What is the composition of the phase(s) present at 1200C for 25 wt% Ni alloy? Refer to the Cu-Ni phase diagram below.

Relative to the direction of an applied shear stress, the direction of motion of an edge dislocation’s line is

Which phase(s) are present and what is the composition of the phase(s) at point H?

What is the maximum solubility of Pb in Sn?

Consider 2.5 kg of austenite containing 0.65 wt% C, cooled to below 727˚C.  What is the proeutectoid phase?

Consider a metal single crystal oriented such that the normal to the slip plane and the slip direction are at angles of 60° and 35°, respectively, with the tensile axis. If the critical resolved shear stress is 7 MPa, will an applied stress of 13 MPa cause the single crystal to yield? If not, what stress will be necessary?

This single phase of the iron-carbon phase diagram can have up to 2.14 wt% carbon

For a particular crystal structure, the slip plane is most likely to be?
