White JC; Traut DE
A method is described for determining the molten pool configuration in the melting of metals by (a) melting solid metal by suitable means to form a molten pool of metal in a crucible, (b) introducing hafnium metal seeds into the molten pool at suitable intervals as the molten pool cools and solidifies, (c) removing the ingot from the crucible and neutron activating it, and (d) determining the hafnium locations in the ingot by radiometric means.
