Abstract
Impact testing at temperatures down to 77 K is routinely accomplished according to ASTM specifications. The specimen is transferred in open air from a liquid bath to the test machine anvil and the pendulum is released within 5 sec. However, this method is impractical at lower temperatures since the low heat capacity of the metal leads to a rapid increase in specimen temperature during transfer.
