Abstract:
The Al-Mg 5xxx series aluminum alloy are widely used in industry especially for marine applications since they possess an excellent balance among material such as general corrosion resistance, strength, weldability, weight compared to other Al alloys and formability. These properties are related to the magnesium content and to the applied heat treatments. [..]

Abstract:
The effects of a combined addition of 0.039 % P + 0.015 % Ag as well as a nominal addition of 0.1 % of the de-embrittling elements of copper – B, Mg, Ca, Ti and Zr – to give some variations in contents within the DHP-Cu specification limits on grain size structure at a casting temperature of 1130 °C have been determined and compared to those without the microalloying addition of Ag of 0.015 % obtained at a casting temperature of 1150 °C under TP-1 casting conditions. These results showed that on decreasing the casting temperature from 1150 °C to 1130 °C, the degree of CET increased for DHP-Cu reference with and without microalloying with Ag; the microalloying addition of Ag of 0.015 % to DHP-Cu was essential for grain size control; and that, in comparison to the corresponding DHP-Cu reference cast at 1150 °C and 1130 °C, no further grain refining action was observed due to B, Mg, Ca, Ti and Zr microalloying additions for the conditions studied..

Abstract:
Refractory linings of metallurgical furnaces have two main purposes: to control the heat flow, and to contain high temperature liquids (metal and slag). Through a proper management of heat flows, a layer of slag called freeze lining crystallizes on the internal walls of the furnace thereby protecting the bricks from the very corrosive high temperature liquid slag.

Abstract:
This paper reports on the results of a study of the mechanical properties of sinters made of a new iron-based material, which is becoming increasingly popular in the manufacture of diamond impregnated tools as an economical substitute for cobalt and cobalt alloys. The sinters were formed by hot pressing a mixture of iron and bronze powders. [..]

Abstract:
The effect of ageing on microstructure and Vickers microhardness of fully lamellar Ti-45Al-5Nb-0.2B-0.75C (at.%) alloy was studied. The experimental procedure for preparation of the studied alloy included induction melting of pure elements, centrifugal casting of cylindrical bars and hot isostatic pressing of the bars to eliminate porosity.

Abstract:
The main objective of this paper is to describe the microstructure and mechanical properties of spark plasma sintered tungsten. The indentation tests, which are very advantageous because of their semi-nondestructive character and low requirements on the volume of investigated material, were carried out using Berkovich and spherical indenters.

Abstract:
Hydrogen storage in two Mg-In-C alloys with different indium concentration cIn was studied in the temperature range from 250 °C to 350 °C after five-years-ageing at room temperature. The both alloys show acceptable cycling stability, however, the storage capacity of the alloys decreased from about 5 wt.% H2 to about 2.5 and 3.1 wt.% H2 by higher cIn and lower cIn concentration, respectively after 5 years.

Abstract:
The ultrafine Cu–3 vol.% Al2O3 and Cu–3 vol.% MgO powders with comparable nanocrystalline structures were prepared by thermo-chemical technique and mechanical milling followed by hot extrusion. The study compares an influence of the two different oxide dispersoids on strengthening of the copper matrix after thermo-deformation consolidation of the powders into bulk compacts and annealing of the compacts at elevated temperatures.
