27、roduction or networking permitted without license from IHS-,-,-AMS 5655E SAE AMS 5655E- 5 -3.4.2.4.4 Decarburization shall be measured by the metallographic method, by HR 30N scale hardness testing method, or by a traverse method using microhardness testing in accordance with ASTM E 384. The hardnes
28、s method(s) shall be conducted on a hardened but untempered specimen protected during heat treatment to prevent changes in surface carbon content. Depth of decarburization, when measured by a hardness method, is defined as the perpendicular distance from the surface to the depth under that surface b
29、elow which there is no further increase in hardness. Such measurements shall be far enough away from any adjacent surface to be uninfluenced by any decarburization on the adjacent surface. In case of dispute, the depth of decarburization determined using the microhardness traverse method shall gover

31、ock is forged to a test coupon having a degree of mechanical working not greater than the forging and heat treated as in 3.3, specimens taken from the heat treated coupon shall conform to the requirements of 3.4.2.1, 3.4.2.2, and 3.4.2.3. If specimens taken from the stock after heat treatment as in
