Anthropic Principle Observed in the Material Properties of Fe

Abstract

The melting temperature of Fe is 1808K (1535oC). If it were higher than that, the ancient people could neither produce iron products, nor achieve the civilization. When the melting temperature of Fe is observed on the periodic table, it seems that the melting temperature is lowered intentionally and unnaturally. It can be suspected to be a sort of the anthropic principle. Fe belongs to the gulf elements, when the melting temperature is plotted on the TC-YM diagram. The gulf elements show the moderate melting temperatures totally. Moreover, Fe is also located on the quadrant of the large abundance on the TC-YM diagram. Fe is also located at the position in the TC-YM diagram, which shows relatively small ionization tendency, which means easy smelting. Fe is also located at the position between the straight line of refractory metals of bcc structure and Ni of fcc structure, which leads to the crystal structure of Fe to be bcc structure at lower temperature and fcc structure at high temperature. 

These advantages in the properties of Fe come from its exquisite position of Fe on the TC-YM diagram. These can be thought an anthropic principle in Fe.
