Abstract

The main objective of this paper is to experimentally and numerically detect the surface cracks in the round bar for Ni-Al- 315 steel superalloy and calculate the crack depth which induces the sintering of these alloys. Several factors have contributed to surface defects, such as metallurgical defects and notches. The surface crack orientation can be estimated at the observed crack increase by using displacement. Various crack aspect ratios, a/b, ranging from 0.0 to 1.0, and relative crack depth, a/D, ranging from 0.2 to 0.4, are considered. The superalloy (Ni, Al and 315 steel) has been successfully modified utilizing the powder metallurgical process. The specimens are typically made up of Six layers, starting with (Al, Ni) across one side and ending with (Ni-Al- 315 steel) on another. Transmission electron microscopy (SEM) Instrument analysis has been used to detect the surface cracks and analyze the microstructure of superalloy used in detail using the X-pert analytical program.
