Uburyo bwo gutoranya isahani ya titanium

Titanium alloy ni umusemburo ugizwe na titanium nibindi bintu. Titanium ifite ubwoko bubiri bwa kristu ya homogeneous na heterogeneous kristaliste: ipakiye hafi yimiterere ya mpande esheshatu munsi ya 882 ℃ α Titanium, umubiri wubatswe hagati ya 882 ℃ β Titanium. Noneho reka abo dukorana bo mu ishami ry’ikoranabuhanga rya RSM kugirango dusangire uburyo bwo gutoranya amasahani ya titanium

　　Ibisabwa bya tekiniki:

1. Ibigize imiti ya titanium alloy plaque igomba kubahiriza ibivugwa muri GB / T 3620.1, kandi gutandukana kwemewe kwimiti yimiti igomba kubahiriza ibivugwa muri GB / T 3620.2 mugihe Demander yongeye kugenzura.

2. Ikosa ryemewe ryububiko bwa plaque rigomba kubahiriza ibivugwa mu mbonerahamwe ya I.

3. Ikosa ryemewe ryubugari bwa plaque nuburebure bigomba kubahiriza ibivugwa mu mbonerahamwe ya II.

4. Buri mfuruka yisahani igomba gucibwa mu nguni iboneye uko bishoboka kwose, kandi gukata oblique ntibishobora kurenga gutandukana byemewe nuburebure nubugari bwisahani.

Ibintu bivanze bishobora kugabanywamo ibyiciro bitatu ukurikije ingaruka zabyo kubushyuhe bwo guhinduka:

Able Icyiciro α Icyiciro, ibintu byongera ubushyuhe bwinzibacyuho ni α Ibintu bihamye birimo aluminium, karubone, ogisijeni na azote. Aluminium nikintu nyamukuru kivanze na titanium alloy, igira ingaruka zigaragara mukuzamura imbaraga zumusemburo mubushyuhe bwicyumba nubushyuhe bwinshi, kugabanya uburemere bwihariye no kongera modulus ya elastique.

② Ihamye β Icyiciro, ibintu bigabanya ubushyuhe bwinzibacyuho ni β Ibintu bihamye birashobora kugabanywa muburyo bubiri: isomorphic na eutectoid. Ibicuruzwa bya Titanium bivangwa. Iyambere irimo molybdenum, niobium, vanadium, nibindi; Iyanyuma irimo chromium, manganese, umuringa, icyuma, silikoni, nibindi

Ibintu bidafite aho bibogamiye, nka zirconium na tin, bigira ingaruka nke kubushyuhe bwinzibacyuho.

Oxygene, azote, karubone na hydrogène ni umwanda nyamukuru muri titanium. Oxygene na azote muri α Hariho imbaraga nini zo gukomera mugice, gifite ingaruka zikomeye zo gukomera kuri titanium, ariko bigabanya plastike. Muri rusange hateganijwe ko ibirimo ogisijeni na azote muri titanium ari 0.15 ~ 0.2% na 0.04 ~ 0.05%. Hydrogen muri α Ubushyuhe bwo mu cyiciro ni buto cyane, kandi hydrogène nyinshi yashonga muri titanium alloy izabyara hydride, bigatuma amavuta avunika. Mubisanzwe, hydrogène iri muri titanium alloy igenzurwa munsi ya 0.015%. Iseswa rya hydrogène muri titanium irashobora guhinduka kandi irashobora gukurwaho na vacuum annealing.
