INFLUENCE OF HEATING RATE ON STABILITY OF AUSFERRITE MICROSTRUCTURE
Austempered Ductile Iron (ADI) is obtained by exactly controlled heat treatment process of nodular cast iron. Ductile iron samples are first austenitised to dissolve carbon, then quenched rapidly to the austempering temperature to avoid the formation of deleterious pearlite or martensite. Resulting ausferrite microstructure consists of acicular fer...

DUCTILE IRON MICROSTRUCTURE DESIGN USING HEAT TREATMENT PROCESSES
Mechanical properties of the ductile iron strongly depend on its microstructure. Different microstructural constituents result in different values of mechanical and ductile properties of ductile iron castings. One of the possibilities to design (define) microstructure of ductile iron castings is an application of different heat treatment processes....
