Kev txhais ntawm Ductility hauv tooj liab Alloys

1. Kev txhais ntawm Ductility hauv tooj liab Alloys

Ductility hais txog cov khoom muaj peev xwm ua taudeform plastically nyob rau hauv tensile kev nyuaj siab yam tsis muaj fracturing-tshwj xeeb tshaj yog, lub peev xwm yuav tsum tau ncab mus rau hauv cov xov hlau (kos duab) los yog zoo li tus rau hauv cov ntaub ntawv nyuaj (stamping, dabtsi yog khoov, sib sib zog nqus kos duab) thaum tuav cov qauv kev ncaj ncees. Rau tooj liab alloys, ductility yog xam los ntawm ob qhov tseem ceeb metrics (raws li ASTM E8 / E8M qauv):

Elongation ntawm Break (%EL): Qhov feem pua nce ntawm qhov ntev ntawm cov qauv kuaj ua ntej tawg (piv txwv li, 30% EL txhais tau tias cov khoom ncav cuag 30% ntawm nws qhov qub ntev).

Qhov txo qis ntawm cheeb tsam (% RA): Qhov feem pua txo qis hauv cross- ntu ntu ntawm qhov chaw tawg, qhia tias cov khoom muaj peev xwm "caj dab" (nyias hauv zos) tsis tawg.

Ductility yog ze ze rau lub alloy lub microstructure (grain loj, theem muaj pes tsawg leeg) thiab ua lub xeev:

Annealed (O) npau taws: Siab tshaj plaws ductility, raws li kev kho cua sov relieves kev ntxhov siab nyob rau hauv thiab refines nplej.

Txias- ua haujlwm (H) tempers: Ductility txo qis nrog kev ua haujlwm txias (piv txwv li, H24=ib nrab-nyuaj, H14=puv- nyuaj) vim muaj zog tawv.

Alloying khoom: Tsawg zinc (Zn), tin (Sn), lossis txhuas (Al) cov ntsiab lus feem ntau khaws cia ductility; high alloying los yog txhuas (Pb) ntxiv (rau machinability) yuav txo nws me ntsis.

Cov Lus Cim Tseem Ceeb rau Kev Tsim Khoom: Cov khoom siv tooj liab yog ib qho tseem ceeb rau cov txheej txheem uas yuav tsum tau muaj cov yas deformation tseem ceeb (piv txwv li, sib sib zog nqus- kos cookware, hluav taws xob xov hlau, stamped connectors) raws li lawv txo qhov kev pheej hmoo ntawm tawg, tearing, los yog springback.

2. Siab -Ductility Copper Alloy Qib rau kos duab / stamping

Hauv qab no yog cov qib zoo tshaj plaws tooj liab alloy rau kev kos duab (hlau, pas nrig, raj) thiab stamping (daim ntawv, sawb) daim ntawv thov, qeb los ntawm ductility (annealed temper, O). Tag nrho cov txiaj ntsig ua tau raws li ASTM B301 ( tooj dag), ASTM B124 (bronze), thiab ASTM B194 (tooj liab-nickel) cov qauv, nrog cov qauv elongation ntawm kev tawg (%EL) thiab cov xwm txheej tseem ceeb ntawm daim ntawv thov:

Kev txiav txim siab tseem ceeb rau Kev Lag Luam Txawv Tebchaws & Kev Tsim Khoom:

Temper xaiv: Qhia meej "annealed (O)" temper rau siab tshaj plaws ductility hauv kev kos duab / stamping. Tsis txhob txias - ua hauj lwm tempers (H24, H14) tshwj tsis yog tias cov txheej txheem yuav tsum muaj lub zog me me nrog kev deformation tsawg.

Alloy txwv: Lead-muaj cov tooj dag (piv txwv li, C36000, %EL=15-20%) muaj cov ductility qis dua thiab tsis pom zoo rau kev kos duab sib sib zog nqus-tso tseg rau kev stamping yooj yim lossis machining.

Tus nqi -Cov txiaj ntsig: C11000/C26000 muab qhov zoo tshaj plaws sib npaug ntawm ductility thiab tus nqi rau feem ntau cov ntawv thov kev lag luam; C10200 yog qhov zoo dua rau siab -purity lossis corrosion-sensitive siv.

Cov ntaub ntawv no yog tsim los rau kev sib txuas lus hauv cov khoom siv hlau txawv teb chaws, nrog cov ntsiab lus meej, cov qauv siv, thiab daim ntawv thov - tsom cov ntsiab lus los txhawb cov neeg siv khoom nug, xaiv cov khoom, thiab kev txiav txim specifications.
