11、 J403. The bar shall be free of cracks and seams as determined by magnetic particle inspection. The steel shall be fine grained (ASTM grain size 5-8) and have hardenability in DI range of 2.5-2.9. 4.1.2 Forging Material The forgings shall exhibit uniform grain distribution with grain size not larger
12、 than ASTM grain size 5. They may be normalized to obtain the desired grain size. Prior to going into production, the forging grain flow shall be checked at the plane of parting line. The grain flow shall be uninterrupted and shall not show reversal of flow lines and kinks. If at any time there is a
13、ny change in forging dies or forging process, the grain flow shall be verified against the originally approved grain flow. Forgings shall be free from quench cracks, seams, laps or other defects detrimental to the performance of the parts. Forgings shall be shot cleaned and machined into finished pa
14、rts. 4.2 Heat TreatmentType I: Parts shall be quenched and tempered to a Brinell surface hardness of 229-269 HBW. Hardness at the mid-radius shall not be below 200 HBW. Parts shall be inspected by magnetic particle test method to ensure absence of quench cracks and other defects. Type II: Parts shal
15、l be induction hardened and tempered at 150C (300F) minimum in the areas designated on the engineering drawings. The hardness at the induction hardened surface shall be in the range 50-58 HRC. The expected induction hardening pattern is shown in Figure 1, which also shows the effective case depth me
16、asured to Rockwell 45 HRC at various locations in the induction hardened zone. 4.3 Microstructure Type I: The forged surface microstructure (decarburization removed) shall consist of 90% minimum tempered martensite. The total decarburization measured per SAE J 419 shall not exceed 0.25 mm (0.010 in)
17、. Total plus partial decarburization shall not exceed 0.64 mm (0.025 in). Type II: The induction hardened surface microstructure shall consist of 95% minimum martensite. There shall be no excessive grain coarsening from induction hardening. Intergranular oxidation shall not exceed 0.05 mm (0.002 in.
18、). The microstructure of the forged surface will be the same as Type I. Corporate Technical Standards.

Testing shall be performed w
20、ith parts assembled to the corresponding mating driveshaft components. One end of the assembly shall be held/fastened rigidly to the appropriate fixture plate and the torsional load applied through an electro-hydraulic load simulator having torque and displacement meters and servo valve.

The maximum static unbalance limits shall not exceed 360 grams-mm (0.5 ounces-inch) for flanges and 720 grams-mm (1.0 ounces-in) for yokes. Th
23、e desired balancing may be achieved by removing material by drilling some areas of the parts. Care must be taken to avoid drilling in the high stress areas. 4.6 Marking Unless otherwise specified on the drawing, marking shall be easily legible, positioned so as not to be removable by subsequent proc
