National Standard of the People's Republic of China
High-temperature alloy bars crack low-magnification acid diffusion test methodMetieds of azid e1of tesi for longitudinalTacrostructurgz.of htit=retietingaucerslloybtreThis standard is applicable to the method of electric stop, reading the high-temperature alloy and the film building financial service low-energy test group, the test measures and its effect of the sound
1.1 or the selected later position is determined in the center of the technique, GD.T 14949.1-52
rHn Jat. a
1-2 The report allows the selection of the method, the shape of the test machine must be, .3 The low-energy
1.4 The style should be based on the phase card water to the specification of the heat treatment system after the retreat system. 1.6 with 1 this, the test surface heart (the front car 2+), to test the light is not used for
2, the root test
2.1 collect the nature of the reagent (but must be the source of the night group correction period, Jiang standard. No original) A degree (CuS0..:0), *g
acid flow (ratio not less than ten! 3): 35m1
degree (ratio not less than 1.1?) 560m
can be allowed to 60 when matched, better consultation, first will be, salt gland,
2.2 gel Sheng when using three benefits to eliminate the cold reagent! Of course, in the test format, the test can be completely determined by the account H organization: also the heart of the Sichuan North low secretion card test is carried out according to the test (up to the page order), the time required for the reagent varies according to the new and old brand, : 6 5 ~ 3 heart points, 2-5 sex pressure fast, when the result can be 5-5% over release, etc. can be achieved. After the format, use a fan to taste or use the original water to dry. 3 sticky with the determination || tt || 31 use the internal determination, the door can be 10 full magnifying glass nearly 3.2 to obtain the combination of fast, high magnification period of the new detection reagent attached to the negative assessment. The picture is collected G4033.GHGH0, H50GH49, GFTGIT4GI3. The reduction is the most northern station of the G1408 system. 2 is the gold content of GH4337, GH4040 large product grains. 9 is the edge wave rental point with boundary wind, for (, H433T, (H4042 will be active, the end of the material body is deep and classic, the material diameter is not allowed to be too large, the figure is the central grain product with qualified list, the figure is greater than 2 [40R, 4 gold group grid institute
