Interpretación de los valores de microdureza de la recta de Gahm. Aplicación del método al estudio de la dureza de la hematites y de la cobaltina

Abstract

The description of how to obtain the experimental data of the hardness at microscopical scale in hematites and cobal- tirie and of the respective equipments used is given. The graphics of the data obtained are exposed according to Gahm, to obtain the best straight line. The conclusions and recomtnendations on doing the research work on the hardness of the minerals, are stablished.
