Dilatometry data for high-field flash sintering of oxide ceramics

Provided are raw datasets of the dilatometry taken during the high-field flash sintering tests on non-sintered and (approximately) fully pre-sintered samples. Curves are provided in GERMAN .csv format (Semicolon-separated, comma as decimal separator). The dilatometery data was used to determine the onset temperatures of the flash event based on the thermal expansion/fracturing behavior. ATTENTION: The dilatometry curves of this dataset must not be interpreted as shrinkage due to flash sintering. In nearly all cases it represents the fracturing of the samples due to the rapid runaway at the high fields. The curves were used to verify that a proper thermal runaway, signified by a small thermal expansion right before the flash event, takes place for each measurement. This dataset belongs to a manuscript currently under review in Acta Materialia. Title of the manuscript is "Flash sintering in oxides: the Debye temperature is not the limit" by Daniil Lewin and Doru C. Lupascu.
