Abstract Minimizing the residual stress and deformation of manufactured product consequent to selective laser melting (SLM) process is always a primary focus in realm additive manufacturing. This paper studied influence different scanning strategies on thermal-mecha nical characteristics SLM Ti6Al4V. Numerical simulation experimental tests were employed concerning three process: Z-shaped, outer spiral, inner spiral. Allowing for latent heat phase change, thermal radiation, convection effect,...
To account for the microstructure evolution corresponding to changed scanning speed, thermal-fluid dynamic model of meltpool during selective laser melting (SLM) process Ti6Al4V was established by numerical method study thermal characteristics and melt flow behavior. Results showed that increasing speed would result in a lower peak temperature but higher heating cooling rate on specimen. Both size its duration were reduced with increased velocity. Typically, waved solid/liquid interface...
The application of a pulsed magnetic field (PMF) during metallurgy solidification process has proven to be an effective method in refining the grain size and improving mechanical performance material. However, fewer works were reported realm laser additive manufacturing (LAM) mechanism refinement consequent PMF is still unclear. In this work, numerical models developed study thermal-fluid characteristics Ti-alloy melt pool generated scanning under effect combined direct current (DC) electric...
