Effect of TiB 2 Content on Crack Suppression Mechanisms and Microstructural Evolution of IN939 Superalloy Under Pulsed Laser Processing
High‐γ′ nickel‐based superalloy IN939 is highly susceptible to cracks during laser additive manufacturing, severely limiting its engineering applications. In this work, TiB 2 /IN939 composites were fabricated via pulsed‐wave (PW) laser processing by incorporating TiB 2 particles, and their effects on microstructu...
