PT Journal AU Andrsova, Z Skrbek, B TI The use of magnetic and ultrasonic structuroscopy for inspection of ADI/AGI castings SO Manufacturing Technology Journal PY 2012 BP 93 EP 97 VL 12 IS 2 DI 10.21062/ujep/x.2012/a/1213-2489/MT/12/2/93 DE austempered iron; ultrasonic structuroscopy; magnetic spot-pole method AB The Austempered Ductile Iron (ADI) and Austempered Grey Iron (AGI) represent the most progressive group of grafitic irons with reference to mechanical properties. These properties depend on accurate observance of default structure, chemical composition and isothermal hardening conditions. ADI/AGI castings are mostly used in automotive industry for moving parts and safety critical items. The production of ADI/AGI in the Czech Republic is insufficient, even if the automotive is the important member of our industrial production. The NDT can be used as the tool of 100% inspection - that provides constant production quality and could support the production of this promising material. This work deals with the development of inspection procedures based on the magnetic and ultrasonic structuroscopy. ER
