ENDPLATE FOR HOT ISOSTATIC PRESSING CANISTER, HOT ISOSTATIC PRESSING CANISTER, AND HOT ISOSTATIC PRESSING METHOD

摘要

An endplate for a hot isostatic pressing canister comprises a central region, and a main region extending radially from the central region and terminating in a corner about a periphery of the endplate. The thickness of the endplate increases along the main region, from the central region to the corner, defining a taper angle. The corner includes an inner surface comprising a radiused portion by which the main region smoothly transitions into the lip. A hot isostatic pressing canister including at least one of the endplates also is disclosed, along with a method of hot isostatic pressing a metallurgical powder using the hot isostatic canister.

主权项

1. A method for hot isostatic pressing a powdered material, the method comprising:
disposing at least one metallurgical powder in a canister through a fill stem, wherein the canister is a hot isostatic pressing canister comprising
a cylindrical body including a circular first end and a circular second end,a first endplate attached to the circular first end of the cylindrical body, the
first endplate comprising
a central region, anda main region extending radially from the central region and terminating in a corner about a periphery of the endplate, the corner including a peripheral lip configured to mate with the cylindrical body,wherein a thickness of the endplate increases from the central region to the corner and defines a taper angle, andwherein an inner surface of the corner includes a radiused portion by which the main region transitions into the peripheral lip,a fill stem attached to the first endplate, anda second endplate attached to the circular second end of the cylindrical body; evacuating at least a portion of air from the canister through the fill stem; hermetically sealing the canister; and hot isostatically pressing the canister.
