A system for more rapidly determining the strength and stiffness of polyphase alloys is presented that is based on a digital representation of the material structure. Working in concert with the representation are a number of digital tools and probes that are analogues of testing equipment and instrumentation of traditional laboratory methods. These are combined with nontraditional mechanical testing methods to complete the system. An example of an Fe-Cu system is used to illustrate the methodology.
