Consider a metal with an FCC crystal structure. The interplanar
spacing is known to be (2.0000x10^-1) nm. If the first-order angle
of diffraction (2*theta) is found to be (4.50x10^1) ° for the (311)
set of planes in this metal, what wavelength of monochromatic
x-radiation (in nm) must have been used for the diffraction? Use
scientific notation with 3 significant figures (X.YZ x 10^n). Note
that Avenue automatically enters x10, so you only need to enter
X.YZ and n.
A single crystal of a metal that has the FCC crystal structure
is oriented such that a tensile stress is applied parallel to the
[110] direction. The critical resolved shear stress for this
material is 1.75 MPa.
1) Calculate the magnitude of applied stress necessary to cause
slip to occur on the (111) plane in the (1-10) direction.
2) Calculate the magnitude of applied stress necessary to cause
slip to occur on the (111) plane in the (10-1)direction.
3) Which...
