Abstract In this study, a novel Chromium steel grade (COIN2) is produced as result of new composition and an innovative heat treatment. This COIN2 evolves from the P92 other recently created by authors (COIN), represents enhancement hardness, tensile properties, creep behaviour with respect to them, which validates metallurgical strategy used for further research in order increase efficiency po...

An Aramaic-inscribed object made of copper-alloy was discovered in 1993 the south-western part Tulûl Mas‘ud (Moshav Elyakhin) and has recently been studied using an archaeometallurgical approach. Based on visual testing multifocal light microscopy observation, probably produced a nearby workshop, with inscription engraved sharp tool during production process. Given larger assemblage inscribed a...

Applications of nanowires into future generation nanodevices require a complete understanding of the mechanical properties of the nanowires. A great research effort has been made in the past two decades to understand the deformation physics and mechanical behaviors of nanowires, and to interpret the discrepancies between experimental measurements and theoretical predictions. This review focused...

Understanding the metallurgical joinability of pure Mg and Fe their interfacial microstructure lays foundation for deciphering complicated mechanism joining various magnesium alloys steels in applications. Pure were successfully joined to form a bond first time using friction stir assisted scribe technique. Through detailed characterization, we found that two immiscible metals are bonded by cri...

A lot of metallurgical processes take places in shaft furnaces, where reacting gas carrying powders flows up in packed bed of descending metallurgical materials. Gas + powder two phase flow in fixed packed bed has been investigated by author for many years 1 . At present author undertakes the investigations with moving bed. Physical model with glass bed and glass powders was constructed. The ex...

The basic areas of devices condition management through Autonomous and Professional Maintenance are described here. Mentioned areas of activities are per...

BACKGROUND/OBJECTIVES The purpose of this study was to compare the mechanical, structural, and aesthetic properties of two types of aesthetic coated nickel-titanium (NiTi) wires compared with comparable regular NiTi wires in the as-received state and after clinical use. MATERIALS/METHODS Sixty one subjects were randomly assigned to four groups (N = 61), two groups of coated wires and two grou...

Bożena Gajdzik, The Silesian University of Technology, Faculty of Materials Science and Metallurgy, Katowice, Poland The topic of the article is the change in action strategy of metallurgical enterprises in time of economic slowdown. The fi rst part of article presents results of literature analyses, opinions of scientists concerning changes in behaviours of enterprises in time of bad conjunctu...
