<p>METHOD AND APPARATUS FOR PREDICTING METALLOGRAPHIC STRUCTURE A metallographic structure such as nodularity in castings to be made from molten metal is predicted by causing one part of the sample to rapidly solidify at a first rate and a second part of the sample to solidify at a slower rate. The temperature of at least said one part of the sample is measured during solidification. After solidification of the one part of the sample, the heat conductivity of the sample is used to predict the metallographic structure of the sample.</p> |
