A transmission microscope study of uranium

  • J. Silcox


One of the advances made in metal physics during recent years has been the application of electron transmission microscopy to the study of thin films of metals. In this manner, dislocations and other microstructures (1, 2) have been revealed and studied directly. At Cambridge, work has been concentrated on producing thin films by electro-polishing. This technique permits direct examination of the dislocation arrangement as they exist in the bulk material although the subsequent movement is thought to be characteristic of thin films Such studies have so far been made on aluminium, austenitic stainless steel, alpha-brass, copper, nickel, magnesium, iron, cobalt and gold (3, 4). With the exception of gold, these metals are all of relatively low atomic number. The experiments have now been extended to uranium, a metal of high atomic number with a view to studying the dislocation arrangements and irradiation effects. This paper records some preliminary results on alpha-uranium, the phase which is stable up to 668° C.
