Environment safety measurements have resulted in use of peroxide as bleaching chemical in place of chlorine and chlorine dioxide. Concentration and composition of chemicals affects corrosion aspects, the suitability of existing plant metallurgy and materials of construction of bleach plants. Accordingly long term immersion and electrochemical corrosion tests were conducted on stainless steel 30...

In most of the engineering applications, such as mining, metallurgy, agriculture; equipments are failed by the abrasive wear. The data as obtained form ministry of Research and Technology indicates that the percentage cost of abrasive wear in federal republic of German in metallurgy industry is 40%, mining industry 30%, agriculture 20% and production engineering 10%, and so the material selecti...

Strong steels also have to be tough and hence rely on fine microstructures such as bainite or martensite, produced commercially by continuous cooling transformation. Depending on the detailed requirements, the steel-design process may explicitly require other higher temperature phases to be absent in the final microstructure. Such a procedure can be made easier by the availability of a good met...

Walke, Faculty of Biomedical Engineering, Silesian University of Technology, Zabrze, Poland Quality of applied guide wires conditions the course of treatment and its success to a great extent. In order to simulate conditions that can be found in blood vascular system samples were...

Metallurgical design of microalloyed steel used to be a challenge due to its multivariate nature. Over ten kinds of microalloying elements and multi-step processing routes have complex interactions and different contributions to the final mechanical properties. Data-driven model is able to throw a rapid insight into the composition-processing -property correlation of steel metallurgy in a syste...

B. Gajdzik, The Silesian University of Technology, Faculty of Materials Science and Metallurgy, Katowice, Poland The objective of this publication was to present the results of prognoses for steel production volume in the world. This work was created on the basis of statistical data. The volume of total steel production in the world from 2000 to 2015 was used in order to create the prognosis. T...

In this study, Ti-5Al-2.5Fe alloy was prepared by powder metallurgy. The elemental titanium, aluminum, and iron powders were mechanically alloyed for 10 h in a vacuum atmosphere. A stainless steel jar and stainless steel balls were used for mechanical alloying. The alloyed powders were then sintered by vacuum hot pressing at 950 °C for a soaking time of 30 minutes. Pure titanium was also sinter...
