Properties other than those listed may be defined as specified in AMS2362. 3.6.2.1 Specimens, maintained at 1800 F 3 (982 C 2) while a load sufficient to produce an initial axial stress of 29.0 ksi (200 MPa) or higher is applied continuously, shall not rupture in less than

28、 23 hours. The test shall be continued to rupture without change of load. Elongation after rupture, measured at room temperature, shall be not less than 4% in 4D. 3.6.2.2 The test of 3.6.2.1 may be conducted using a load higher than required to produce an initial axial stress of 29.0 ksi (200 MPa) b

29、ut load shall not be changed while test is in progress. Time to rupture and elongation requirements shall be as specified in 3.6.2.1. 3.6.2.2.1 The test of 3.6.2.1 may be conducted using incremental loading. In such cases, the load required to produce an initial axial stress of 29.0 ksi (200 MPa) or

30、 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 2.5 ksi (17 MPa).

31、 Not applicable. 3.7 Quality 3.7.1 Castings, as received by purchaser, shall be uniform in quality and condition, sound, and free from foreign materials and from imperfections detrimental to usage of the castings. 3.7.1.1 Castings shall have smooth surfaces and shall be well cleaned. Metallic shot o

32、r grit shall not be used for final cleaning, unless otherwise permitted by purchaser. 3.7.2 Castings shall be produced under radiographic control. This control shall consist of radiographic examination of castings in accordance with ASTM E1742/E1742M until proper foundry technique, which will produc

33、e castings free from harmful internal imperfections, is established for each part number and of production castings as necessary to ensure maintenance of satisfactory quality. 3.7.3 When specified, castings shall be subjected to fluorescent penetrant inspection in accordance with ASTM E1417/E1417M.

34、3.7.4 Radiographic, fluorescent penetrant, and other quality standards shall be as agreed upon by purchaser and vendor. ASTM E192 may be used to define radiographic acceptance standards. SAE INTERNATIONAL AMS5397E Page 5 of 9 3.7.5 Castings shall not be peened, plugged, impregnated or welded unless

35、authorized by purchaser. 3.7.5.1 When permitted in writing by purchaser, castings may be in-process welded in accordance with AMS2694. 3.7.6 Grain Size 3.7.6.1 Grain Size Distribution Shall be substantially uniform, equiaxed, non-columnar grains without pronounced segregation of fine and coarse grai

QUALITY ASSURANCE PROVISIONS 4.1 Responsibility for Inspection The vendor of castings shall supply all samples for vendors tests and shall be responsible for the performance

37、of all required tests. Purchaser reserves the right to sample and to perform any confirmatory testing deemed necessary to ensure that the castings conform to specified requirements. 4.2 Classification of Tests 4.2.1 Acceptance Tests Tests for composition (3.1), tensile properties (3.6.1) and stress-

38、rupture properties (3.6.2) of separately-cast specimens, quality (3.7) and grain size (3.7.6) of castings, and when specified (See 8.4), tensile and stress-rupture properties of specimens integrally-cast or machined-from-castings are acceptance tests and shall be performed as specified in 4.3. 4.2.2

39、 Periodic Tests Radiographic soundness (3.7.2) is a periodic test and shall be performed at a frequency selected by the vendor unless frequency of testing is specified by purchaser 4.2.3 Preproduction Tests All technical requirements are preproduction tests and shall be performed on specimens or sam

40、ple castings as applicable (4.3) when a change in control factors occurs (4.4.2.2), and when purchaser deems confirmatory testing to be required. 4.3 Sampling and Testing The minimum testing performed by vendor shall be in accordance with the following: 4.3.1 One chemical analysis specimen or a cast

41、ing from each master heat shall be tested for conformance with Table 1; if 3.4.2.1 applies, test frequency shall be acceptable to purchaser. 4.3.2 Tensile property and stress-rupture tests shall be conducted to determine conformance with 3.6.1 and 3.6.2. Sampling and test frequency is dependent upon

42、 the type and origin of the specimen specified by purchaser (See 3.4.4 and 3.6) or selected by vendor (See 4.3.2.4). When 3.4.2.1 applies, specimen source and test frequency shall be acceptable to purchaser. 4.3.2.1 For separately-cast specimens in the as-cast condition, two specimens from each mast

43、er heat shall be tested; one for conformance to Table 2 and one for conformance to 3.6.2. 4.3.2.2 For integrally-cast specimens in the as-cast condition, two specimens shall be randomly selected from each lot and tested for conformance with properties specified by purchaser (See 3.6 and 8.4). SAE IN

45、 When size and location of specimens are not shown, two specimens shall be tested, one from the thickest section and one from the thinnest section. Once established under 4.4.2.2, test locations may be changed only as agreed upon by purchaser and vendor. 4.3.2.4 When acceptable to purchaser, specime

46、ns machined-from-casting may be used in lieu of both separately-cast and integrally-cast specimens, and integrally-cast specimens may be used in lieu of separately-cast specimens. In each case, the resultant properties shall conform to the requirements of 3.6 or to alternative requirements specified

47、 by purchaser (See 8.4). 4.3.2.4.1 When specimens are selected for test as in 4.3.2.4 from an origin other than that specified by purchaser, vendor shall include in the report of 4.5 a description of the source of the specimen that was tested. 4.3.2.5 When casting size, section thickness, gating met
