Mechanical Njirimara nke ọla

Mechanical Njirimara nke ọla-egosipụta ikike nke ihe na-egosi na iguzogide ibu metụtara ha. Ndị a ikike na-kwupụtara quantitative egosi. The n'ibu Njirimara nke ọla na alloys - bụ, na akpa ebe, na ike, ekweghị ekwe, ductility, ike. Ngwaahịa na-creep, eyi ndị na-eguzogide ndị ọzọ Njirimara.

Isi n'ibu e ji mara nke ihe kpebisiri ike site ọnwụnwa. Dabere na ọdịdị nke mmetụta nke ibu kwa unit nke oge, re-na-akwanyere ùgwù variables, ike na static ule. Mechanical Njirimara nke ọla na-egosipụta na mgbakwunye na isiokwu nke mpụga ibu. Karịsịa, ule ekenịmde mmetụta ekwe, torsion, mkpakọ, erughị ala na ndị ọzọ na mmetụta.

Mechanical Njirimara nke ọla-egosipụta n'oge deformation. N'okpuru a usoro ịghọta resizing na udi nke ngwaahịa n'okpuru nduzi nke nchegbu. Deformation nke siri ike ozu ekewa plastic na-agbanwe. Ke akpa idaha, ngwaahịa, mgbe mwepụ nke ibu na-adịghị eweghachi ya size na udi, na nke abụọ - na-abịa na ya mbụ ala tupu ngwa nke ike.

A, n'ibu Njirimara nke ọla-amalite na-akọwa na ekweghị ekwe. Na ọ bụ ihe kasị mkpa àgwà nke ngwaahịa. N'okpuru ekweghị ekwe ghọtara metal ike igosipụta iguzogide plastic deformation. Quantitative ọtụtụ nke ikike a bụ ihe kasị nkịtị na akara nke ngwaahịa mma.

The ọzọ dị mkpa mma bụ anwụ ngwa ngwa nke metal. N'okpuru a nghọta àgwà ngwaahịa ike iguzogide mgbaji ọkpụkpụ na deformation. Na mbibi nke usoro nke guzobere cracks, nke na-akpalite nkewa nke ihe onwunwe n'ime akụkụ. Ike index kpebisiri ike site na-eduzi tensile ule.

The ductility nke ihe e ji mara ya ike na-ata plastic deformation. Na ọzọ okwu, ọ na-ekpebi àgwà nke ga-ekwe omume nke mmapụta mgbanwe size na udi enweghị breakage. Plasticity bụ ihe dị mkpa ndabere maka nhọrọ nke ngwaahịa maka mgbali ọgwụgwọ.

The ike na-etinye obi ha dum akụkụ nke mpụga ike bụ n'ibu ume site plastic deformation a na-akpọ viscosity.

N'etiti alloys enyene a pụrụ iche n'ebe ígwè (ígwè-carbon alloy). O nwere 2,14% carbon bole na ụfọdụ adịghị. Iron-carbon alloy elu castability e ji mara.

The kasị ulo oru mmepụta ndị dị otú ahụ ụdị dị ka na-acha ọcha, isi awọ na ductile ígwè.

Akpa, n'ihi na ihe atụ, nwere elu ekweghị ekwe, ọ na-enye ndị na-eguzogide-eyi. Na nke a, na-acha ọcha nkedo ígwè bụ kenkuwa. Ke adianade do, ihe onwunwe na-gụrụ ọjọọ machining.

Dị ka otu n'ime ala foundry ụlọ ọrụ na-eji a na agba ntụ nkedo ígwè. Nke a ihe onwunwe nwere a ike ọdụdọ zuru ezu elu na-ọma-emeso.

Ntem, ductile ígwè mgbatị na a na-nyere na-ezi ahụ Njirimara.

Aluminum kwesịrị ekenyela n'etiti ndị na-abụghị ferrous ọla na alloys. Ha na-nyere na elu udu nke corrosion eguzogide, na-adị mfe doro machining na ịkpụzi.

Ọ bụkwa ezi ọsọ akụrụngwa na mmepụta nke ọla kọpa alloys na-ahụta. Ndị a mixtures nwere ezi eji, na nkà na ụzụ na nke anụ ahụ Njirimara.

Titanium alloys nwere nnukwu corrosion eguzogide, okpomọkụ na-eguzogide, elu ike. Ha na-ala njupụta.

Na- magnesium alloys, nke na-ọma gụrụ machining.
