It has proven possible to express the true stress-true strain behavior of dental casting alloys by means of a general equation with empirically determined constants. It was also found that the appropriate strain hardening equation for the precious alloys used in this investigation was an exponential function. Integration of the equations, using individually determined constants, made it possible to calculate the work necessary to plastically deform the alloys to a final true strain of 0.05 or any other realistic value. Comparisons of the ease of forming the alloys investigated here showed that this technique yields results similar to those encountered in clinical experience.
