1. These " nature prints " turned " metallography " into lithography. 2. Bakelite is also used in the mounting of metal samples in metallography . 3. Later, in 1937 he became the first Metallography Professor at the Institute. 4. This discovery is the beginning of scientific metallography . 5. In metallography , an alloy of interest is ground flat and polished to a mirror finish. 6. In 1916, he published " The Metallography of Steel and Cast Iron ". 7. Metallurgists study the microscopic and macroscopic properties using metallography , a technique invented by Henry Clifton Sorby. 8. This is exactly the same method as that used by materials scientists in preparing polished samples for metallography . 9. The development of metallography was a continuous struggle to find better and easier methods to prepare metal surfaces for microstructure observation. 10. H . Struers Chemiske Laboratorium is still active within metallography but is today just called " Struers A / S ".
