Materials Science please show step by step To produce a layer of

To produce a layer of martensite on the surface of a steel part, the temperature of the layer must be decreased from the soaking temperature of 900C to 400C in 2s or less. If it is assumed that a quench instantaneously decreases the temperature of the surface from 900C to 25C, what thickness of martensite is produced? The thermal diffusivity of the steel is 1.2105m2/s
