Connecting Rod. The connecting rod connects the piston to the crankshaft, and consists of the crank(big end),pin (small end),and shank.

The connecting rod small end, which is connected to the piston via the piston pin, transmits the combustion pressure of the. Austempered ductile iron (ADI) was first commercialized in the early s and has since become a major industry.

Process [ edit ] The most notable difference between austempering and conventional quench and tempering is that it involves holding the workpiece at the quenching temperature for an extended period of time.

Microstructure of (a) as cast ductile iron showing ferrite and islands of pearlite, (b) ductile iron austempered at °C showing acicular ferrite and retained austenite, (c) ductile iron austempered at °C and (d) ductile iron austempered at °C, notice that the ferrite has become more by: Austempered Ductile Iron, which is a heat treated Ductile Iron (DI) with an extraordinary ratioof tensile strength to density.

Based on the heat treatment parameters, a high tensile strength (normed between and MPa) and ductility (up to more than 10%) can be reached, meaning that properties comparable to forged steels like.

Uma, J. Simha, K. Narasimha Murthy. Foundrymen's Society Annual Conference. Looking back on the first four decades of Ductile Iron reveals the classical pattern of the research, development and commercialization of a new material.

In the early years INCO, the patent holder, introduced Ductile Iron to designers and engineers by distributing technical literature and conducting Size: 3MB. The properties of ductile iron can be improved by alloying treatment or by subjecting casting to austempered heat treatment which finally results in the bainitic matrix in the iron.

The iron subjected to austempering heat treatment is referred to as austempered ductile iron or simply ADI. An investigation was carried out to examine the influence of microstructure and chromium on the tensile properties and plane strain fracture toughness of austempered ductile cast iron (ADI).

The investigation also examined the growth kinetics of ferrite in these alloys. Compact tension and round cylindrical tensile specimens were prepared from ductile cast iron with Cr as well as without by:   ASM Proceedings, “1st International Conference on Austempered Ductile Iron: Your Means to Improved Performance, Productivity and Cost,” April 2–4, Cited by: 3.

Today, it Cited by: The conventional grinding wheels employment is an economically viable alternative on Austempered ductile iron (ADI) grinding. The machining of this iron is in most cases performed with superabrasive grinding wheels, requiring machine tools with higher costs.

The ADI grinding with conventional grinding wheels can produce work results comparable to the superabrasive grinding wheels, followed by Author: Lucas Benini, Walter Lindolfo Weingaertner, Eckart Uhlmann.

Austempered ductile iron (ADI) is a relatively new engineering material with exceptional combination of mechanical properties and marked potential for numerous applications [1]. The attractive properties of ADI return to its distinct and unique microstructure, which consists of fine acicular ferrite within carbon.

Austempered Ductile Iron [ADI] provides a range of high strength irons with higher ductility and toughness. Through the work hardening characteristics of the matrix these irons have an exceptional blend of wear properties and toughness.

These irons have the advantage that the base iron is readily machinable before heat treatment allowing hard. Google Scholar yielded some interesting results.

Hayrynen, "Another Avenue for Ductile Iron Foundries", Modern Casting Magazine, August This article describes the designation of ductile cast irons according to the ASTM International designation system and reviews standard-grade ductile cast irons. An overview of the most commonly used standards related to designation and specification of ductile cast iron is presented in a table.

% Ni alloyed iron austempered for 10 minutes (Fig. Figure 2 illustrates the effect of ausforming to 25% RH on the refinement of the microstructure. Nickel promotes free austenite and after austempering for very short times, the residual unreacted austenite transforms to martensite on cooling to room temperature (Fig.

Austempered ductile iron (ADI) is finding an ever increasing worldwide market in the automotive and other sectors.
