In this research a short review of three advanced materials i.e. 18 Ni 300 Maraging steel, precipitation hardened stainless steel (PH stainless steel) and high entropy alloys (HEAs) is done that are currently being used in metal additive manufacturing along with an experimental investigation in which direct metal deposition (DMD) of precipitation hardened steel is performed to evaluate the effect of powder feed rate onto the deposited layer quality (wrt clad height, dilution and energy density). The aim is to review the high strength advanced materials which has been recently developed but yet not well investigated through additive manufacturing and to investigate the clad quality of deposited PH stainless Steel for variable powder feed rate keeping other process parameters constant.
