 1175°C and then aged at 650°C for times up to 360 h. SEM-BSC images ...
Fatigue life of coir fiber reinforced PP composites: Effect of compatibilizer and coir fiber contents
(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 ...
Study of "napier grass" delignification for production of cellulosic derivatives
(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
(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 ...
Tool wear evaluations in friction stir processing of commercial titanium Ti-6Al-4V
(2013)
This research addresses the application of friction stir welding (FWS) of titanium alloy Ti-6Al-4V. Friction stir welding is a recent process, developed in the 1990s for aluminum joining; this joining process is being ...
