Steels for rolling bearings are important in the world production of special steels. They are used for the production of rolling bodies and rings. Since these are very responsible parts in machine construction, high-quality standards are required for these steels. The service life of rolling bearings, in addition to working conditions also depends ...

Phytoremediation with wild plant species could be environment friendly and economical solution. Selected wild plants like mint, oregano, chamomile, nettle and St. John’s wort, from rural area in Bosnia and Herzegovina, were collected, lyophilized and acid digested for heavy metals analysis. Nickel (Ni), copper (Cu), chromium (Cr), cadmium (Cd...

In this study, aluminum-based composites reinforced with nano-sized boron nitride (BN) were produced by using the casting method. Particle sizes of BN were reduced down to nanoscale via milling for 96 h at room temperature. The casting process ensured a homogeneous distribution of BN within the alloy matrix by melting the aluminum alloy, introducin...
