Sieverts' law, in physical metallurgy and in chemistry, is a rule to predict the solubility of gases in metals. It is named after German chemist Adolf Sieverts (1874–1947). The law states that the solubility of a diatomic gas in metal is proportional to the square root of the partial pressure of the gas in thermodynamic … See more Sieverts' law can be readily rationalized by considering the reaction of dissolution of the gas in the metal, which involves dissociation of the molecule of the gas. For example, for nitrogen: N2 (molecular gas) … See more • Henry's law • Graham's law See more Webbehavior, i.e., they do not obey Sieverts law. The most striking feature of the deviation is the rapidly increasing exothermicity of the heat of solution as the hydrogen concentration approaches zero. To date this feature has been found to be common to all intermetallic-dilute hydrogen systems in which the two metal components consist of an ...
