The primary objective of the article is to present an innovative workstation and the test results related to iron-based bulk metallic glasses made by pressure casting into a copper die that is cooled with Peltier modules. A production of bulk metallic glasses by pressure casting into a copper die, including an innovative cooling method is presented in this article. The equipment for the casting, including a modern high-frequency induction heater and a control-measuring apparatus, which enables the repeatability and maintenance of the process parameters, is discussed. Semiconductor Peltier modules for cooling the molds are presented. The tests show that the semiconductor Peltier modules are a suitable substitute for the water cooling of the molds. They enable the casting at 0°C of the molds. Additionally, the ecological and economic aspects of the introduced new methods are presented. The application of the innovative cooling technology also has an influence on a simplification of the equipment construction for the casting process. The test results for the bulk metallic glasses based on iron and obtained with the designed devices are presented in this paper. A structure analysis using X-ray examination and microscopic observation was performed. The diffraction pattern and microscopic observation revealed that the studied as-cast Fe-Co-B-Si-Nb alloy is in the amorphous state. The test results confirmed the amorphous structure of the obtained materials.

V~lanku je predstavljena izdelava masivnih kovinskih stekel s tla~nim litjem v bakreno orodje z inovativno metodo ohlajanja. Obravnavana je oprema za litje, ki uporablja moderen visokofrekven~ni indukcijski grelnik, opremljen s kontrolno-merilnimi napravami, ki omogo~ajo ponovljivost in vzdr`evanje procesnih parametrov. Predstavljeni so polprevodni{ki Peltierjevi moduli za hlajenje kokile. Preizkusi so pokazali, da so polprevodni{ki Peltierjevi moduli primeren nadomestek vodnega hlajenja kokil. Omogo~ajo ulivanje pri temperaturi kokile 0°C. Dodatno so predstavljeni {e ekolo{ki in ekonomski vidiki nove metode. Uporaba inovativne tehnologije hlajenja vpliva tudi na poenostavitev konstrukcije naprave za ulivanje. V tem delu so predstavljeni rezultati preiskav masivnih kovinskih stekel na osnovi`eleza, dobljenih z novo konstruirano napravo. Analize strukture so bile izvr{ene z rentgensko preiskavo. Posnetki difrakcije in mikroskopska opazovanja so odkrila, da je zlitina Fe-Co-B-Si-Nb v litem stanju amorfna. Rezultati preiskav so potrdili amorfno strukturo dobljenega materiala. Klju~ne besede: kovinski materiali, masivna kovinska stekla, Peltierjevi moduli, zlitine na osnovi Fe, tla~no litje v bakreno kokilo
The main aim of this work is to present the structure and topography of the Fe37.44Co34.56B19.2Si4.8Nb4 laser weld. A laser welding has been applied to increase the capability of using these materials in the industry. The amorphous and amorphous-crystalline phase were confirmed by X-ray analysis, atomic force microscopy, and high resolution transmission electron microscopy tests. The detailed topographic analysis revealed that the heat affected zone show a roughness characteristic of the crystalline phase and a smooth surface in the fusion zone.
