Strength of alpha quartz: New results from high pressure in-situ deformation experiments

We present a suite of 13 uniaxial deformation experiments on Arkansas novaculite conducted in D-DIA apparati, located at the Advanced Photon Source (6BMB) and the National Synchrotron Light Source (X17B2).  The experiments were monitored with in-situ synchrotron x-rays and conducted at temperatures ranging from 25 °C to 1199 °C, pressures between 1.39 GPa and 3.1 GPa, and strain rates between 1 × 10 -5 s -1 and 1 × 10 -6 s -1. Macroscopic sample strain ranges from 3% to 24%. d-spacings from the (101), (110), (200), (201), and (112) lattice planes produce lattice strain up to ~5%.  The files here include diffraction data, radiographic images, and instrument logs tracking furnace parameters, oil pressures in the main ram and DDIA rams, and a variety of positional sensors for the DDIA apparatus.  Combined with information published in the associated manuscript, the diffraction data may be reanalyzed as part of future studies examining the diffraction behavior of quartz being deformed at high temperature and pressure.
