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 under the conditions of 3.5.1 .2.3.1. The smooth specimen shall not rupture in less than 23 hours and elongation after rupture, measure at room temperature, shall be as specified in 3.5.1.2.3.1.The notched specimen shall not rupture in less time than the companion smooth specimen but need not be tested to rupture.
The tests of 3.5.1 .2.3.1 and 3.5.1.2.3.2 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 in 3.5.1.2.3.1.
The vendor of bars, forgings, and flash welded rings shall furnish with each shipment a report showing the vendor’s name and the country where the metal was melted (e.g., final melt in the case of metal processed by multiple melting operations) and the results of tests for composition and mean coefficient of linear expansion of each heat, and for hardness and average grain size for each lot of bars, forgings, and flash welded rings as solution treated, and for hardness, room temperature tensile properties and stress rupture properties of each lot of bars, forgings, and flash welded rings after precipitation heat treatment, and stating that the product conforms to the other technical requirements. This report shall include the purchase order number, heat and lot numbers,AMS5940D, size, and quantity. If forgings are supplied, the size and melt source of stock used to make the forgings shall also be included.SAE AMS 5940D pdf free download.
