In-situ hot working and heat treatment of additively manufactured metallic alloys

A hybrid manufacturing system, comprising:

• a workpiece platform upon which an object on the workpiece platform is to be manipulated;
• a heater configured to heat at least a portion of the object on the workpiece platform;
• a material deposition system for depositing material on the workpiece platform;
• a mechanical forming device controllable to selectively deform a designated portion of the object being built on the workpiece platform;
• and
• a controller configured to execute a program to perform a manufacturing operation on the object situated on the workpiece platform based upon a three-dimensional representation of the object, wherein the controller is operatively programmed to:
• control the material deposition system to lay a track of material according to the three-dimensional representation of the object;
• control the mechanical forming device to apply mechanical force to a targeted portion of the object while a heater is controlled to maintain the targeted portion of the object at a hot working temperature, wherein:
• the applied mechanical force closes porosity of material within the targeted portion of the object, changes the microstructure within the targeted portion of the object, or both;
• and
• the applied mechanical force causes a shape change within the targeted portion of the object;
• and
• compute a correction for a next track to be laid by the material deposition system based upon the shape change caused by the applied mechanical force comprising utilizing phase diagrams and intended properties to change the applied mechanical force for the next track.
