Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a high pressure turbine disk hub with reduced axial stress and a method for reducing axial stress. SOLUTION: A gas turbine engine disk that includes centrally disposed disk hubs 21, 24, 56, 74, 94, 114 having integrally-formed, radially outwardly extending webs 18, 20, 72, 92, 112 terminating at an outer end. The disk hubs 21, 24, 56, 74, 94, 114 have radially-displaced annular hub surfaces 76, 96, 116, 166 exposed to high pressure, high temperature discharge gases during engine operation. The radially-displaced annular hub surfaces 76, 96, 116, 166 act as an axial free surface mitigating the formation undesirable axial stress in the disk hubs 21, 24, 56, 74, 94, 114.
