“…Besides, it allows the production of small, functional, incompatible, difficult-to-manufacture parts with low dimensional tolerance [3], so it is possible to fabricate parts that are ready for direct usage. Also, it is possible to prepare various steel alloys and modify the chemical composition of the materials with precision [4,5]. Therefore, P/M steels have been utilized to fabricate structural parts in the mechanical fields and automotive industry [6].…”

Developments in sintering of powder mixtures contributed growth of steel production via powder metallurgy. This study aims to improve the mechanical and tribological properties of carbon steels produced via powder metallurgy. For this purpose, P/M carbon steel was alloyed with 3 % Manganese. Then, this alloyed steel was reinforced with particles such as titanium carbide (TiC), titanium nitride (TiN) and titanium carbonitride (TiCN) in different proportions (0.5 and 1 %) and combinations. The effect of these additives on the mechanical properties of PM steels was determined by conducting tensile and hardness tests. Wear tests were performed to understand the tribological properties of samples. Also, microstructural properties, fracture surfaces, and worn surfaces of samples were examined using a Scanning Electron Microscope. Results show that the hardness and tensile strength of carbon steel increased by nearly 158 % and 62 % respectively, while the wear resistance improved by 4 times with the addition of 3 % Mn and 0.5 % TiCN.

“…Another important parameter for characterizing the wear behavior is the friction coefficient. The coefficient of friction (CoF) provides significant information about the tribological behavior of the sample [25]. The CoF values obtained during the wear tests under 15 N load are given in Fig.…”

The influence of quenching and tempering heat treatments on the microstructure and wear behavior of AISI H13 tool steel was investigated. The austenitization was carried out at 1050 • C. After austenitization, oil quenching, single tempering, and sequential double tempering treatments were carried out. The microstructure, hardness, and wear behavior of the samples were studied. Three different types of carbide particles, M23C6, MC, and M7C3, were determined in the microstructure. The sample, subjected to quenching, gave the highest hardness value. The double tempering process caused secondary hardening. After the abrasive wear tests, the greatest volume loss was observed in the as-received sample. With quenching and tempering heat treatments, the wear resistance of H13 steel increased significantly. The lowest volume loss among the applied heat treatments was obtained by quenching + double tempering.

“…The parts produced by this method have a less rough surface than the parts produced by other methods and often do not require secondary processing. Homogeneous distribution of the quality, completely controllable ingredient and content, and low unit cost make powder metallurgy as a unique production method in the production industry [8][9][10][11][12][13]. Thus, it was found that approximately 97 % of the material was used in mass production with PM.…”

The investigation of the effect of cu addition on the Nb-V microalloyed steel produced by powder metallurgy

et al. 2022

In this work, the effect of Cu content on the microstructures, mechanical properties and electrical conductivity of Nb-V added microalloyed powder metallurgy (PM) steels were investigated. Microalloyed steel samples were pressed at 750 MPa and sintered at 1400oC in argon atmosphere for 1 h. The grain size and phase distribution of the microalloy steels were determined by optical microscope. The precipitates and fracture surface of samples were analyzed with the help of SEM and EDS analyses. Tensile test, hardness test and electrical conductivity measurement were carried out for the Nb-V added microalloyed steel with different Cu content. Results indicated that 10 wt.% Cu added PM microalloyed steel showed the highest values in yield strength (YS) and ultimate tensile strength (UTS). However, when the amount of Cu content increased from 10 to 15 wt.%, YS and UTS decreased. Elongation also tends to decrease with increasing Cu content. Although the electrical conductivity in general increased with the addition of Cu, a decrease in some conductivity was observed in the addition of 15 wt.% Cu.
