| Abstract Scope |
Tungsten has unique applications in aerospace due to its high melting point and heat resistance. There is great interest in using it for hypersonic applications. However, tungsten is very difficult to manufacture due to its high melting point and high hardness. Additive Manufacturing (AM) has the potential to manufacture fully dense tungsten. Currently tungsten is alloyed with other materials when produce via AM to reduce cracking. Researchers at Ohio State and Open Additive developed a novel scan strategy using a pre-heat laser and a full melt laser to produce pure tungsten. By using a pre heat laser that was immediately followed by the melting laser, the cooling rate was reduced. Experimental results showed reduced cracking and improved density when the scan strategy was used. |
