| Abstract | ||
| Powder metallurgy (PM) is a primarily used because of its relatively close capability and cost-achievement ratio. The automotive industry is considered a major market for the powder metallurgy industry, as it necessitates products having superior mechanical or part of the implementation on a global level. PM technology is undergoing considerable changes in manufacturing and materials research as automobile technologies transitions beyond classic gasoline - powered vehicles to new energy vehicles. Changes in automobile technologies has created both obstacles and opportunities for PM, as outlined in this article. The mechanical properties of FGM (Al-Ni-steel) sample were investigated using hardness and tensile tests. Transmission electron microscopy (SEM) and X-ray Diffraction Instrument analysis were also used to analyze the microstructure of FGMs in detail by using Xpert panalytical program. Tensile specimens were made from sintered cylindrical rods with a length of 150 mm size with diameter of 10 mm. Tensile samples with the circular section size of 1cm and a length of 3 cm are machined according to ASTM E-8M. Homogeneous beams comprising varied weight fractions of Al (aluminum), Ni (nickel), and 316 steel are fabricated and tensile tests are performed to estimate the elastic modulus of horizontally layered functionally graded (FGMs) rods. Each homogenous layer's density is also calculated experimentally. | ||
