Metallographic Quality Studies of Thorium Metal
- New Brunswick Laboratory (NBL), New Brunswick, NJ (United States)
Thorium metal, as cast, arc-melted ingots and rolled wrought metal has been examined microscopically for inclusion and stringer concentration. Tentative rating methods for metal quality have been proposed based on the number and diameter of the inclusion clusters in cast metal. For the wrought material the quality ratings follow the method as proposed for uranium, namely, the total length of the stringers found over a definite area. Thirty-one photomicrographs of varied inclusion shapes and concentrations are shown for the purpose of acquainting the reader with typical inclusions found in thorium metal.
