Ziziphi iimpembelelo ze-alloying elements kwi-aluminium bronze

Iimpembelelo ze-alloying elements kwiubhedu aluminiyamzezi zilandelayo:

I-Iron Fe:

1. Isinyithi esigqithisileyo kwi-alloy siya kukhupha i-neliti efana ne-FeAl3 i-compounds kwi-tissue, okubangelwa utshintsho kwiimpawu zomatshini kunye nokuwohloka kokumelana nokubola;

2. Intsimbi iyacotha ukusasazwa kwee-athomu kubhedu lwe-aluminiyam kwaye yandisa ukuzinza kwe-dobech. Isixa esincinci sentsimbi sinokunqanda into ethi "self-annealing" ye-brittleness ye-bronze ye-aluminium, iyancipha kakhulu i-brittleness ye-alloy, kwaye ukongeza umxholo we-0.5-1% wenza ukuba ingqolowa ibe bhetele.

Manganese Mn:

1. I-Hot rolling cracking ingancitshiswa ngokudibanisa i-0.3-0.5% ye-manganese kwi-binary aluminium bronze;

2. Xa umlinganiselo othile wesinyithi wongezwa kwi-manganese-aluminium yobhedu, isinyithi sinokucokisa ingqolowa, kwaye kukho iinqununu ezintle ze-Fe-aluminium compounds kwi-microstructure, ephucula iimpawu zomatshini kunye nokumelana nokugqoka, kodwa kunciphisa umphumo we-manganese kwi-dobech stabilization.

I-Tin Sn:

1. Akukho ngaphezu kwe-0.2% ye-tin eya kutshintsha ukuxhathisa kwe-corrosion yesigaba esinye se-aluminiyam yobhedu kumphunga kunye nomoya one-acidic kancinane.

IChromium Cr:

1. Isixa esincinci sechromium esongeziweyo kwibronzi ye-aluminiyam yokubini iluncedo,

2. Thintela ingxubevange yokufudumeza ukukhula kweenkozo, kwaye uphucule ngokubonakalayo ubulukhuni bengxubevange emva kokufakwa.

3. Izinto ze-alloying zichaphazela izinto zobhedu olumhlophe

Zinc Zn:

1. Isixa esikhulu se-soluble kwi-alloy-nickel alloy, dlala indima yokuqinisa isisombululo esiqinileyo, ukuphucula amandla kunye nobunzima, ukwandisa ukuxhathisa kwe-corrosion.

Ngokubanzi, izinto zomhlaba ezinqabileyo azinakunyibilika ngobhedu, kodwa isixa esincinci sesinyithi somhlaba esinqabileyo, nokuba sidityaniswe sisodwa okanye sikwimo yomhlaba onqabileyo oxubeneyo, ziluncedo kwiipropathi zomatshini zobhedu, kwaye zinefuthe elincinci kumbane wobhedu. Izinto ezinjalo zinokwenza iikhompawundi eziphezulu zokunyibilika kunye nokungcola okufana nelothe kunye ne-bismuth ngobhedu, zenze amasuntswana amahle angqukuva asasazwa kwinkozo, ukucocwa kweenkozo kunye nokuphucula iplastiki yobushushu obuphezulu bobhedu. Ngamanye amazwi, i-elongation kunye ne-shrinkage ye-Cu alloy kwi-800 inyuke kakhulu ngokunyuka komxholo we-cerium.
