(2) Nnwale na-adịghị emebi emebi nnyocha:

a. Ultrasonic flaw detection UT: Ọ na-enwe mmetụta maka nrụrụ elu na n'ime ime nke ihe dị iche iche nwere ihe edo edo.
b. Nnwale Eddy ugbu a ET (induction electromagnetic) na-enwekarị mmetụta maka ntụpọ (oghere nwere oghere).
c. Ihe Nnwale Igwe Igwe Igwe Ọdụdọ MT na Flux Leakage Test: Nnwale ndọta dabara adaba maka nchọpụta elu na ntụpọ dị nso nke ihe ferromagnetic.
d. Nchọpụta ntụpọ eletrọnịkị ultrasonic: Ọ dịghị ihe jikọrọ ọnụ achọrọ, yana enwere ike itinye ya na ọnọdụ okpomọkụ dị elu, ngwa ngwa dị elu, nchara nchara siri ike ịchọpụta ntụpọ elu.
e. Nchọpụta ntụpọ penetrant: fluorescence, agba agba, nchọpụta nke ntụpọ elu igwe nchara.

3. Nyocha ihe mejupụtara kemịkalụ:nyocha nke kemịkalụ, nyocha ihe eji eme ihe (ngwa CS infrared, spectrometer ọgụgụ ozugbo, enweghị akụrụngwa, wdg).

(1) Ngwa CS infrared: Nyochaa ferroalloys, akụrụngwa na-eme nchara, yana ihe C na S na nchara.
(2) spectrometer na-agụ kpọmkwem: C, Si, Mn, P, S, Cr, Mo, Ni, Cn, Al, W, V, Ti, B, Nb, As, Sn, Sb, Pb, Bi n'ụdị nnukwu.
(3) N-0 akụrụngwa: nyocha ọdịnaya gas N, O.

4. Nyocha ọrụ njikwa ígwè

(1) Nnwale ule: tụọ nrụgide na nrụrụ, chọpụta ike (YS, TS) na ntinye aka plasticity (A, Z) nke ihe. Longitudinal na transverse sample ọkpọkọ ngalaba, arc udi, okirikiri sample (￠10, ￠12.5) obere dayameta, mkpa mgbidi, nnukwu dayameta, oké mgbidi calibration anya. Cheta na: The elongation nke sample mgbe agbajikwa metụtara size nke sample GB / T 1760.
(2) Nnwale mmetụta: CVN, notch C ụdị, V ụdị, ọrụ J uru J / cm2 ọkọlọtọ sample 10 × 10 × 55 (mm) na-abụghị ọkọlọtọ sample 5 × 10 × 55 (mm).
(3) Nnwale siri ike: Brinell hardness HB, Rockwell hardness HRC, Vickers hardness HV, wdg.
(4) Nnwale hydraulic: ule nyocha, oge nkwụsi ike, p = 2Sδ / D.

5. Ihe nleba anya nke usoro nyocha nke igwe anaghị agba nchara

(1) Nnwale na-enwu enwu: ihe nlele okirikiri nke nwere ụdị C (S / D> 0.15) H = (1 + 2) S / (∝ + S / D) L = 40 ~ 100mm, ọnụọgụ deformation kwa nkeji ogologo = 0.07 ~ 0.08
(2) Nnwale mgbanaka mgbanaka: L=15mm, ọ nweghị mgbape tozuru oke
(3) Nnwale ọkụ na curling: taper etiti bụ 30°, 40°, 60°
(4) Nnwale na-ehulata: Ọ nwere ike dochie ule flattening (maka ọkpọkọ buru ibu)

6. Metallographic analysis nke ọkpọkọ enweghị nkebi
Nnwale ịdị elu dị elu (nyocha microscopic), ule dị elu dị ala (nyocha macroscopic) ule ntutu dị ka ụlọ elu iji nyochaa nha ọka nke ihe ndị na-abụghị nke ọla, na-egosipụta anụ ahụ dị ala na ntụpọ (dịka nkwụsị, nkewa, afụ subcutaneous, wdg. ), ma nyochaa ọnụọgụgụ, ogologo na nkesa ntutu isi.

Ọdịdị dị ala (macro): ntụpọ ọcha a na-ahụ anya, inclusions, afụ subcutaneous, ntugharị akpụkpọ ahụ na delamination anaghị anabata na nyocha dị ala nke cross-section acid leaching test nke ọkpọ ígwè enweghị nkebi.

Nzukọ dị elu (microscopic): Jiri igwe igwe eletrọn dị elu were nyocha. Nnwale ntutu isi ụlọ elu: nwalee ọnụọgụgụ, ogologo na nkesa ntutu isi.

Otu ọ bụla nke ọkpọkọ nchara na-abanye n'ime ụlọ ọrụ ahụ ga-esonyere ya na akwụkwọ mmado na-egosi iguzosi ike n'ezi ihe nke ihe dị n'ime batch nke ọkpọkọ igwe anaghị agba nchara.
