Infants might have green stool as a result of: 1  Not finishing nursing entirely on one side, thus missing some of the high-fat content breast milk, which affects the digestion of the milk. 2  Protein hydrolysate formula (for babies with milk or soy allergy). 3  Lack of normal intestinal bacteria in breast-fed infants.
An alloy is a mixture of metals or a mixture of a metal and another element. Alloys are defined by a metallic bonding character.[1] An alloy may be a solid solution of metal elements (a single phase) or a mixture of metallic phases (two or more solutions). Intermetallic compounds are alloys with a defined stoichiometry and crystal structure.
That depends on the alloy of steel you are talking about. The term alloy is almost always used incorrectly these days, especially amongst bicyclists. They use the term to mean aluminum. What the term alloy really means is a mixture of metals, any kind of metals. Almost all metal used today is a mixture and therefore an alloy. Most steel has other metals added to tune its properties, like strength, corrosion resistance, or ease of fabrication.
