Precipitation Hardening - an overview ScienceDirect Topics

Precipitation hardening,another mechanism of second-phase strengthening in alloys,occurs when the solid solubility decreases with decreasing temperature; this allows the solutionizing of as-cast second phases to be re-precipitated in a controlled fashion.When rapidly cooled from a homogeneous solid solution at high temperature,the alloy produces an unstable supersaturated solid solution which,Precipitation Hardening - an overview ScienceDirect TopicsPrecipitation-hardening,characterized by the nucleation,growth and coarsening of second phase particles from a metastable supersaturated solid solution,is responsible for increasing the strength and hardness of a large number of alloys.Precipitation Hardening Alloy - ScienceDirectPrecipitation hardening metal alloys have their alloying elements trapped in solution during quenching,resulting in a soft material.Ageing a solutionised metal will allow the alloying elements to diffuse through the microstructure and form intermetallic particles,which fall out of solution and increase the strength of the alloy.
