The Problems of Analyzing the Dependence of the Sizes of Structural Components of Samples Synthesized by the 3DMP Method on the Strategy of Wave Thermal Deformation Hardening

Abstract

The problems of analysis of metallographic images and the way to solve them using modern software for the analysis of metallographic images are described. In this paper, we consider the problem of analyzing the microstructure of parts obtained as a result of alternating surfacing operations by the 3DMP method and wave thermal deformation hardening (HTSH), based on the expansion of the technological capabilities of the previously known wave work hardening (WSH). The analysis of the characteristic dimensions of the structural components of the synthesized samples, hardened according to different strategies of HTFS, is carried out in the SIAMS software package in the "Multi-phase analysis" section. A brief explanation of the features of using the software for a particular case is given. As a result of metallographic studies using the SIAMS software of the microstructure of parts obtained as a result of alternating surfacing operations by the 3DMP method and HTDU, the characteristic sizes of particle colonies and fine particles of crushed dendrites in each deposited layer were determined, and the nature of the distribution of structural components over the cross section of the samples in the direction of surfacing was revealed.
