Ithonya lezinto zokungcola e-aluminium alloy

I-Agadium yakha i-Val11 Refractional Compound e-Aluminium Alloy, edlala indima ekuconseni okusanhlamvu kwinqubo yokuncibilika nokusakaza, kepha umphumela mncane kunalokho kwe-titanium ne-zirconium. UVanadium futhi unomphumela wokucwengeka kabusha kwesakhiwo sokuphindaphinda futhi kwandise izinga lokushisa kabusha kabusha.

I-solubility eqinile ye-calcium e-aluminium alloy iphansi kakhulu, futhi yakha i-caal4 compact nge-aluminium. I-calcium nayo iyinto enhle kakhulu ye-aluminium alloy. I-Aluminium Alloy ene-5% calcium ne-5% manganese ine-superlulamity. I-calcium kanye ne-silicon form i-Casi, okuyi-insoluble e-aluminium. Njengoba inani lesisombululo esiqinile se-silicon sehlisiwe, ukuhanjiswa kwe-aluminium emsulwa yezimboni kungathuthukiswa kancane. I-calcium ingathuthukisa ukusebenza kokusika kwe-aluminium alloy. ICasi2 ayikwazi ukuqinisa ukwelashwa kokushisa kwe-aluminium alloy. I-Trace calcium inenzuzo ukususa i-hydrogen ku-aluminium ebiwe.

Ukuhola, i-Tin, kanye nezinto ze-bismuth kuyizinsimbi eziphansi ezincibilikisiwe. Bane-solubility encane eqinile e-aluminium, eyehlisa kancane amandla e-alloy, kepha ingathuthukisa ukusebenza kokusika. I-Bismuth inwebeka ngesikhathi sokuqina, okuzuzisa ukondla. Ukungeza i-Bismuth ku-High Magnesium Alloys kungavimbela i- "sodium brittleness".

I-antimony isetshenziswa ikakhulukazi njenge-modifier kuma-aluminium alloys, futhi akuvamile ukusetshenziswa kuma-aluminium alloys esetshenzisiwe. I-BUSPUTE kuphela BUSSITE E-AL-MG eyenziwe nge-aluminium alloys ukuvikela ukufona kwe-sodium. Lapho into ye-antimony ingezwe kuma-alloys athile we-al-zn-mg-cu-cucms, ukusebenza kokucindezela okushisayo nokucindezela okubandayo kungathuthukiswa.

I-Beryllium ingathuthukisa ukwakheka kwefilimu oxide ekwenziweni kwe-aluminium alloy futhi kunciphise ukulahleka okuvuthayo kanye nokuthambisa ngesikhathi sokuphonsa. I-Beryllium iyinto enobuthi engadala ubuthi bodwa. Ngakho-ke, ama-alloys we-aluminium ahlangana nokudla neziphuzo azikwazi ukuqukatha i-beryllium. Okuqukethwe kwe-beryllium ezintweni ezisetshenziswayo ze-welding kuvame ukulawulwa ngezansi kwe-8μ / ml. I-aluminium alloy esetshenziswe njengoba isisekelo se-welding kufanele futhi silawule okuqukethwe kwe-beryllium.

I-sodium icishe i-infoluble e-aluminium, i-solubility ephezulu eqinile ingaphansi kuka-0,0025%, futhi iphuzu le-sodium liphansi (97.8 ° C). Lapho i-sodium ikhona ku-alloy, i-adsorbed ebusweni bama-dendrites noma imingcele yokusanhlamvu ngesikhathi sokuqina. Ngesikhathi sokusebenza okushisayo, i-sodium emngceleni wokusanhlamvu kwakha ungqimba lwe-adsorption oluwuketshezi, futhi lapho ukwehla kwe-brittle kwenzeka, kwakhiwa i-naliali ye-sodium, futhi "i-sodium brittleness" ayiveli. Lapho okuqukethwe kwe-magnesium kudlula i-2%, i-magnesium izothatha i-silicon futhi iqonde i-sodium yamahhala, okuholela ku- "sodium embrittlement". Ngakho-ke, ama-alloys aphezulu we-magnoseum avunyelwe ukusebenzisa i-sodium usawoti fluxes. Indlela yokuvimbela i- "Sodium Embrittlement" yindlela ye-chlorination, eyenza i-sodium ihlele i-nacl futhi ihlukane ne-slag, futhi ingeza i-bismuth ukuyenza ikhiphe i-NA2BI bese ifaka i-matrix yensimbi; Ukungeza adrimony ukuze kwakhiwe i-NA3SB noma ukwengeza umhlaba ongavamile nakho kungadlala indima efanayo.
