Cov khoom siv kho tshuab ntawm cov ntaub ntawv hais txog cov yam ntxwv kho tshuab ntawm cov ntaub ntawv nyob rau hauv ntau qhov chaw sib txawv (kub, av noo, nruab nrab), nyob rau hauv ntau yam kev thauj khoom sab nraud (tensile, compression, bending, torsion, impact, alternating stress, thiab lwm yam).
Cov khoom siv kho tshuab kuaj suav nrog qhov nyuaj, lub zog thiab elongation, kev cuam tshuam toughness, compression, shear, torsion test thiab lwm yam.
Qhov kev xeem tawv yog hais txog Brinell hardness, Rockwell hardness, Vickers hardness, microhardness; Qhov kev xeem lub zog yog lub zog tawm thiab lub zog tensile. Kev xeem tensile raws li cov qauv:
Hlau: GB / T 228-02, ASTM E 88-08, ISO 6892-2009, JIS Z 2241-98
Tsis yog 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 sim uas siv ntau yog cov no: tshuab sim khoom siv thoob ntiaj teb, tshuab sim kev cuam tshuam, tshuab sim kev qaug zog, Whole Rockwell hardness tester, Vickers hardness tester, Brinell hardness tester, Leeb hardness tester.
Kev kuaj xyuas cov khoom siv hlau yog ib txoj hauv kev tseem ceeb rau kev tsim thiab txhim kho cov khoom siv hlau tshiab, txhim kho cov khoom siv zoo, ua kom muaj peev xwm ntau tshaj plaws ntawm cov khoom siv (xaiv qhov kev ntxhov siab tsim nyog), tshuaj xyuas qhov tsis ua tiav ntawm cov khoom hlau, xyuas kom meej tias muaj kev tsim qauv zoo ntawm cov khoom hlau thiab kev siv thiab kev saib xyuas cov khoom hlau kom muaj kev nyab xeeb thiab txhim khu kev qha (saib cov yam ntxwv ntawm cov khoom siv hlau).
Cov khoom sim ib txwm muaj xws li: Qhov nyuaj (Brinell hardness, Rockwell hardness, Leeb hardness, Vickers hardness, thiab lwm yam), qhov kub thiab txias hauv chav, qhov kub siab tensile, qhov kub qis tensile, khoov, cuam tshuam (cuam tshuam rau qhov kub thiab txias hauv chav, cuam tshuam rau qhov kub qis, cuam tshuam rau qhov kub siab) qaug zog, khob, kos duab thiab rub tawm, khob khob, reaming, compression, shear, torsion, flattening, thiab lwm yam. Kev sim cov khoom siv kho tshuab ntawm cov khoom siv kho tshuab thiab cov phaj vuam (raj) cov khoom siv kho tshuab (deformation, tawg, adhesion, creep, qaug zog), thiab lwm yam.
