Abstract

The process of destruction is the final stage of the behavior of the metal under load, and the resistance that the metal gives to the development of this process, largely determines its structural strength. The studies were performed on samples made of Inconel 718 powder material after standard heat treatment. Tests to determine the mechanical properties were performed in accordance with GOST 1497 on an INSTRON test machine and performed analytical calculations using QForm software at a stable running traverse speed of 2 mm / s. Geometric parameters were monitored using a 3-D scanner and Geometric Control X software. A comparison of the ideal technical diagram with the true technical diagram of the Inconel 718 material revealed that they differed. These discrepancies are explained by the fact that the experimental material tested for stretching, in fact, has a higher value of plastic characteristics by 30% due to the porosity in the experimental material.
