Dr. Jaroslav Kováčik is senior researcher at Institute of Materials & Machine Mechanics, Slovak Academy of Sciences in Bratislava (Slovakia). His work is devoted to metal matrix composites, focused on physical and mechanical properties of copper – graphite materials. He deals also with powder metallurgical preparation of Ti and Ti composites and using of concentrated solar power for sintering of them and also for solar nitridation of Ti. He is involved in investigation of metallic foams – measurement and modelling of mechanical and physical properties as well.
