Materials Engineering Question

Suggest the optimal heat treatment and condition for 0.45 wt.% steel required, to produce what you consider to be the best combination of properties for a “Chef’s Knife”. Explain your answer and use any literature required to justify it.

Expert Solution

Heat treatment is used for improving properties of a material. A chef's knife must retain its hardness and sharpness corossion resistance through out the service period.

Thus can be hand forged or stamped. In hand forging knife is heated to an elevated temperature and made into shape by a skilled mannual labour. It is then ground.

In stamping a knife is cut from the cold rolled stampings. It is then tempered. Tempering means heating of knife between 300 to 500 degrees Celsius for a prolonged time. If annealing is done instead of tempering, hardness of knife deacease drastically. A plain carbon steel retain its sharpness than a stainless steel knife.

As part of a heat treatment process, cylindrical, 304 stainless steel rods of 100-mm diameter are cooled from an initial temperature of 500ºC by suspending them in an oil bath at 25ºC. If a convection coefficient of 500 W/m2·K is maintained by circulation of the oil, how long does it take for the centerline of a rod to reach a temperature of 52ºC, at which point it is withdrawn from the bath? If 9 rods of length 1 m are...

Introduction to Engineering Materials Question: A beam of light hits a 2.48cm thick silicate glass plate at an angle of 74 degrees (as measured from the normal to the surface of the glass). If the coefficient of linear absorption is 0.027 cm-1 and the index of refraction is 1.488, what fraction of light is passed through the plate. The answer should have three decimals of accuracy.
