Brinell hardness (HB) nrog ib txoj kab uas hla ntawm cov pob steel los yog tungsten carbide npas, nias rau hauv cov qauv saum npoo ntawm ib qho kev ntsuas predetermined (F), tom qab predetermined tuav lub sij hawm tom qab poob kev xeem quab yuam, txoj kab uas hla ntawm qhov ntsuas tus qauv nto indentation. (L).Brinell hardness test force muab faib los ntawm qhov indentation spherical nto cheeb tsam quotient.Rau HBS (Pob Pob Pob Pob) lub tsev N / mm2 (MPa).Cov mis yog: qhov twg: F - nias rau hauv cov hlau saum npoo ntawm cov qauv ntsuas quab yuam, N;D - kuaj steel pob txoj kab uas hla, mm;d - indentation nruab nrab txoj kab uas hla mm.Brinell hardness tau ntsuas ntau qhov tseeb thiab txhim khu kev qha, tab sis feem ntau HBS tsuas yog siv 450N / mm2 (MPa) lossis tsawg dua ntawm cov khoom siv hlau, rau cov hlau nyuaj, lossis cov ntawv nyias NA.Cov qauv hlau, Brinell hardness yog qhov siv dav tshaj plaws, thiab feem ntau tau hais tias qhov hardness ntawm cov khoom siv, qhov indentation txoj kab uas hla d ob qho tib si intuitive thiab yooj yim.

Brinell hardness yog txoj kev siv dav tshaj plaws hauv carbon steel yeeb nkab hardness kuaj, .Cov qauv no siv qhov ntxov tshaj plaws, vim nws cov ntawv luam tawm, thiab yog li qhov hardness qhov tseem ceeb cuam tshuam los ntawm cov qauv koom haum microsegregation cov khoom xyaw tsis sib xws, qhov kev ntsuam xyuas cov ntsiab lus sprinkle me me, zoo reproducibility, tuaj yeem cuam tshuam lub hom phiaj hardness ntawm cov khoom.

Lub hauv paus ntsiab lus: Nyob rau hauv ib tug predetermined nrhiav kom tau quab yuam, ib tug tej txoj kab uas hla ntawm lub pob steel yog nias rau hauv cov qauv nto kom tswj tau ib lub sij hawm, thiab ces tshem tawm cov kev quab yuam, lub siab imprint txoj kab uas hla ntsuas nyob rau hauv tus qauv nto, yuav xam raws li nyob rau hauv lub sij hawm. txoj kab uas hla ntawm lub siab imprint siab cim lub gravure cheeb tsam.Brinell hardness test force muab faib los ntawm qhov indentation spherical nto cheeb tsam quotient.Chav tsev 9.807N / mm.Lub indentation Loj steel pob nias rau hauv qhov sib sib zog nqus, qis hardness qhov tseem ceeb;vice versa hardness qhov tseem ceeb los koom.
