Austenitic stainless steels are the most widely applied types of stainless steels, due to their good weldability and high corrosion resistance. A number of engineering diagrams exist for the purpose of providing insight into the behavior of these steels. Examples of these diagrams are constitution diagrams (aka Schaeffler Diagrams) which are used to approximate the solidification path of the alloy and the amount of retained ferrite in the solidified matrix. Other diagrams are the Suutala diagram, which approximates cracking susceptibility, and microstructural maps, which predict the solidification path by varying a processing parameter, such as cooling rate. By combining these diagrams, a much more concrete conclusion can be made as to the behavior of a particular steel. This approach could be used to determine differences in behaviors between two different compositions. The developed diagram would be intended for use with rapid solidification phenomena as observed in the selective laser melting process.
