The dataset is supplemented to the journal article Anand, A.: Cold spray additively manufactured pure iron for magnetic applications The dataset includes the fatigue crack growth rate data measured by the method described in Kovarik, O. :Differential compliance from time domain vibration waveform fit and its application to fatigue crack growth rate testing. It also contains the updated matlab fitting routine HS_CTU.m for the Hartmann-Schijve fit of the data as presented in Kovarik, O., Cizek, J., Klecka, J.: Fatigue Crack Growth Rate Description of RF-Plasma-Sprayed Refractory Metals and Alloys.
