“…The presence of these gaps indicates that precipitates such as MoC(N), CrC(N), and MoCrC(N) were separated from the surface during the tensile test. 37 This associated with the separation of carbide, nitride, and carbonitrides from the surface during the tensile test. 38 To summarize, an increase in yield and tensile strength and a decrease in elongation values were observed with the increase of Cr and Mo content.…”

The present study focuses on the microstructure, mechanical properties, and machining aspects of powder metallurgy (PM) steel containing different rates of chromium (Cr) and molybdenum (Mo). PM steel alloys were pressed at 700 MPa and sintered at 1400°C in a mixture of nitrogen and hydrogen atmosphere for 1 hour. While the precipitates and fracture surfaces of the samples obtained were examined by scanning electron microscope (SEM) and EDS analyzes, the grain size and phase distributions were also examined with an optical microscope. Moreover, tensile and hardness measurement tests were carried out to determine the mechanical properties of the samples with different ratios of Cr and Mo content. The milling experiments were also performed without using coolant in a CNC milling machine at different cutting parameters. The surface roughness (Ra), tool wear (Vb), and wear mechanism were investigated under these conditions. The outcomes of this study reveal that the yield and tensile strength values of the samples with the addition of Cr and Mo increased but the elongation value decreased. The results also stated that the most effective process parameter for both Vb and Ra was the workpiece material and the regression models developed to estimate the output parameters (Vb and Ra) give successful results with high determination coefficients (R2) of 98.05% and 98.11%, respectively.

“…The purpose of this research is to determine how different Al 2 O 3 reinforcements, both single and multilayer, affect the microstructural, mechanical properties of 316L stainless steel produced by powder metallurgy. Materials with near-bone qualities were created when the results obtained were investigated in terms of mechanical properties [5][6][7]16]. Material development investigations for prosthetic applications have been more serious recently.…”

“…In addition, the parts produced by the PM method have a smooth, clean surface close to the final shape compared to other methods. Stainless steels, on the other hand, are known as a frequently preferred material group in many sectors, such as the biomedical industry, due to their excellent mechanical properties, their ability to maintain their mechanical properties at high and low temperatures, as well as their excellent wear, and corrosion resistance [1][2][3][4][5].…”

This study developed new advanced composite materials consisting of functional grading of 316L and Al2O3 specially designed for potential biomedical applications. Mechanical properties were characterized by tensile testing, and microstructural properties by optical microscope, scanning electron microscope (SEM), and Energy Dispersive X-Ray (EDX) analyses. The uniform mixture in the material, up to 40% by weight of Al2O3, is uniformly distributed in the 316L matrix that shows disintegration. Then, samples with 2, 3, 4, and 5 layers were produced in functionally graded 6, 7, 8, and 9 material types, respectively. The layer thicknesses were formed with an average of 900 µm. The results show that new composite materials can be produced functionally using 316L and Al2O3 in a layered manner. As a result of the mechanical experiments, it has been observed that the tensile strength of the layered composite structures remains within the range of 91–191 MPa, depending on the layer type. It has been observed that the elongation varies between 3.16 and 12.46%. According to these results, the materials obtained are considered suitable for use as an alternative prosthetic material in biomedical applications. The tensile strength, % elongation of the Composition 7, and yield strength of functionally graded (316 + (316L-10 Al2O3) + (316L-20 Al2O3) + (316L-30 Al2O3)) material are 123 megapascals (MPa), 7.3%, and 111MPa, respectively, and according to the literature, the mechanical strength of human bone is very close to this composition properties.

“…In addition, compared to other processes, the parts made using the PM method have a clean, smooth surface that is near to the final shape. Conversely, because of their superior mechanical qualities, their capacity to retain those qualities at both high and low temperatures, and their overall great performance, stainless steels are recognised as a material group that is frequently chosen in various industries, including the biomedical industry [5][6][7][8][9][10][11][12][13][14].…”

Powder metallurgy (PM) has several technological applications in the automotive and aerospace industries, making it important for modern manufacturing. PM is needed in manufacturing for high productivity, geometric precision, surface quality, and material efficiency. Due to their wear and corrosion resistance and high strength, austenitic steels like SS316L are used in the aerospace, medical, automotive, and marine industries to make complex and custom parts. In this study, the microstructure and tribological characterization of PM-heat-treated SS316L+7Si were examined.
