Carbon Analysis in Steels by FE-EPMA: A Challenge or Contradiction?

“…To improve the spatial resolution a method is chosen which combines non-linear optimization with Monte-Carlo simulations to solve for the composition of a small structure inside a matrix using experimental kratios and predicted k-ratios [3]. From an initial guess, an iterative method uses search directions, retrieved from the Jacobian matrix approximated by finite differences, to find a local minimum.…”
