Summary

Effect of gelatin hardening on the results of hydrogen microprint technique was studied in order to establish the technique to visualize hydrogen behavior in metals in high resolution and with high accuracy. A pre-treatment of a gelatin-base AgBr emulsion with formalin is confirmed to be an effective method for hindering redistribution of silver particles in hydrogen microprint technique. This process enables reproductive, quantitative and detailed observation of fine silver particles, and provides an original power of resolution which depends on a diameter of a silver bromide crystal in the emulsion used.
