Small punch tensile/fracture test data for Gr. 91 material at -170 °C and a displacement rate of .5 mm/s

In the framework of its institutional project on Gen IV nuclear reactors, the JRC-IET performs pre-normative materials qualification research within the work package PreMaQ.
The activities focus on evaluation methods like ultrasonic fatigue, neutron diffraction, thermoelectric power measurements, x-ray tomography, small punch creep and fracture tests, and nano-indentation with the aim to establish or prepare international standards.
The current data set belongs to a small punch tensile/fracture mechanics test on the ferritic/martensitic steel Grade 91.
