Abstract
A description is given for an apparatus and technique used to zone melt reactive, high-melting-point metals by the floating zone method. The use of radioactive tracers to determine the redistribution of solute during zone melting is discussed and results are shown for P32 in iron, Au198 in titanium and zirconium, and Zn65 in titanium. Some tensile results on iron at liquid nitrogen and liquid helium temperatures are given which indicate that the removal of trace impurities markedly increase the low temperature ductility of iron.
