Применение метода цветового картирования в металлографических исследованиях образцов после динамического нагружения

A method of constructing 3D color maps that can be used to represent the results of metallographic study of the structure and properties of the samples subjected to shock-wave loading is considered. The method is used to measure damage, hardness and micro-hardness of metallographic specimens of two spherical shells made of uranium alloys subjected to symmetrical explosive compression. Structural changes and damage of the shell material attributed to shock-wave processes are localized in the bulk alternating zones. Analysis of the damage consists in assessing the size and shape of the microcracks in cross section and determation of their location. Distributed measurements of the hardness and microhardness are carried out over the entire cross section in study. The data array (up to 50 GB) of the measured values is too large for “traditional” methods of analysis, whereas the method of color mapping demonstrated the capability of processing data on hundreds of thousands cracks and several thousands of tests for hardness- and micro-hardness still being rather efficient.
