Dislocation density measurement in cold rolled metals using XRD and TEM
Which of the following best describes the magnitude of the Burgers vector, b, in most metals?
In a TEM-based dislocation density measurement, if the sample thickness (t) is doubled while the dislocation line length (Ld) and imaged area (A) remain the same, the calculated dislocation density will:
For XRD-based methods, peak broadening in cold-rolled metals can result from dislocations and which other major factor?
During TEM imaging, dislocations appear as dark lines primarily because they:
The formula ρ = Ld / (A x t) (or ρ = N / (A x t) if counting discrete segments) is used to calculate:
Which parameter below is not directly required in calculating dislocation density using a single XRD peak-broadening method?
