There is high demand from the industry to produce high performance products with less manufacturing time and customised design of products. Additive manufacturing (AM) technique has the immense potentiality and is gaining ground in shaping the next-generation world. The various materials that have been developed so far using AM technique include SS 316, γ-TiAl, IN718, Ti–6Al–4 V, AlSi10Mg, high entropy alloys, etc. However, in order to facilitate rapid acceptability of this technique and to achieve the desired performance of the product, it is necessary to have highly isotropic microstructure with low defect density. It could be achieved only from the thorough understanding of the stochastic nature of defects formation and the complex non-equilibrium microstructure evolution mechanism via control over the processing parameters. Additive manufacturing (AM) technique is basically rapid solidification process and hence involves phase transformation under non-equilibrium condition.
