For two hypotetical materials which have limitless solubility for both in the “liquid” and “solid” states in each other, the following data are listed. Melting Temperatures of material A and B are Tm,A and Tm,B respectively, Liquidus and Solidus curves are circular arcs.
a- Draw the related “Phase Diagram” of Material A and Material B showing the data given and calculated.
b- Calculate/Determine the compositions of phases at T2 , explain the procedure.
c- Calculate/Determine the “percentages” of “phases” of Alloy,2 at T2 , explain the procedure.
Given:
-Tm,A, Celcius =530
-Tm,B, Celcius =830
-T1, Celcius =630
-B percentage of Liquid phase at
T1 =35
-B percentage of Solid phase
at T1 =80
-B percentage of Alloy 2. =60
-T2, Celcius =680
-B percentage of Liquid phase of
Alloy 2 at T2 = to be calculated
-B percentage of Solid phase of
Alloy 2 at T2 = to be calculated
Using the Mg-Pb phase diagram below, if you start at point A and cool down very slowly to room temperature (point D), sketch the microstructure associated with each letter, determine what phases are present at each letter, determine the compositions for each phase, and determine the weight in each phase. The Mg-Pb mixture has 20 wt. % Pb in it. You start with 100 kg.
If the initial composition of the carbon steel is c0=0.3 wt%, calculate the carbon concentration (in wt%) at a distance 0.2mm from the surface of the component after 1 hour of decarburization.
