Mechanical ehupfumi chainge chakagadzirwa nesimbi

Mechanical ehupfumi chainge chakagadzirwa nesimbi dzinoratidza mano zvinhu kuratidza kuramba mitoro aishanda kwavari. nemano izvi varehwa quantitative zviratidzo. The zvemaziso zvivako chainge chakagadzirwa nesimbi uye alloys - ndiko, pakutanga, kuti kuoma, zvakaoma, ductility, simba. Products uyewo dzinobuda, kupfeka kuzvidzivirira uye vamwe zvivako.

The chikuru zvemaziso zvechadenga zvinhu kutsunga nemiedzo. Zvichienderana kwaitwa pamusoro mutoro chete chairema nguva, kuzodzosera vanokudzwa variables, aishingaira uye kunofambira mberi yokuedzwa. Mechanical ehupfumi chainge chakagadzirwa nesimbi vari kunoonekwawo mune mupanda kusvika nyaya nechitarisiko zvinorema. Zvikurukuru, miedzo kuitwa kwechirwere vachikotama, torsion, compression, kunetsana uye zvimwe zvinokonzerwa.

Mechanical ehupfumi chainge chakagadzirwa nesimbi hwakaratidzwa panguva deformation. Under izvi kunzwisisa resizing uye Maumbirwe chigadzirwa pasi pokudzora mupfungwa. Deformation miviri chikukutu rakakamurwa epurasitiki uye kwakavharwa nenyama. Muchiitiko chokutanga, chigadzirwa, pashure kubviswa mutoro haina ichadzorerwa yayo ukuru uye chimiro, uye yechipiri - anouya ayo hwepakutanga pamberi kushanda simba.

Kazhinji, asi zvemaziso ehupfumi chainge chakagadzirwa nesimbi vanotanga kurondedzera kuna pokuoma. Kuti kukosha risanyatsobuda. Under pokuoma ainzwisisa kugona simbi kuratidza kuramba epurasitiki deformation. Quantitative chiyero mano ichi ndicho iri kudzorwa chigadzirwa yepamusoro.

Inotevera chinokosha ndiko mukurumari yacho simbi. Under kunzwisisa unhu zvigadzirwa kugona ichi kurwisa kutsemuka uye deformation. Nokuparadzwa nedanho inotungamirwa makatsemuka, iyo chinokurwadzai kuparadzana kwemashoko napakati. Simba indekisi vagara vandifungira kuitisa tensile nemiedzo.

The ductility mashoko ndozvavava kukwanisa kwayo kuzosangana epurasitiki deformation. Mune mamwe manzwi, anosarudza kunaka mukana residual kuchinja pakukura namaumbirwo pasina breakage. Plasticity unokosha chokuratidza kuti kusarudzwa mishonga kuti dzvinyiriro kurapwa.

Kwaniso yekubata zvikamu kwokunze simba iri zvokuimba simba achishandisa epurasitiki deformation inonzi viscosity.

Pakati alloys anopindura rinokosha nzvimbo simbi (simbi-kabhoni chiwanikwa). Rine 2.14% kabhoni bole uye zvimwe netsvina. Iron-kabhoni chiwanikwa ane kumusoro castability unhu.

Rakajairika maindasitiri kugadzirwa vari mhuka dzakadai chena, bvudzi uye ductile simbi.

Chokutanga, Somuenzaniso, une yakakwirira zvakaoma, rine kuramba kupfeka. With ichi, chena kukandira simbi iri haungatani kuputsika. Uyezve, mashoko ari pachena kuti machine zvakaipa.

Somumwe pasi foundry indasitiri anoshandisa pfumbu kukandira simbi. Izvi zvinhu ane munhu tensile simba zvakakwana yakakwirira uye kwazvo zvakaipa.

Saizvozvowo, ductile simbi Kudzingwa uye rusununguko zvakanaka ehupfumi chaiko.

Aluminum inofanira dzinounzwa pakati asiri ferrous simbi uye alloys. Ivo rusununguko dzakakwirira prices ngura nemishonga, vari nyore pasi machine uye kurangwa.

Uyewo zvakajairika mazuva mbishi zvinhu zviri kugadzirwa alloys mhangura vanoonekwa. wemisanganiswa ava zvakanaka zvishoma nezvishoma mumatope, zviripo uye mumuviri zvivako.

Titanium alloys vane yakakwirira ngura nemishonga, kupisa nemishonga, mukuru simba. Vanodawo yakaderera arambe achirema.

Ko magnesium alloys, izvo zvakanaka pachena kuti machine.
