This is because the reflected beam will then have a path difference with the incident beam of 0.5λ, thus leading to destructive interference. An increase in carbon or manganeses makes deeper hardening steel and less makes it slightly softer and not as deep hardening. After some discussion, it was accepted in 1925 that the colours of thin films of oxide are interference effects (U. R. Evans, Proceedings of the Royal Society of London. Most farrier tools, like pritchels and forepunches, are made from high carbon steel and can be damaged at this temperature. 910.
