Tafura 3 Riveting kutaridzika kwemasampuli 1 kusvika 3 pasi pemaviri maitiro masisitimu
Mhedzisiro yezviyo morphology uye kuchembera mamiriro pane axial compression cracking maitiro emaprofiles akadzidzwa. Kushushikana kwemamiriro ezvinhu panguva yeaxial compression yaienderana neiyo yekuzviboora riveting. Chidzidzo chacho chakawana kuti kuputika kwakabva kumiganhu yezviyo, uye nzira yekuputika yeAl-Mg-Si alloy yakatsanangurwa nemaitiro.
σapp ndiko kushushikana kunoshandiswa kune kristaro. Pakutsemuka, σapp yakaenzana neiyo chaiyo yekushushikana kukosha inoenderana nesimba rekusimba; σa0 ndiko kushorwa kweiyo precipitates panguva intracrystalline sliding; Φ ndiyo dhizaini yekumanikidza, iyo ine hukama nehukuru hwezviyo d uye slip hupamhi p.
Kuenzaniswa nerecrystallization, fibrous zviyo chimiro chinonyatso batsira pakupwanya inhibition. Chikonzero chikuru ndechekuti chiyero chezviyo d chakanyanya kuderedzwa nekuda kwekunatswa kwezviyo, izvo zvinogona kunyatsodzikisa kushushikana kwekushushikana Φ pamuganhu wezviyo, nokudaro zvichidzivisa kuputika. Kuenzaniswa nefibrous structure, iyo stress concentration factor Φ ye recrystallized alloy ine coarse grains inenge 10 times that of the first.
Kuenzaniswa nekuchembera kwepamusoro, iyo yakanyanya kuchembera nyika inonyanya kukonzeresa kupaza inhibition, iyo inotemerwa nenzvimbo dzakasiyana dzekunaya kwemvura mukati meiyo alloy. Munguva yekukwegura kwepamusoro, 20-50 nm 'β (Mg5Si6) zvikamu zvakasvibiswa mu 6082 alloy, ine nhamba yakawanda yemvura uye zviduku zvishoma; apo alloy iri mukukwegura-kukwegura, nhamba yemvura mu alloy inoderera uye ukuru hunova hukuru. Iyo precipitates inogadzirwa panguva yekuchembera inogona kunyatso kuvharira kufamba kweiyo dislocation mukati meiyo alloy.
