Additive Manufacturing (AM) is believed to be an invasive technology into conventional manufacturing industries. Microstructure of the fabricated parts plays significant role in determining the mechanical properties. Microstructure evolution is determined by temperature gradient and velocity at the liquid-solid interface during the solidification of the meltpool. Highly transient phenomenon of solidification of melt pool is poorly understood for conditions during the process. Experimental understanding is difficult due to smaller space (microns) and time scales (milliseconds) involved. Hence, it is vital to employ numerical modeling techniques to understand the influence of input parameters on the melt pool dynamics. In this study, the influence of various heat source parameters on the microstructure evolution will be analyzed. Truchas code developed by Los Alamos National Laboratory, compatible of running in parallel across multiple processors is used to simulate the thermal model. Spatiotemporal variation of solidification parameters during the process will be understood and discussed.
