Directed energy deposition for processing gas turbine engine components

A computer readable storage medium comprising instructions that, when executed, cause at least one processor to:

• control, based on a target height of a layer to be deposited on a component by directed energy deposition, an energy source directed at the component to advance an energy beam along a first path to form an advancing molten pool on the component, and
• control, based on the target height of the layer, a material delivery device to deliver a material to the advancing molten pool,
• wherein the material combines with the advancing molten pool to form a first raised track having an actual height, wherein the layer comprises the first raised track, wherein a deposited region of the component comprises the layer, and wherein the actual height affects a resultant microstructure within the deposited region.

The computer readable storage medium of 14, further comprising instructions that, when executed, cause the at least one processor to control the cooling rate by:

• controlling a pause time between a time at which the first raised track is formed and a time at which a second raised track is formed, and
• controlling a hatch spacing between the first raised track and the second raised track, wherein the layer comprises the second raised track, wherein controlling the pause time and controlling the hatch spacing regulates at least one of a molten pool temperature, a subsurface temperature of a subsurface region of the component within the deposited region, or a surface temperature of a surface region of the component within the deposited region.
