The high cracking susceptibility is the major obstacle to the wide application of high gamma '-phase nickel -based superalloys in additive manufacturing. It is especially important to explore the effects of alloying elements during the nickel -based superalloys and establish a new alloy design criterion. In this work, a new nickel -based superalloys with crack -free and low porosity was fabricated by adjusting the content of solid -solution and precipitating elements of Inconel 738LC (IN738LC) alloy utilizing laser directed energy deposition (LDED) technology, achieving an increase in strength...
