Proeutectoid Phase

Consider 1.0 kg of austenite containing 1.15 wt% C, cooled to below 727 degrees Celcius (1341 degrees Farenheit). a) What is the proeutectoid phase? b) How many kilograms each of total ferrite and cementite form? c) How many kilograms each of pearlite and the proeutectoid phase form? d) Schematically sketch and label the resulting microstructure.

Phase Transformation Diagrams

Briefly describe exactly how phase transformation diagrams (eutectoid, isothermal) are constructed. Thanks.

Method of Joints; Tension or Compression

(a) Find the reactions A and D {see attachment for diagram} (b) Use the Method of Joints to determine the force in each member. Indicate the magnitude of the force whether the member is in tension or compression.

Method of sections

a. Find the reactions at A & G b. Use the _METHOD OF SECTIONS_to find the forces in members IJ, EJ, and DE. Indicate also whether in tension or compression

Defluorination & adhesion properties

Using ion bombardment-If Teflon is deflorinated to increase it's adhesion properties, then what would the changes in surface characteristics be? I'm trying to use this information so that I can decide what techniques I'd use to analyze the surface to see if the method worked. So basically, I don't understand what removing flourine by ion bombardment does to the surface properties/condfiguration. Please help!
