Description
Summary:Inconel718 (In718) Nickel based super alloy is widely used in aerospace applications, marine and defensive applications, In most of the cases the products are subjected to different types of loads in their applications. The knowledge of mechanical properties is essential for the mechanical engineer, working with materials. In the current research, the samples are modeled using NX software and fabricated in two different orientations, Horizontal (thickness in z-direction) and Vertical (length in z-direction) by using DMLS process. The fabricated samples are then tested for their tensile strength, compression strength, Impact strength, Hardness, wear resistance and corrosion resistance. The results obtained from both the orientations clearly indicate that the tensile strength, wear resistance, corrosion resistance are high for horizontally fabricated samples and Hardness, Compression strength, Impact resistance are high for vertically fabricated samples.
