During the last ten years there have been many studies of the physical and chemical properties of synovial fluid in relation to the production and prevention of joint lesions. These researches on the properties of normal human synovial fluid have nearly all been done on specimens obtained post morteFn, all other work on the normal having been done on fluid obtained from the joints of cattle. Fu...

The widespread application of thermoplastic polymers in different aspects of industries has motivated researchers and companies to improve and upgrade their forming, joining and assembling processes to overcome their limitations. One of the newest joining methods of thermoplastics is friction stir welding which is based on frictional heat generated through contact between a rotating tool and th...

The current work was carried out to characterize welding of AISI 310 austenitic stainless steel to Inconel 657 nickel-chromium superalloy. The welds were produced using four types of filler materials; the nickel-based corresponding to Inconel 82, Inconel A, Inconel 617 and austenitic stainless steels 310. Of the two joints involved, this paper describes the choice of welding consumables for the...

Both Ti-6Al-4V and 316L stainless steels are widely used as engineering alloys. Fusion welding of these two alloys is not easily possible due to their incomplete solubility in each other. Brazing is one of the best choices for joining dissimilar alloys. In this study, wettability experiments were done at 940 and 970 ºC for 5, 15 and 30 min. Also, joining of these two alloys was carried out at 9...
