Solution Heat Treatment
Inconel 783 forge material shall be solution heat treated by heating to a temperature within the range 2025 to 2050 °F (1107 to 1121 °C), holding at the selected temperature within ±25 °F (±14 °C) for a time commensurate with section thickness, and cooling at a rate equivalent to an air cool or faster
If forgings are not to be machined all over, heat treatment shall be performed in a suitable protective atmosphere or, when permitted by purchaser, a suitable protective coating may be applied to the forgings in lieu of using a protective atmosphere.
Solution Heat Treatment of inconel 783 forged bars Shall be not higher than 29 HRC, or equivalent , determined in accordance with ASTM E 18. Average Grain Size:Shall be as follows, determined by the comparative method of ASTM E 112. In case of disagreement, the intercept (Heyn) procedure shall be used.
Inconel 783 forged Bars and rings under 9 square inches (58 cm2) in cross-sectional area shall exhibit averagegrain size of ASTM No. 5 or finer. Areas of nonrecrystallized grains with an average grain size, determined
by the intercept method, of ASTM No. 3 to 5 are permitted but shall not account for more than 20% of the cross-section.
Inconel 783 forged Bars and rings 9 to 50 square inches (58 to 323 cm2), inclusive, in cross-sectional area and all forgings shall exhibit average grain size of ASTM No. 4 or finer. Areas of non recrystallized grains with an
average grain size, determined by the intercept method, of ASTM No. 2 to 4 are permitted but shall not account for more than 20% of the cross-section." Limitations on duplex grain structures as defined by ASTM E 1181 shall be as agreed upon by purchaser and vendor.
The product of Inconel 783 forged parts shall have the following properties after being precipitation heat treated by heating to 1550 °F ± 15 (843 °C ± 8), holding at heat for 2 to 4 hours, cooling at a rate equivalent to an air cool to room temperature, heating to 1325 °F ± 15 (718 °C ± 8), holding atheat for 8 hours ± 0.5, cooling at a rate of approximately 100 °F (56 °C) degrees per hour to 1150 °F ± 15 (621 °C ± 8), holding at 1150 °F ± 15 (621 °C ± 8) for 8 hours ± 0.5, and cooling at a rate equivalent to an air cool
Stress-Rupture Properties at 1200 °F (649 °C) of inconel 783 forged material Shall be as follows; testing of notched specimens and of combination smooth-and-notched specimens shall be performed in accordance with ASTM E 292 and testing of smooth specimens shall be performed in accordance with ASTM E 139
A standard cylindrical combination smooth-and-notched specimen conforming to ASTM E 292, maintained at 1200 °F ± 3 (649 °C ± 2) while a load sufficient to produce an initial axial stress of 85.0 ksi (586 MPa) or
higher is applied continuously, shall not rupture in less than 23 hours. The test shall be continued to rupture without change of load. Rupture shall occur in the smooth section and elongation of this section after
rupture, measured at room temperature, shall be not less than 8% in 4D for product 5.0 inches (127 mm) and under in nominal diameter or least distance between parallel sides and shall be reported for product
over 5.0 inches (127 mm) in nominal diameter and least distance between parallel sides.
As an alternate procedure, separate smooth and notched specimens, machined from adjacent sections of the same piece, with gage sections conforming to the respective dimensions shown in ASTM E 292, may be
tested individually . The smooth specimen shall not rupture in less than 23 hours and elongation after rupture, measure at room temperature, shall be as specified.
The notched specimen shall not rupture in less time than the companion smooth specimen but need not be tested to rupture.
The tests may be conducted using incremental loading. In such case, the load required to produce an initial axial stress of 85.0 ksi (586 MPa) or higher shall be used to rupture or for 23 hours, whichever occurs first. After the 23 hours and at intervals of 8 hours minimum thereafter, the stress shall be increased in increments of 5.0 ksi (34.5 MPa). Time to rupture, rupture location, and elongation requirements shall be as specified
Mean Coefficient of Linear Expansion: Shall not exceed 7.5 x 10-6 inch/inch/。F (13.5 x 10-6 mm/mm/°C) at 1200 °F (649 °C) using 77 °F (25 °C) as the reference temperature, determined in accordance with ASTM E 228.
