It is discussed the use of ADI (Austempered Ductile Iron) for gears. The gears were produced from continuous cast iron bars, heat treated for grade 3 of ASTM ADI Standard A897M-. 06 (UTS >1200 MPa), and compared to carburized steel AISI. 8620 and to induction hardened steel AISI 4140. Tests on gears were made
Austempered ductile iron (ADI) has a microstructure containing spheroidal graphite em- bedded in a matrix which is in general a mixture of phases. Of these, bainitic ferrite and austenite are the most desirable phases, but in many cases small amounts of martensite and/or carbides may also be present in the microstructure.
ZILINA, SLOVAKIA. ABSTRACT: The paper deals with some factors influencing microstructure and mechanical properties of austempered ductile iron (ADI). Final structure and properties of ADI are obtained by exactly controlled process of heat treatment of nodular cast iron. The influence of conditions of isothermal heat
Jan 12, 2018 Introduction. Austempered ductile cast iron (ADI) has gained more attention due to its exceptionally good. blend of low cost, high strength-to-weight ratio, toughness, fatigue strength, and wear resistance, as it.

THE DUCTILE IRON PROCESS. Ductile iron is an iron-based alloy which contains a carbon content that is high enough to exceed its solubility in iron; resulting in the presence of pure carbon or graphite dispersed within an iron matrix. In the case of ductile iron, the shape of the graphite is spheroidal or. Paper 10-129.pdf,

Austempered Ductile Iron (ADI) - A Green Alternative for India. John R. Keough, PEng, FASM. Applied Process Inc. Technologies Div. - Livonia, Michigan, USA. ABSTRACT. In discussions of sustainable or “green" design, the topic of weight reduction is often the first consideration. Immediately, engineers of structural
As expected the low temperature isothermal quenching produced higher strength ADI compare to the same ductile iron but austempered at 350oC. It was discovered however, that low yield strength ADI obtained for short time quenching at 275oC exhibited high strengthening effect while strained in tensile.
Ductile iron casts with a higher silicone content were produced. The austempering process of high silicone ductile iron involving different austempering times was studied and the results presented. The results of metallographical observations and tensile strength tests were offered. The obtained results point to the fact that
