Consider the diffusion of some hypothetical metal Y into another hypothetical metal Z at 950C; after 10 h the concentration at the 0.5 mm position (in metal Z) is 2.0 wt% Y. At what position will the concentration also be 2.0 wt% Y after a 17.5-h heat treatment again at 950C? Assume preexponential and activation energy values of 4.3 104 m2 /s and 180,000 J/mol, respectively, for this diffusion system.
%ECE 102 assignment 6 problem solving %Mausam Rayamajhi PROBLEM STATEMENT To find whether the velocity of at the second point increases, decreases or remains the same as the first point INPUT AND OUTPUT Input = A1 and A2 output = V2 1. Enter the Area of the first point, A1 and area of the second point, A2 2. Initialize V1 = 3 3. Calculate V2 = (A1*V1)/A2; 4. If V2 > V1, print increased 5. Else if V2 = V1, print equal 6. else V2 < V1, print decreased 7. end Test If A1 = 1 and A2 = 3 then V2 would be 1 which will give an output, decreased If A1 = 9 and A2 = 3 then V2 would be 9 which will be an output, increased If A1 = 6 and A2 = 6 the V2 would be 3 which will be an output, equa
