Pre oxidation does not affect behavior at intermediate temperatures but at 700 °C causes a significant reduction in friction coefficient and wear.
In recent years, nano-binders (mainly colloidal suspensions) have been proposed as alternative materials for applications that require CaO-free refractory lining or improved mechanical behavior at intermediate temperatures (700 °C< T < 1200 °C).
However, complex behavior of velocity dependence of clay minerals has been reported at elevated temperatures, in which velocity-weakening behavior is found at intermediate temperatures for illite-rich gouges, whereas velocity-strengthening behavior occurs predominantly at lower and higher temperatures (den Hartog et al. 2012).
At intermediate temperature, partially sintered and non-spherical NPs are formed.
They are also observed at intermediate temperature (b), although in smaller quantity.
It has been devoted to thermal measurements of nanomagnetic systems at intermediate temperature (20 300 K).
At intermediate temperature and pressure, the spectrum of 1 displays two bands.
Taking into account the anomalously intense oxidation of Ti3AlC2-based material at 500 °C and especially at 600 °C [8], the investigation of oxidation behavior of these materials at intermediate temperatures has a great importance.
In spite of thorough research of oxidation behavior of Ti3AlC2-based materials at high temperature, only a few results obtained at intermediate temperatures have been reported [8, 9].
Although the ductility and toughness of these composites at ambient temperatures is improved by the B doping, those of Ni3Al composites drastically decrease at intermediate temperatures due to dynamic oxygen embrittlement, deterioration of grain boundary cohesion and unique behavior of dislocations.
