Grain refinement of Fe--Ti alloys fabricated by laser powder bed fusion

Grain refinement of Fe--Ti alloys fabricated by laser powder bed fusion

Grain structure control is essential in metal additive manufacturing. It is used to avoid anisotropic mechanical properties, hot cracking and to increase the strength via the Hall-Petch effect. Here we demonstrate the use of grain refining particles for grain control in ferritic alloys, specifically...
