In contrast to their silent cracking behavior at room temperature the austenitic stainless steels are highly active acoustically during deformation and fracture at 4 K. Acoustic emission is promoted by low temperature strengthening and by discontinuous plastic flow in ductile alloys near absolute zero. The prospects are consequently good for acoustic emission monitoring as a tool in studying austenitic steels at cryogenic temperatures. This paper illustrates some potential applications in mechanical property determinations and presents test results acquired for two steels, Fe-18Cr-3Ni-13Mn, AISI 310S WM, and a shielded metal arc weld of AISI 310S BM, submerged in liquid helium. A monitoring apparatus is also described.
