114 words
THE METHOD OF DISPLAYING THE CRYSTAL GRAIN ORIENTATION OF THE SURFACE OF A SAMPLE MATERIAL HAVING A CRYSTAL GRAIN ORIENTATION COMPRISING, PLACING SAID MATERIAL IN A SUBSTANTIALLY EVACUATED ENVIRONMENT SO THAT THE SURFACE THEREOF FACES IN A CERTAIN DIRECTION, POSITIONING A DISPLAY PLATE TO SUBSTANTIALLY FACE SAID SURFACE, CONDUCTING RADIO FREQUENCY ENERGY THROUGH SAID ENVIRONMENT AT A POTENTIAL HIGHER THAN SAID SURFACE CAUSING SPUTTERING OF SAID SURFACE AND EJECT ATOMS THEREFROM IN AT LEAST ONE KPATH DETERMINED BY THE CRYSTAL STRUCTURE OF SAID MATERIAL, OBTAINING A DISPLAY OF THE PATH OF ATOMS EJECTED FROM SAID SURFACE AND COMPARING SAID DISPLAY WITH A STANDARD TEST PATTERN TO DETERMINE THE PROPERTIES OF THE CRYSTAL GRAIN ORIENTATION.
