“…In the literature [28,29], in studies on determining the effect of Ni addition on the mechanical properties of steels, it is seen that the high Ni content in post-quenching processes decreases the strength as it causes residual austenite. Additionally, in powder metallurgy studies [30,31] it has been reported to decrease strength, as excess alloy content causes porosity. However, in studies without heat treatment, the addition of Ni has increased the strength somewhat.…”

In this study, the effects of adding Ni in different ratios to Fe-matrix material containing C-Nb-V produced by powder metallurgy on microstructure, tensile strength, hardness and corrosion behaviors were investigated. Fe-C and Fe-C-Nb-V powders containing 5%, 10%, 13%, 15%, 20%, 30% and 40% nickel were pressed at 700 MPa and then sintered in an Ar atmosphere at 1400 °C. Microstructures of the samples were characterized with optical microscope, scanning electron microscope (SEM) and XRD. Corrosion behaviors were investigated by obtaining Tafel curves in an aqueous solution containing 3.5% NaCl. Mechanical properties were determined by hardness and tensile testing. While Fe-C alloy and Fe-C-Nb-V microalloyed steel without Ni typically have a ferrite-pearlite microstructure, the austenite phase has been observed in the microstructures of the alloys with 10% nickel and further. Yield and tensile strength increased with nickel content and reached the highest strength values with 13% Ni content. The addition of more nickel led to decrease the strength. Analysis of Tafel curves showed that corrosion resistance of alloys increased with increasing nickel concentration.

“…Groups of Fe-10wt%Ni-5wt%Cu samples, three specimens each, were fabricated via powder metallurgy technique. Metals powders were added together then mixed in stainless steel jars having stainless steel balls ( 3,6, and 10 mm diameter) with a weight ratio of the balls to the powder of about (10 to 1). For lubrication, 0.5wt% paraffin wax was added while a 5ml Hexane per 15gm was incorporated as a process control agent.…”

“…Nickel addition plays a crucial role in enhancing the mechanical characteristics of the Iron base P/M alloys. Behera, et al investigated that the addition of 1.5 wt% to 2.0 wt% of Nickel in various P/M alloys when sintering temperatures within the range of 900-1000°C enhances the mechanical and the relative density of such alloys [3]. Tekeli, et .al investigated the impact of addition of 2.0% Ni and 0.3% graphite on both the microstructure and dry sliding wear characteristics of iron-based powder metallurgy (PM) steels after applying various heat treatments.…”

Porosity of alloys produced by powder metallurgy remarkably reduces their strength. This study characterizes the effect of addition of 10wt%Ni and 5wt%Cu particles to Fe powder performing an Iron base alloy using P/M technique. The microstructure of the alloy was investigated using scanning electron microscope (SEM) equipped with energy dispersive X-ray spectroscopy (EDS). The relative density of the alloy fabricated at different parameters was investigated. Microstructural characterization of the alloy shows a low porosity and existence of spheroid oxide particles. Also EDS elemental analysis reveals a uniform distribution of Ni and Cu within the Fe matrix. In addition, the results reveal that the relative density and hardness increase with increasing the fabrication parameters; pressure and sintering temperature when the time is kept constant and their maximum values were obtained when that alloy fabricated at compaction pressure 700 MPa and sintering temperature 1200°C for 90 min.

“…in the sintered mn-Si steels, the formation of mn-Si oxide inclusions depends on the sintering conditions [31]. nickel can slightly decrease the temperature of liquid formation and increase the phase fraction of liquid [21,32]. addition of carbon and molybdenum to Fe-ni sintered alloys improves the distribution of nickel and forms a strong interaction between nickel and copper [33].…”

And mechAnIcAl ProPerTIes of Powder meTAllurgy sTeelsan experimental study was performed to assess the influences of aluminum content on the porosity, microstructure and mechanical properties of powder metallurgy steels. optical microscope equipped with the image processing software and the scanning electron microscope were employed to study the microstructure of investigated specimens. in order to find mechanical properties of specimens, Vickers hardness and compression tests were conducted. By increasing the aluminum content (from 0 to 4 wt. %), the porosity increases (from 6.01% to 8.43%). The microstructure of specimens contains aluminum phase distributed between the boundaries of agglomerated iron particles, ferrite, and pearlite. By increasing the aluminum content, stress-strain curves shift significantly downwards, and the modulus of elasticity, elongation, yield stress, and Vickers hardness reduce from 1.82 to 0.86 gPa, 32.1 to 17.8%, 138.1 to 28.2 mPa, and 127.7 to 26.8 HV, respectively.
