I-Manganese Steel (intsimbi ephezulu ye-manganese)
Intsimbi ye-alloy equkethe ngaphezulu kwe-10% ye-manganese. Ngo-1882, waqala wafumana intsimbi ephezulu ye-manganese yombutho we-austititic, kwaye ngo-1883, iBritish Dofield (Rahadfield) ifumene ilungelo elilodwa lomenzi we-manganese. Intsimbi ephezulu ye-manganese inokwahlulwa ibe ziindidi ezimbini ngokohlukeneyo:
(1) Intsimbi enganyangekiyo. Olu hlobo lwensimbi iqulethe i-10% ye-15% ye-15% ye-manganese, kwaye umxholo wekhabhoni uPhakamileyo, ngokubanzi kwi-0.90% ~ 1.0%, uninzi lwayo ngaphezulu kwe-1.0%. Ubume bayo bekhemicali (%):
C0.90-1.50mn10.0-15.0
I-SI0.30 ~ 1.0 s 0.05 p 0.10 Olu hlobo lwensimbi ye-manganese ephezulu yeyona isetyenziselwa iBhodi yeCone, iBhodi yeLifa leMbumo, intloko ye-Rulit, njl.
I-thessing yezicubu zensimbi ephezulu ye-manganese idla ngokudityaniswa kwe-austedite, i-carbide nepearlite, kwaye ngamanye amaxesha inenani elincinci le-phosphorus. Inani le-carbide likhulu, lihlala livela kwinethiwekhi kumda wengqolowa. Ke ngoko, intsimbi ephakamileyo ye-manganese kwi-tishu ye-choce iBrittle kwaye ayinakusetyenziswa kwaye ifuna unyango oluqinileyo lwesisombululo. Indlela esetyenziswayo esetyenziswa ngobushushu i-SURRE i-stores sisisombululo, apho intsimbi ifuduswa yintsimbi ye-1050 ~ I-1100 isidanga, i-insung tishu, fumana i-tishu yesigaba esincinci, ukuze i-tishu igcinwe kubushushu begumbi. Emva konyango lobushushu, amandla, iplastikhi kunye nobushushu bensimbi iphuculwe kakhulu, ke le ndlela yobushushu ikwabizwa ngokuba yimpatho gadalala. After heat treatment, the mechanical properties are: σ b615~1275MPa σ 0.2340~470MPa ζ15%~85% ψ 15% ~ 45% a Kl 96 ~ 294 J / cm2 HBl80~225
Emva konyango lwesisombululo esiqinileyo, kuya kubakho inani elincinci le-carbide engafunekiyo, enokusetyenziswa xa ixabiso lincinci kwaye lihlangabezana nemigangatho yovavanyo.
