... can promote wear. The increased use of a type of cast iron known as compacted graphite iron (CGI) often results from this conundrum, because it can offer increased strength, when compared to aluminum alloys, and reduced weight, when compared to other cast irons. Although denser than aluminum...

... be considered similar in their effect on ductility to the graphite flakes in gray cast iron. The cause of the embrittlement, then, is not so much the absorption of hydrogen as the formation of the crack-like voids. Evidence will be given later to support the postulate that these voids are formed because...

This Omega model enables the entire creep curve (when the creep behavior is predominantly tertiary creep) to be used in life assessment, instead of merely using the time to rupture or minimum creep rate. It has been used to characterize material creep deformation in a compact form, to fit data collected...

The movement was controlled by a long lever system. Because the resultant debris on steel specimens was the red iron oxide α-Fe 2 O 3 , which had risen from...

Energy-dispersive spectrometry (EDS) scans of an oxidized area of the fracture revealed traces of sulfur and chlorine, probably from the dye penetrant, and the iron, chromium, and nickel normally present.

Still further heating may cause final reversion of the iron carbide to graphite, which may result in loss of impact and ductility and reduction of tensile strength properties. Figure 5 shows spheroidization...
