Pearlite kev ua yeeb yam tseem ceeb
Qhov ua tau zoo ntawm pearlite yog nruab nrab ntawm ferrite thiab cementite, thiab lub tawv yog zoo dua. Nws lub zog tensile yog 750 ~ 900MPa, 180 ~ 280HBS, elongation yog 20 ~ 25%, cuam tshuam zog yog 24 ~ 32J. Cov yam ntxwv ua tau yog nruab nrab ntawm ferrite thiab cementite, nrog lub zog loj, hnyav hardness, zoo plasticity thiab toughness σb = 770MPa, 180HBS, δ = 20% ~ 35%, AKU = 24 ~ 32J).
Cov cuab yeej ua tau zoo txhua yam ntawm pearlite zoo dua li ntawm ferrite lossis cementite ib leeg. Cov cuab yeej ua tau zoo ntawm pearlite yog nruab nrab ntawm ferrite thiab cementite, thiab lub zog thiab tawv yog ntsis thiab tsis nkig, vim tias qhov ntau ntawm cov cementite hauv pearlite muaj tsawg dua li tus nqi ntawm ferrite.
