IPMINFRA represents unique research infrastructure for study and testing of advanced materials used in engineering applications. The Infrastructure covers the area of long-term mechanical tests (fatigue of materials, creep and fatigue/creep interaction and fracture and failure analysis in broad temperature range) and characterisation of material structure and its changes during loading. This infrastructure is essential for power generation industry (development of materials for nuclear reactors, thermal power stations), for transportation (materials for turbochargers, aircraft turbines, axles, high loaded parts of vehicles) and medical applications (materials for implats). IPMINFRA follows long-term tradion of Institute of Physics of Materials ASCR, v. v. i. in the study of physical nature of processes taking place in materials during creep, fatigue, creep/fatigue and under other types of mechanical loading, study of structure of materials and selected thermodynamic, diffusion and magnetic properties. The unique laboratory core of IPMINFRA is formed by 35 creep machines with testing range up to 1600°C, 10 fatigue testing machines (with testing range from -180°C to 950°C) and 5 electron microscopes. This equipment together with a number of other devices belonging to IPMINFRA makes it possible to realize long-term and wide range testing of advanced materials and materials used in new engineering applications. The infrastructure IPMINFRA is of utmost importance and highly beneficial for academic research and education as well as for applied research of small and medium enterprises.
