Ion nitriding is a glow discharge process that is used to induce surface modification in metals. It has been applied to 316-L austenitic stainless steel looking for similar benefits already obtained in other steels. An austenitic stainless steel was selec...

The relationship between the degree of sensitization and the corrosion resistance of austenitic stainless steel has been reported since long time, however this relationship does not account for all the experimental results reported on the literature. The ...
Sensitization is a cause of corrosion that has been widely studied in austenitic steels; however, the relationship between sensitization and mechanical properties of steel is less known. Therefore, the objective of this work is to study the mechanical pro...
The intergranular stress cracking of welded joints of austenitic stainless steel, AISI 304, is a serious problem in BWR type reactors. It is associated with the simultaneous presence of three factors; stress, a critical media and sensibilization (DOS). EP...
Corrosion susceptibility under stress of AISI 304 steel sensitized in a sodium thiocyanate solution has been studied and results were compared with those obtained with solutions of thiosulfate and tetrathionate. Sensitized steel type 304 is highly suscept...
The relationship between: microstructure-heat treatment, microstructure-mechanical properties, microstructure-corrosion resistance make that the study of the microstructure of metals and alloys be a powerful tool either in technical-scientific research as...
Phosphate coatings are inorganic crystalline deposits laid down uniformly on properly prepared surfaces by a chemical reaction with the treated base metal. The reaction consists in dissolving some surface metal by acid attack and then causing surface neut...
This paper is part of a series which corresponds to the carbon steel behaviour as construction material for Girlder sulfide (G.S.) heavy water plants. The present work analyses the iron concentration study during passivation in the passivating fluid. At t...

The purpose of the publication is to explain in an easy way the traditional process of steel manufacturing, and to promote the interest of the foundrymen working without large investment.
Many tropical fruits are rich in anthocyanins, though limited information is available about the characterization and quantification of these anthocyanins. The identification of anthocyanin pigments in four tropical fruits was determined by ion trap mass spectrometry. Fruits studied included acero...
