What is cryogenic temperature and Cryogenics?

A Temperature below -150°C or -238°F or around 123 K, in which a number of physical phenomena start to change rapidly from the room temperature characteristics. And Cryogenics is the science which deals with the study of achieving cryogenic temperatures and their effect on materials.

What is Hydrogen embrittlement ?

Hydrogen embrittlement is an undesirable process resulting loss of ductility of metal, decrease of the toughness and reduction of load-bearing capability occurs due to the absorption of hydrogen atoms by the metal. So that there is crack formation in metal component and fracture at lower stresses conditions. There are mainly two types of Hydrogen embrittlement. The first one is internal hydrogen embrittlement, It occurs when the hydrogen dissolved in molten metal which becomes supersaturated with hydrogen immediately after solidification. And the second type is environmental hydrogen embrittlement, which results from by hydrogen absorption by the solid metal. This condition can occur during high-temperature thermal treatment & during electroplating, during corrosion reactions, during cathodic protection, operating hydrogen in high-pressure conditions etc.

What is Solid solubility?

Solid solubility is defined as the amount of solute that is soluble in solvent. Solid solubility of any alloy depends upon atomic size, valencies, and crystal structure and electronegativity parameters. Solid solubility limits is decided on the basis of the Hume–Rothery rules for solid solution formation. Solid Solubility limit is the limit to which one metal is capable to form solid solutions with respect to other metal. In case of solid dissolved in liquid water, the solid solubility increases because of increase average kinetic energy of the solute molecules with increment of temperature.
