Sei kubviswa kwekusarira kunetseka kuchidiwa kune aruminiyamu alloys?

Munguva yekugadzirwa kwealuminium alloys (kukunguruka, extrusion, machining, welding uye quenching), kushushikana kwakasara kunozoitika mukati mezvinhu-izvi zvinoita sekushushikana kusingaoneki kwakavharirwa mukati mesimbi. Kana isina kubviswa panguva yakakodzera, inokonzeresa deformation yechikamu, dimensional kushivirira kunze-kwe-kutsanangurwa, kuputika, uye kunyange kuderedza kushomeka kwekupokana kwealuminium profil.

Kurapwa kwekushushikana kwekushushikana kunomira senzira yakakosha yekuvimbisa kunaka kwezvigadzirwa zvealuminium alloy, ingave yemazuva ese-kushandisa aruminiyamu profiles hwindo nemusuwo, michina inogadzirwa kubva kuIndustrial aluminium profile kana yakakwirira-yekupedzisira aerospace zvikamu zvechimiro. Chaizvoizvo, kusara kwekushushikana kunobva kubva mukusaenzana kwenzvimbo deformation kana kukurumidza kushanduka tembiricha panguva yekugadziriswa kwealuminium alloy, izvo zvinodzivirira aluminium extrusion profile kubva kuzere kusimuka kudzokera kune yavo yekutanga chimiro.

Residual stress inonyanya kukonzerwa nezvinhu zvitatu zvakajairika:

Kutanga, kusaenzana kwemamiriro ekupisa. Localized kupisa kwakanyanya uye kukurumidza kutonhora panguva yekudzima mhinduro (yakagamuchirwa zvakanyanya kune yakakwirira-simba aruminiyamu alloys) uye welding inogadzira isingaenderane yekupisa contraction mukati mechinhu.

Chechipiri, plastiki deformation. Simba rekunze rinoshandiswa panguva yeextrusion, kukunguruka uye kutonhora kushanda kunoburitsa madhigirii asina kuenzana e deformation pakati pepamusoro nemukati mezvikamu, zvichisiya kushushikana kutadza kuburitswa zvizere.

Chechitatu, kugadzirwa kwemichina. Kucheka mashandiro akadai sekugaya uye kuchera kunobvisa zvinhu kubva pachikamu chepamusoro, kukanganisa mukati mekushushikana kuenzana uye kukonzeresa kusara kunetseka.
