In situ XRD measurements were performed at ESRF, Grenoble, France (ID11) during quenching of a ball bearing steel AISI 52100 (100Cr6) with varying carbon content in solution as discussed by the authors.Abstract:
In situ XRD measurements were performed at ESRF, Grenoble, France (ID11) during quenching of a ball bearing steel AISI 52100 (100Cr6) with varying carbon content in solution. The evolution of austenite lattice parameter during cooling is nearly linear until Ms is reached and then, a divergent behavior can be observed. Assuming that the extrapolation of the linear range to room temperature gives the stress-free lattice spacing, an increasing compressive hydrostatic stress state is resulting. A strong effect of the carbon content was found. These results were confirmed by theoretical calculations based on data from the literature.read more

Calibration and correction of spatial distortions in 2D detector systems
TL;DR: Bi-cubic splines are proposed as suitable interpolating functions for defining approximate spatial distortion functions in 2D detector systems, allowing both adequate flexibility to describe arbitrary distortions and efficient calculation for the correction of data.
