Assume there was an error in the prior heat treatment of an alloy that resulted in the formation of 100% bainiteinstead of pearlite. For the same alloy, briefly describe a simple heat treatment procedure for the formation of 100%pearlite. Your answer should include the temperature(s) and time(s) involved.

If you chip a tooth, most likely you will go to the dentist to have the missing material filled in. currently the material used to fill in teeth is a polymer that is flexible when put in, yet is hardened to the strength of a tooth after irradiation with blue light at a wavelength of 461 nm. what is the energy in joules for a photon of light at this wavelength?
