Dab tsi yog qhov cuam tshuam ntawm alloying ntsiab ntawm aluminium bronze

Cov teebmeem ntawm alloying ntsiab ntawmtxhuas bronzeyog raws li nram no:

Hlau Fe:

1. Cov hlau ntau dhau ntawm cov hlau yuav ua rau cov koob zoo li FeAl3 cov khoom sib txuas hauv cov ntaub so ntswg, uas ua rau muaj kev hloov pauv ntawm cov khoom siv dag zog thiab kev ua haujlwm tsis zoo ntawm corrosion;

2. Hlau slows qhov diffusion ntawm atoms nyob rau hauv aluminium bronze thiab ua rau kom dobech stability. Ib qho me me ntawm cov hlau tuaj yeem cuam tshuam qhov "self-annealing" tshwm sim ntawm brittleness ntawm txhuas bronze, txo cov brittleness ntawm cov hlau, thiab ntxiv 0.5-1% cov ntsiab lus ua rau cov nplej finer.

Manganese Mn:

1. Kub dov tawg yuav txo tau los ntawm kev ntxiv 0.3-0.5% manganese rau binary txhuas bronze;

2. Thaum muaj qee yam ntawm cov hlau ntxiv rau hauv manganese-aluminium bronze, hlau tuaj yeem kho cov nplej, thiab muaj cov khoom zoo ntawm Fe-aluminium compounds hauv microstructure, uas txhim kho cov khoom siv thiab hnav tsis kam, tab sis tsis muaj zog ntawm manganese ntawm dobech stabilization.

Tin Sn:

1. Tsis pub ntau tshaj 0.2% tin yuav hloov qhov corrosion kuj ntawm ib-theem txhuas bronze nyob rau hauv chav thiab me ntsis acidic cua.

Chromium Cr:

1. Ib qho me me ntawm chromium ntxiv rau binary aluminium bronze yog qhov zoo,

2. cuam tshuam cov alloy annealing cua sov grain loj hlob, thiab ho txhim kho lub hardness ntawm alloy tom qab annealing.

3. Alloying ntsiab cuam tshuam cov ntsiab lus ntawm tooj liab dawb

Zinc Zn:

1. Ib tug loj npaum li cas ntawm soluble nyob rau hauv tooj liab-nickel alloy, ua si lub luag hauj lwm ntawm cov khoom tov ntxiv dag zog rau, txhim kho lub zog thiab hardness, txhim khu lub corrosion kuj.

Feem ntau, lub ntiaj teb tsis tshua muaj cov ntsiab lus tsis tshua muaj txiaj ntsig nrog tooj liab, tab sis ib qho me me ntawm cov hlau tsis tshua muaj hauv ntiaj teb, txawm tias ntxiv ib leeg los yog hauv daim ntawv sib xyaw tsis tshua muaj ntiaj teb, muaj txiaj ntsig zoo rau cov khoom siv hluav taws xob ntawm tooj liab, thiab tsis tshua muaj kev cuam tshuam rau hluav taws xob conductivity ntawm tooj liab. Cov ntsiab lus zoo li no tuaj yeem tsim cov ntsiab lus siab melting point nrog impurities xws li txhuas thiab bismuth hauv tooj liab, tsim cov khoom zoo sib xws hauv cov nplej, ua kom zoo dua cov nplej thiab txhim kho cov kub kub plasticity ntawm tooj liab. Hauv lwm lo lus, qhov elongation thiab shrinkage ntawm Cu alloy ntawm 800 tau nce ntxiv nrog kev nce ntawm cov ntsiab lus cerium.
