Metastable phase definition

Web9 jul. 2024 · A metastable state of an isomer is defined as an excited state that exists for greater than 10-6 seconds. In chemical notation, metastable species are identified by the letter 'm'. Typically, excited nuclei will instantaneously decay to a more stable energy state (within 10-15 seconds), emitting radiation in the process.. However, some excited nuclei … Webmetastable sample is held isothermally at a temperature where austenite cannot form. The changes during the tempering of martensite can be categorised into stages. During the first stage, excess carbon in solid solution segregates …
