Application: Titanium grain refinement in additive manufacturing (Patent ID: US20240189899A1)
Lockheed Martin Corp. has developed a method for enhancing additive manufacturing using titanium and titanium alloy materials by inoculating the titanium material with ceramic particles to promote grain nucleation during the solidification process. This method aims to reduce grain asymmetry, establish equiaxed grain arrangements, improve ultrasonic inspection viability, and enhance the overall quality of objects made with titanium materials. The ceramic particles used include titanium diboride, tungsten carbide, and other ceramic materials, and can be introduced in powdered form or in a molten state to achieve homogeneity within the titanium material.
The composite material resulting from this method consists of titanium material with ceramic particles embedded within it, facilitating equiaxed solidification of grains in response to the melting and solidification process in additive manufacturing. The composite material aims to reduce grain asymmetry, improve grain nucleation, and enhance the quality of titanium objects produced through additive manufacturing processes like directed energy deposition and powder bed fusion. The ceramic particles can be mixed with the titanium material in ingot or powdered form, or inserted into a hollow core wire configuration for use as wire feedstock. Overall, this innovation by Lockheed Martin Corp. seeks to optimize the additive manufacturing process for titanium materials, resulting in high-quality objects with equiaxed grains at a sub-millimeter scale.
