2 a) It is given that a carburizing heat treatment of 10-hour duration of a steel alloy will raise the carbon content to 0.45 wt% at a point 2.5 mm away from the surface. Compute the time required to get the same concentration at a 5.0-mm position from the surface at the same carburizing temperature for an identical steel alloy (Hint: The diffusion coefficient will be a constant for two identical materials at a given temperature). b) What is the...

HEAT TREATMENT OF STEELS EXPERIMENT 6 EXPERIMENT 6 HEAT TREATMENT OF STEELS THEORY The Effect of Cooling Rate One of the most convenient methods for controlling the properties of a given steel, i.e., a steel whose composition is already fixed, consists of austenizing the steel and ten cooling to room temperature at some predetermined rate. A variation of cooling rates...

(might be 1 or 2, MCQ questions were having images given with them, which we couldn't insert, so ignore those questions if you cannot answer, sorry for inconveinience created, i tried to delete them but might be couldn't done all) 3) Single phase induction motors work because: a) The oscillating magnetic field can induce starting torque in a rotor. b) The oscillating magnetic field can induce running torque in a rotor. c) A capacitance or inductance can create the phase...
