Sentence examples for behaviour at intermediate temperatures from inspiring English sources
These results confirm that water-assisted, thermally activated quartz deformation is a key process in the velocity-weakening behaviour at intermediate temperatures in wet illite/quartz gouges and support the existing microphysical model.
Pesting was eliminated in the alloy Nb 24Ti 18Si 5Al 5Cr 2Mo 5Hf 5Sn at 800 °C, indicating that the addition of Sn plays an important role in controlling the pest oxidation behaviour at intermediate temperatures.
In the terminology of Rate and State Friction (RSF; Dieterich 1978, 1979; Ruina 1983), both gouges showed stable, 'velocity-strengthening' (or near-neutral) behaviour at low temperatures (Regime 1), potentially unstable, 'velocity-weakening' at intermediate temperatures (Regime 2) and velocity-strengthening at the highest temperatures investigated (Regime 3; Den Hartog et al. 2012a, 2013).
Both the wet illite/quartz and wet illite gouges showed three regimes of velocity dependence, characterised by more positive (a-b) values at low (<250°C) and high (>400°C) temperatures than at intermediate temperatures (350°C), although our data suggest that the three-regime behaviour is muted in the wet illite gouge relative to the wet mixtures (cf. Figure 2a,b).
Solutions at intermediate temperatures form simple sulfides and sulfosalts for the most part, and those at higher temperatures form sulfides and oxides.
At intermediate temperatures, dynamic strain ageing effects occur.
At intermediate temperatures, the formation of hydrocarbon and alcohol intermediates slows the oxidation process relative to the low temperatures.
Compared to H2O diffusion in rhyolite, diffusivity in dacite is lower at intermediate temperatures but higher at superliquidus temperatures.
