...Abstract Abstract Beryllium’s machining characteristics are similar to those of heat-treated cast aluminum and chilled cast iron. Like the other materials, it can be turned, milled, drilled, bored, sawed, cut, threaded, tapped, and trepanned with good results. This chapter explains how...

... largely by effects on the amount and shape of graphitic carbon present in the casting. For example, in low-alloy cast irons, depth of chill or the tendency of the iron to be white as-cast depends greatly on the carbon equivalent, the silicon in the composition, and the state of inoculation. The addition...

Casting producers use chill wedges to check the effectiveness of inoculation in order to prevent iron carbides (chilled edges) in the representative casting wall thickness. The width of the chilled section should be much less than that of the representative casting wall...
