Consider 2.5 kg of austentie containing 0.65 wt% °C, cooled to below 727°C a) What is the pro-eutectoid phase? b) How many kg each form of ferrite and cementite? c) How many kg each form of pearlite and the pro-eutectoid phase?

The plot to the right shows the 1-D steady-state solution to the Pennes bioheat equation with T = 37°C at x = 0 (body core) and T = 43°C at x = 0.01 (body surface). The thermal conductivity is 0.5 W m-l °C-'. This scenario describes some surface tissue thermal conductivity (WI(m°C)) 0.5 blood perfusion rate (1/5) T("C) 43 heating (e.g., laser).
