Cov khoom siv ntawm cov khoom siv xa mus rau cov yam ntxwv ntawm cov khoom siv nyob rau hauv ib puag ncig sib txawv (kub, av noo, nruab nrab), nyob rau hauv ntau yam khoom siv sab nraud (tensile, compression, bending, torsion, impact, alternating stress, etc.).
Cov khoom siv kho tshuab ntsuas muaj xws li hardness, lub zog thiab elongation, cuam tshuam toughness, compression, shear, torsion test thiab lwm yam.
Lub hardness test yog hais txog Brinell hardness, Rockwell hardness, Vickers hardness, microhardness; Kev ntsuas lub zog yog tawm lub zog thiab lub zog tensile. Tensile xeem raws li cov qauv:
Hlau: GB / T 228-02, ASTM E 88-08, ISO 6892-2009, JIS Z 2241-98
Tsis-hlau: ASTMD 638-08, GB / T 1040-06, ISO 527-96, ASTMD 5034-09, ASTMD 638-08, GB / T 1040-06, ISO 527-96
Cov khoom siv uas siv ntau tshaj plaws yog cov no: cov khoom siv thoob ntiaj teb kev sim tshuab, kev ntsuas kev cuam tshuam lub tshuab, kev sim qaug zog, Tag Nrho Rockwell hardness tester, Vickers hardness tester, Brinell hardness tester, Leeb hardness tester.
Kev ntsuam xyuas cov khoom siv hlau yog ib qho tseem ceeb rau kev txhim kho thiab txhim kho cov khoom siv hlau tshiab, txhim kho cov khoom zoo, ua kom muaj peev xwm ntawm cov khoom siv (xaiv qhov tsim nyog qhov kev ntxhov siab), txheeb xyuas qhov tsis ua hauj lwm ntawm cov hlau qhov chaw, kom ntseeg tau tias tsim nyog tsim ntawm cov khoom hlau. thiab kev nyab xeeb thiab txhim khu kev qha siv thiab tu cov khoom siv hlau (saib cov yam ntxwv ntawm cov khoom siv hlau hlau).
Cov khoom kuaj niaj hnub yog: Hardness (Brinell hardness, Rockwell hardness, Leeb hardness, Vickers hardness, thiab lwm yam), chav tsev kub tensile, kub tensile, kub tsis tshua muaj tensile, dabtsi yog khoov, cuam tshuam (chaw kub cuam tshuam, tsis tshua muaj kub cuam tshuam, kub kub cuam tshuam. ) qaug zog, khob, kos duab thiab kos duab load, khob khob, reaming, compression, shear, torsion, flattening, thiab lwm yam. Fastener mechanical properties test and welded phaj (tube) mechanical properties (deformation, fracture, adhesion, creep, fatigue), thiab lwm yam .
