Electrical Conductivity in Aluminum: Possible Alternative to Thermal Analysis

In recent years, thermal analysis has become popular as a method to assess the grain size and degree of eutectic modification in aluminum-silicon casting alloys. In applications that do not require information about grain size, measurements of electrical conductivity can provide the same degree of control of the eutectic structure at substantially reduced costs.

Surprisingly overlooked as a testing procedure, the method is so simple that a foundryman can purchase a standard piece of off-the-shelf ...
