摘要： An induction furnace assembly (10) comprising a chamber (12) having a mold (16); a primary inductive coil (20) coupled to the chamber (12); a susceptor (26) surrounding the chamber (12) between the primary inductive coil (20) and the mold (16); and a shield material (44) contained in a reservoir (40) coupled to or proximate the mold (16) between the susceptor (26) and the mold (16); the shield material (44) configured to attenuate a portion of an electromagnetic flux generated by the primary induction coil (20) that is not attenuated by the susceptor (26).

摘要： A process for directional solidification of a cast part comprises energizing a primary inductive coil (20) coupled to a chamber (12) having a mold (16) containing a material (24); generating an electromagnetic field (28) with the primary inductive coil (20) within the chamber (12), wherein said electromagnetic field (28) is partially attenuated by a susceptor (26) coupled to said chamber (12) between said primary inductive coil (20) and said mold (16); determining a magnetic flux profile (44) of the electromagnetic field (28) after it passes through the susceptor (26); sensing a component of the magnetic flux (44) in the interior of the susceptor (26) proximate the mold (16); positioning a mobile secondary compensation coil (40) within the chamber (12); generating a control field (42) from the secondary compensation coil (40), wherein said control field (42) controls said magnetic flux (44); and casting the material (24) within the mold (16).

摘要： A process for directional solidification of a cast part comprises energizing a primary inductive coil (20) coupled to a chamber (12) having a mold (16) containing a material (24); energizing a primary inductive coil (20) within the chamber (12) to heat the mold (16) via radiation from a susceptor (26), wherein the resultant electromagnetic field (28) partially leaks through the susceptor (26) coupled to the chamber (12) between the primary inductive coil (20) and the mold (16); determining a magnetic flux profile of the electromagnetic field (28); sensing a magnetic flux leakage (44) past the susceptor (26) within the chamber (12); generating a control field (42) from a secondary compensation coil (40) coupled to the chamber (12), wherein the control field (42) controls the magnetic flux (44) experienced by the cast part; and casting the material (24) within the mold (16) under the controlled degree of flux leakage (44).

摘要： A method of fabricating process-equivalent test specimens to an additively manufactured component includes generating a processing history model of a component, dividing the component into regions based on input data variations in processing history, wherein each region is characterized by an identified range of input data, determining additive manufacturing processing parameters needed to additively manufacture one or more test specimens that each mimic the processing history in one of the regions, and fabricating the one or more test specimens using the processing parameters determined.

摘要： An induction furnace assembly (10) comprising a chamber (12) having a mold (16); a primary inductive coil (20) coupled to the chamber (12); a layered susceptor (26) comprising at least two layers (40) of magnetic field attenuating material (44) surrounding the chamber (12) between the primary inductive coil (20) and the mold (16) to nullify the electromagnetic field (28) in the hot zone of the furnace chamber (12).
