In the present work, deoxidation and refining of 316LVM steel (Low carbon Vacuum Melted) during the vacuum induction melting process was studied. This grade of stainless steel is one of the most import...

poly (propylene fumarate) (ppf), a linear unsaturated polyester consisting of alternating propylene glycol and fumaric acid units, can be cured in vivo to fill the skeletal defects with minimal surgical intervention. many different methods have been reported for synthesizing ppf, but none of them gives a clear method. the present paper introduces two new methods in ppf synthesis: modified reflu...

-s 1 WELDING JOURNAL ABSTRACT. Brazement design is a critically important characteristic of a brazed joint structure. The design is responsible for reliability and proper service behavior of brazed products. According to the state of the art, a good design provides not only required properties of the brazed structure, but also a very high technological suitability. The latter is necessary in or...

persian sturgeon (acipenser persicus) is one of the most important fish in caspian sea and demand for its fillets is considerable, study to improve the packaging and protect their quality during storage is necessary. in this study persian sturgeon fillets were packed under 30% vacuum then freezed and effect of this packaging method on decreasing and delaying lipid rancidity was studied by measu...

Dissimilar metals have found wide use in electric power generation, electronics, reactors, nuclear, petrochemical, chemical industries, civil construction, vessels, and heat exchange as well several other industries. TIG welding (Tungsten Inert Gas Welding) is a type of that uses tungsten the electrode material not consumed. Brazing way joining metal materials through heating process with an ad...
