Title: SYSTEMS AND METHODS FOR CONTROLLING MICROSTRUCTURE OF ADDITIVELY MANUFACTURED COMPONENTS
Abstract:
An additive manufacturing system includes a powder bed and at least one energy source configured to produce at least one energy beam for forming a build layer of a component from the powder bed. The additive manufacturing system further includes a computing device coupled to the at least one energy source. The computing device includes a processor and a memory device. The memory device includes instructions configured to cause the computing device to execute a manufacturing plan for manufacturing the component, receive component thermal data corresponding to at least a portion of the component during manufacturing of the component, and control the at least one energy beam in response to receiving the component thermal data to produce a predetermined microstructure within the portion of the component.
