Maheswaran Vattur Sundaram

Doktorand at Surface and Microstructure Engineering

My research area is to achieve higher densities through Hot Isostatic Pressing in case of powder metallurgical components made through conventional press and sinter route or via alternative manufacturing techniques (i.e. additive manufacturing, EBM and SLM). Also possibilities to HIP water atomized powder will be analysed.
