Automatic Impact Testing from Room Temperature to −236 C

Source

Using liquid nitrogen and liquid helium as coolants, Charpy V-notch impact tests were conducted from room temperature to −236 C in an automatic device, which houses within a vacuum a complete impact machine and storage space for 105 specimens. Comparison impact tests of AISI 4340 steel conducted on both a conventional and the low-temperature impact machine to −195.8 C show that the device is a useful and accurate impact tool.
