Web12 sep. 2024 · When the gas expands by d V, the change in its temperature is d T. The work done by the gas in the expansion is d W = p d V; d Q = 0 because the cylinder is insulated; and the change in the internal energy of the gas is d E i n t = C V n d T. Therefore, from the first law, C V n d T = 0 − p d V = − p d V so d T = − p d V C V n. WebThe thermal expansion coefficients, TECs, of the MAX phases fall in the narrow range of 8 to 10×10 −6 K −1 (Table 5).A correlation exists between the TECs of the ternaries and the corresponding MX binaries (Barsoum 2000, El-Raghy et al. 2000).For example, the TECs of the Hf-containing MAX phases are lower than those containing Ti, which in turn are …
