Operating life of punch electrodes in the electric discharge sintering of copper-tin-abrasive composites

Outside Mainstream Electronic Databases: Review of Studies Conducted in the USSR and Post-Soviet Countries on Electric Current-Assisted Consolidation of Powder Materials

“…Raichenko et al [ 90 , 91 , 92 ], Svechkov et al [ 93 ], Baidenko et al [ 94 , 95 , 96 ] and Ryabinina et al [ 97 , 98 ] conducted a large number of experiments using this set-up.…”

“…The absence of Al shows that at the optimal ratio of Al and Fe, the volume fraction of the intermetallic can be increased up to 100%. Samples alloyed with Co were sintered under the same conditions [ 96 ]. After SPS in the materials containing Fe, Co and Al, several phases, such as FeAl, Fe 3 Al, FeAl 2 and FeCo increase the microstrains in the material [ 21 , 96 , 98 ] while γ-Fe and Co are responsible for an increased plasticity.…”

Sintering using an apparatus made by Thermal Technology LLC 10–3 (USA) [ 21 , 98 ] was conducted at the following parameters: the applied pressure was 60 MPa; the sintering temperature was 1200°C; the dwell time at the maximum temperature was 30 min; the residual pressure was 0.8 × 10 −2 –3 × 10 −2 Hg.…”
