Isahani ya Titanium
Ibisobanuro bigufi:
Titanium alloy ibyuma isahani ni umusemburo ugizwe na titanium nkibishingwe nibindi bintu byongeweho.Titanium ifite ubwoko bubiri bwa kristu ya homogeneous na heterogeneous kristal: imiterere yuzuye yuzuye ya mpandeshatu iri munsi ya 882 ℃ α Titanium, umubiri ushingiye kubic hejuru ya 882 ℃ β Titanium.
Titanium alloy ni umusemburo ugizwe na titanium nkibanze nibindi bintu byongeweho.Titanium ifite ubwoko bubiri bwa kristu ya homogeneous na heterogeneous kristal: imiterere yuzuye yuzuye ya mpandeshatu iri munsi ya 882 ℃ α Titanium, umubiri ushingiye kubic hejuru ya 882 ℃ β Titanium.
Ibintu bivanze bishobora gushyirwa mubyiciro bitatu ukurikije ingaruka zabyo kubushyuhe bwinzibacyuho:
① Ihamye α Ibintu byongera ubushyuhe bwinzibacyuho ni α Ibintu bihamye birimo aluminium, karubone, ogisijeni, na azote.Aluminium ningingo nyamukuru ivanga titanium alloy, igira ingaruka zikomeye mukuzamura ubushyuhe bwicyumba nubushyuhe bwo hejuru bwubushyuhe, kugabanya uburemere bwihariye, no kongera modulus ya elastique.
Able Ihamye β Ibintu bigabanya ubushyuhe bwinzibacyuho ni β Ibintu bihamye birashobora kugabanywa muburyo bubiri: isomorphic na eutectoid.Ibicuruzwa bikoresha titanium alloy Iyambere irimo molybdenum, niobium, vanadium, nibindi;Iyanyuma irimo chromium, manganese, umuringa, icyuma, silikoni, nibindi
Ements Ibintu bidafite aho bibogamiye nka zirconium na tin nta ngaruka nini bigira ku bushyuhe bwinzibacyuho. Oxygene, azote, karubone, na hydrogène ni umwanda nyamukuru muri titanium.Oxygene na azote muri α Hariho imbaraga nyinshi mu cyiciro, bigira ingaruka zikomeye ku mavuta ya titanium, ariko bigabanya plastike.Umwuka wa ogisijeni na azote muri titanium usanzwe ugaragara ko uri munsi ya 0.15 ~ 0.2% na 0.04 ~ 0.05%.Hydrogene muri α Ubushyuhe bwo mu cyiciro buri hasi cyane, kandi hydrogène ikabije yashonga muri titanium alloys irashobora kubyara hydride, bigatuma amavuta avunika.Hydrogene iri muri titanium isanzwe igenzurwa munsi ya 0.015%.Iseswa rya hydrogène muri titanium irashobora guhinduka kandi irashobora gukurwaho na vacuum annealing.
