The precipitation-hardening process involves three basic steps 1) Solution Treatment,or Solutionizing,is the first step in the precipitation-hardening process where the alloy is heated above the solvus temperature and soaked there until a homogeneous solid solution () is produced.The precipitates are dissolved in this step and any segregation present in the original alloy is reduced.Some results are removed in response to a notice of local law requirement.For more information,please see here.Phase transformations and phase diagrams [SubsTech]Jun 26,2017 Precipitation behavior and phase transformation of hyper#0183;Eutectic phase diagram describes behavior of the alloys,two components of which are completely soluble in liquid state and entirely insoluble in solid state..This diagram has two liquidus curves,starting from the freezing points of the two metals and intersecting in a minimum point eutectic point.Consider solidification of an alloy with concentration C.
