In this work we studied the response of newly developed armored steel plates PROTAC 500 to the ballistic testing with armored piercing bullets with a core of tungsten carbide, charge 7.62 mm. Interactions between the bullets and the steel plate was investigated by standard metallographic and mechanical testing methods. We were interested in the geo...

Innovative idea of the device for detecting microstructure changes, concept and construction was carried out and controlled by authors of this article in cooperation with Slovenian industry. Since the electrical resistance is one of the most structurally sensitive properties of the materials, we used its measurement to detect microstructural change...

Partially crystalline metallic glass ZrCu was prepared in the form of ribbons by melt-spinning. The chemical composition and homogeneity of the samples alongside partial crystallinity with the existence of an amorphous matrix was confirmed. The measured value of microhardness shows a nonlinear dependence with the increase of Cu. By adding a small f...

When considers about design/development of products then it must be objectify one of the following aspects, development of completely new products, development of new product lines, addition of existing product lines, improvements and revisions of existing products, repositioning and cost reduction. When you design a product, it is necessary to mak...

In this paper the synthesis of nanoparticles of iron oxide from aqueous solution was carried at temperatures of 10, 20, 30, 40, 50 and 60 °C and with a different precipitation rate controlled by addition of a precipitating agent. The possibility of synthesis of ferrofluid with different ratios of reactants (FeCl2 and FeCl3 solution and NH4OH) w...

This study has examined the process of sintering of Mg0 samples (80 % precipitation) obtained from seawater at a temperature of 1600 ºC with time until the sintering temperature is obtained, in order to examine their properties (density, porosity) and chemical composition after sintering. The prepared magnesium oxide samples are distinguished ...

In the process of production of iron and steel substantial amounts of fuel and raw materials are consumed. Metallurgical coke as fuel, reducing agent and material that provide gas flow trough blast furnace processes must possess certain properties in terms of strength, due to expected changes in the conditions of high temperature environment. Deman...

This paper describes the analysis and rationalization of energy consumption in gray iron foundry CIMOS TMD Casting Zenica. Based on results of analysis the key points are defined rationalized and measures proposed to reduce energy consumption, and therefore reduce production costs. The most significant share of energy consumption, and therefore in ...

Steel shot is used in foundries as a means for mechanical cleaning of castings. Due to wear (mechanical damage) there is a change in size of shot. After some time of use steel shot it becomes unusable for shot blasting process and becomes waste. Studies have shown that this type of waste has good adsorption properties and it is suitable adsorbent f...
