Description

Charpy V-notched impact tests were conducted on Fe-29 Mn-8 Al-1.5 Si-1 C austenitic stainless steel over a range of temperatures (293 K to 77 K) on solution treated and aged specimens. The results of this study demonstrate that aging promotes multiple crack initiation, reduces the energy absorbed by the material and lowers the peak load sustained by the material. These observations may be rationalized by the formation of a brittle β-Mn phase upon aging. The room temperature impact properties of the solution treated specimens are comparable with those of conventional Fe-Cr-Ni stainless steels. (orig.)
