Nickel cast irons

An important appHcation of MMCs in the automotive area is in diesel piston crowns (53). This appHcation involves incorporation of short fibers of alumina or alumina—siHca in the crown of the piston. The conventional diesel engine piston has an Al—Si casting alloy with a crown made of a nickel cast iron. The replacement of the nickel cast iron by aluminum matrix composite results in a lighter, more abrasion resistant, and cheaper product. Another appHcation in the automotive sector involves the use of carbon fiber and alumina particles in an aluminum matrix for use as cylinder liners in the Prelude model of Honda Motor Co.

The ecological and economic consequences of recovering 4500 lbs. per month of a 32% ferro-nickel alloy are impressive. This material can be saleable feedstock to industries producing wrought stainless steel, stainless steel castings, and high-nickel cast irons. Instead of a cost and liability, we now have a profit center.

Hydroxamic acids were utilized in determinations of vanadium in steel and rocks [106,107], nickel, cast iron, and titanium alloys [40], natural waters, and petroleum [42]. The crown hydroxamic acid has been applied for determining V in ores, steel, blood, and environmental samples [108],... 

In addition, there are a number of alloy cast irons, many of which have improved corrosion resistance and substantially modified mechanical and physical properties. Generally, cast iron is not a particularly strong or tough structural material. Nevertheless, it is one of the most economical and is widely used in industry. Its annual production is surpassed only by steel. Iron castings are used in many items of equipment in the chemical-process industry, but its main use is in mechanical engineering applications automobile and machine tools. Some of the best known classes, fisted below, include the high-silicon and nickel cast irons.
