Post a brief description of the life transition or developmental issue you selected and your chosen theoretical orientation. Then, explain how you might modify the theory-based interventions of your chosen theoretical orientation to work effectively with client(s) experiencing the issue you selected. Finally, explain the significant aspects of the life transition or developmental issue that influence how you would modify the application of your chosen theoretical orientation.

Using the isothermal transformation diagram for an alloy steel (type 4340) specify the nature of the final microstructure (in terms of micro-constituents present and approximate percentages) of a small specimen that has been subjected to the following time-temperature treatments: In each case assume that the specimen begins at 760°C and that it has been held at this temperature long enough to have achieved a complete and homogeneous austenite structure. (a) (a) Rapidly cool to 400°C, hold for 10 seconds, and...
