Özet

Fe powders mixed with 2% Cu by weight were compacted with 600 MPa to form 3-point bending samples having dimensions of 10×10×55 mm. Compacted powders were sintered by using medium-low frequency (30 kHz, 12kW) induction energy in conveyor system. Sintering process was completed in several sintering durations from 400 to 1300 seconds at 1120°C under atmospheric environment (open air). Micro structural and mechanical properties of sintered samples were investigated. Maximum stress for 3-point bending was achieved at 1000 seconds of sintering duration at 1120 °C. The mechanical properties of induction sintered samples were compared with conventionally sintered samples at 1120 °C for 30 minutes of sintering duration under argon atmosphere. The maximum stress values for induction sintered sample were nearly similar to conventionally sintered samples.
