IMPACT STRENGHT
ABSTRACT
Impact energies of metal injection molded (MIM)
steels are investigated. A notched Charpy test specimen
for the MIM process is proposed. Two alloys (410
stainless steel and low carbon Fe-7% Ni) are processed
and tested for energy absorbed in fracturing the
specimens. These values are compared to wrought alloys.
The results demonstrate that MIM alloys can be
successfully tested for impact strength using standard
notched specimen, with results comparable to similar
wrought alloys.
