In the technical laboratories, we check production processes, carry out investigations into material and process development, examine damage and the consequences of heat treatment. To check the quality, we create samples and do mechanical-technological and metallographic tests in compliance with national and international standards.
The mechanical trials include, among others, tensile tests, notched bar impact bending tests, fracture toughness tests, hardness tests and creep rupture tests. As non-destructive testing methods we use magnetic field measurements and ultrasonic inspection.
For the metallographic examinations such as microstructure, grain size, degree of purity, degree of decarbonisation and phase analyses, we use light microscopes, automatic image analysis systems and opto-electronic equipment such as scanning electron microscopes with EDX and micro-sensor.
