Effect of Powder Composition Characteristic Temperatures and Input Energy Density on Microstructure and Internal Stresses of Nickel- and Cobalt-Based Heat-Resistant Alloys Produced by Selective Laser Melting. Part 1
摘要
Analysis of published data on the effect of the exposure algorithms, energy, and scanning speed on the geometric characteristics of the molten pool and its fine structure, on the texture and grain structure of metallic materials synthesized by selective laser melting (SLM) is presented. A regression model describing the correlation between the required laser energy density and the powder composition characteristic temperatures during SLM of heat-resistant nickel- and cobalt-based alloys is obtained.
