Titanium and its alloys, particularly Ti6Al4V, are widely used, especially in aerospace andmedicine due to their relatively low density, high strength, and good corrosion resistance. However,there are formidable challenges in casting, forming, and machining titanium alloys, which result infinal products that are considerably more expensive. Additiv...

Many alloys exhibit the shape memory effect, but only the Cu-Al-Zn, Cu-AI-Ni, and Ni-Ti alloysare presentand of commercial importance. The greatest use of these alloys is in biomedicine(filters, orthodontic implants, guide wires for catheters, etc.). Shape-memory alloys may be foundin sensors in automobiles, consumer products, and generally in smar...

Heavy metals can enter into rivers through industrial and consumer waste, activities of acidic rainto soils, etc. Long-term exposure can result in damaging: mental and nervous function, bloodcomposition, lungs, kidneys, liver, and other vital organs. Estimating a health risk based on thecontents of heavy metals found in river Bosna was the aim of t...

The electrocoagulation with zeolite addition was used to treat compost leachate. The effects ofdifferent current densities and zeolite particle sizes on electrode dissolution, electrode surfacecondition, and removal efficiency were investigated. The surface of the electrodes was analysedby optical microscope, while the consumption of the aluminium ...

Considering the toxic properties of heavy metals and their effects on the environment, there is anincreasing interest in studying their interactions with different ligands and searching forpossibilities to remove those ions from the environment. Compared to other ligands, crown etherspossess the highest selectivity as ligands for metal cations, due...

Some specific aspects in positioning of the re/heating furnaces at a layout of the modern rolling mills are presented in this paper. Theoretical and practical solutions in the above mentioned (further a.m.) field are presented for both, wire rod and light section bar mills. Some of the a.m. aspects are explained, confirming that even unexpected sol...

Proper calibration of the device is important to prevent potential sources of error, which ensures that the test results most effectively represent the value of the sample being tested. In microhardness testing, the loading force does not exceed 1.96 N. The test surface requires a more complex metallographic preparation, and the smaller the injecti...

The paper examined the changes in properties of conventional castables composed of a mixture of calcium-aluminate cement and chamotte caused by changes in the particle size distribution. Properties of castable with 20 % cement and „as received“ chamotte were compared with castableofparticle size distribution adapted to the calculated di...
