Benjamin Lewis Averbach, S. Andrew Kulin and Morris Cohen pose around testing equipment in a laboratory.

Original Caption: "In the Metallurgy Department Laboratories at the Massachusetts Institute of Technology, Dr. Benjamin L. Averbach (left), S. Andrew Kulin, and Dr. Morris Cohen discuss current research activities in the mechanism of how steel hardens. Studies by these metallurgists have refuted many ideas of low-temperature behavior showing that steel can harden at the extremely low temperatures of liquid helium. The equipment shown in the picture is used in studies of steel hardening under tension at more moderate degrees of cold."
