compression-dilatometer-analysis-ZrNb: a python script for analysing Zr-2.5Nb compression dilatometer data

A python script for analysing compression dilatometer data, allowing the user to plot the stress-strain data and for generating 'processing maps' of a material. The script was used to analyse data recorded in uniaxial compression for a Zr-2.5Nb alloy deformed at temperatures of 650C, 675C, 700C, 725C, 750C, 775C, 800C, 825C and 850C, at strain rates of 10-2.5, 10-2, 10-1.5, 10-1, 10-0.5 and 1 s-1, to 50% height reduction, using TA Instruments DIL 805 A/D/T Quenching and Deformation Dilatometer.

The data for this experiment can be downloaded from;
