The organisation of the city appears to have differed from that of other Maya sites and appears to have been geared towards a specialised coastal trade in salt.
Steel is a solid solution, a subtype of chemical mixtures that involve two or more molecules in a solid state that combine to form a single substance while retaining their individual identities. The component metals making up steel are not chemically bonded together. Continue Reading.
Phosphorus is one of the most potent solid solution strengtheners of ferrite. Hence, small additions of phosphorus are used to inexpensively increase the strength of low carbon sheet steel. Figure 1 compares the change in lower yield strength of carbon steel as a function of alloy addition for several common elements.mong the elements considered, only carbon and nitrogen produce a greater strengthening effect than phosphorus. This is related to the fact that phosphorus enters the crystal lattice as a substitution solute, whereas carbon and nitrogen are interstitial solutes in ferrite. Nevertheless, the addition of only 0.1 wt.
