It describes the intermediate phases that are formed during solidification between the two extremes of substitutional solid solution on the one hand and intermetallic compound on the other. The chapter concludes with a section on strain aging in low-carbon steels that allows the interstitial...

Some intermediate phases can accurately be called intermetallic compounds, when, like Mg 2 Pb, they have a fixed simple ratio of the two kinds of atoms. However, many intermediate phases that exist over a range...

... residue was formed, which was thought to be a product of corrosion. Actually, what was happening was the formation of an intermetallic compound, an aluminum-gold precipitate (Al 2 Au) that is purple in color and very brittle. Millions of actual and opportunity dollars were lost in identifying the problem...

... a solid solution, is tough and ductile, so α-phase alloys can be cold worked. However, the δ phase is an intermetallic compound containing the composition Cu 31 Sn 8 , which is a hard, brittle phase that makes the α + δ bronzes rather brittle. Therefore, the δ phase must be absent for alloys that require...

Aluminum alloys are never hard, but anodize treatments can produce a thick and dense coating of aluminum oxide when a tribosystem needs a hard surface. These are valuable attributes, and this list is probably longer than...
