Please contact the submission author. In its pure form, iron is soft and generally not useful as an engineering material; the principal method of strengthening it and converting it into steel is by adding small amounts of carbon. This difference in boiling points may be attributed to a difference in, In a molecule in which the central atom exhibits sp3d2 hybrid orbitals, the electron pairs are directed toward the corners of, Is used to explain why the boiling point of HF is greater than the boiling point of HBr, The SbCl5 molecule has trigonal bipyramid structure. From this point down, the iron crystals are all in an austenitici.e., fccarrangement and contain all of the carbon in solid solution. The martensite is formed by rapid cooling (quenching) of austenite which traps carbon atoms that do not have time to diffuse out of the crystal structure. Steel is an interstitial alloy made from Carbon and iron atoms. He applied a current to the wire which made it red hot.
