Zlítina (tudi zlitína) ali legúra je trdna raztopina dveh ali več kovin. Dobimo jih, če osnovni kovini dodamo enega ali več zlitinskih (legirnih) elementov. Z legiranjem (ustvarjanjem zlitin) izboljšujemo lastnosti osnovnim kovinam. Predvsem dosegamo optimalne lastnosti, kajti ni takega elementa, ki bi spremenil lastnosti osnovne kovine po naših željah. Zlitine lahko delimo glede na količino zlitinskih elementov na:

  • mikrolegirane,
  • malolegirane in
  • močno legirane.

Pri majhnem dodatku zlitinskega elementa se njegovi atomi vgradijo v kristalno mrežo osnovne kovine. Če so precej manjši, se vrinejo na prazna mesta med atomi, ki jih imenujemo vrzeli ali intersticije; če so podobne velikosti ali večji kot atomi osnove, pa zamenjajo ali substituirajo atome osnove na mrežnih mestih. Nastanejo zmesi atomov v trdnem stanju - trdne raztopine, ki so lahko intersticijske in substitucijske. Nekateri elementi so povsem mešljivi v trdnem stanju (npr. Cu-Ni). Ti se podobno kot voda in alkohol mešajo v poljubnih razmerjih.

Kadar dodatek zlitinskega elementa preseže topnost v osnovni kovini, se iz trdne raztopine izloči druga snov - faza. Ta faza je lahko trdna raztopina dodanega elementa, spojina med kovinskimi elementi (intermetalna spojina) ali kakšna druga spojina (karbid, borid, ...).

Pri večjih dodatkih zlitinskega elementa lahko nastopajo številne reakcije pri prehodu iz tekočega v trdno agregatno stanje, kakor tudi reakcije v trdnem stanju. Kaj se bo zgodilo, lahko razberemo iz ustreznega faznega diagrama.

Po namenu uporabe ločimo : ležajne zlitine - zlitine s kositrom, antimonom, svincem, bakrom , ... (gl. JUS C.E1.100) imenovane tudi bele ležajne kovine, med njimi so najzanimivejše zlitine za drsne ležaje (kositrovi in svičevi broni, rdeča litina in nekatere medi)

[uredi] Primeri zlitin

  • alpaka - zlitina bakra, cinka in niklja
  • amalgam - zlitina živega srebra in natrija
  • babbit
  • bron - zlitina bakra in drugih kovin
  • cekas - zlitina železa, niklja in kroma* stelit - zlitina kobalta, kroma in volframa
  • duraluminij - zlitina aluminija, bakra in magnezija
  • elektron - zlitina zlata in srebra
  • invar - zlitina železa in niklja
  • jeklo - zlitina železa, ogljika in drugih kovin
  • medenina (tudi med) - zlitina bakra in cinka
  • silumin - zlitina silicija in aluminija
  • vidia - zelo trda zlitina volframovega karbida, kobalta in titana (to v pravem pomenu ni zlitina, temveč je kompozit sestavljen iz volframovega karbida, ki je nosilec trdote, ter žilave osnove - kobalta, ki delce WC povezuje v celoto. Ta material navadno imenujemo karbidna trdina; termin vidia izhaja iz nemščine: wie diamant = kot diamant /trd namreč/). Karbidne trdine izdelujemo s postopki prašne metalurgije.

Легура је смеса два или више елемената од којих је барем један метал. Легирајући елементи могу да са основним металом формирају једну фазу, тзв. чврсти раствор (једнофазне легуре) или више различитих фаза (вишефазни системи). Особине једнофазних легура зависе углавном од хемијског састава тј. удела легирајућег елемента, док код вишефазних легура облик, величина и расподела различитих фаза микроструктура играју одлучујућу улогу.

Легура има особине метала али оне могу бити знатно различите од особина чистих компонената из којих се легура састоји. Особине легура се могу променити односно побољшати механичком или термичком обрадом, као нпр. ваљањем, ковањем, жарењем, каљењем или отпуштањем.

Legering (av legera, av lat. li´go 'binda ihop', 'förena'), material med metalliska egenskaper vilket består av två eller flera grundämnen (legeringskomponenter), varav minst ett är metall. Även en blandning av två eller flera polymera material kan ibland också kallas för legering.

En metallegering består oftast av en baskomponent (till exempel aluminium, bly, järn, koppar eller tenn). Till baskomponenten sätts sedan ett eller flera legeringselement (legeringsämnen) som kan vara såväl metaller som icke-metaller. Legeringar framställs vanligen genom att de olika komponenterna i form av smältor blandas. Legeringar kan dock även framställas genom till exempel pressning och sintring av pulverformiga ämnen, eller genom mekanisk bearbetning av material. Ofta räcker ganska små mängder tillsatsämnen, eller mindre variationer på proportionerna av ingående ämnen, för att ge stora ändringar på egenskaperna för den färdiga legeringen.

Legeringar har mycket stor teknisk betydelse och har använts av människan i tusentals år (t.ex. brons). I konstruktionssammanhang används så gott som alltid metaller i form av legeringar. Rena metaller är vanligtvis för mjuka och saknar styrkan för att kunna användas i praktiskt bruk. I en legering kan däremot både hårdheten och styrkan hos metaller ökas, dessutom kan saker som korrosionsbeständighet och gjutbarhet samt elektriska och magnetiska egenskaper också påverkas. Som exempel kan man ta rosttrögt stål, ofta oegentligt kallat rostfritt stål. Man tillför där krom till en järn-nickellegering och därigenom minskar korrosionsangreppen vid vatten- och luftkontakt.

En tekniskt viktig grupp är systemet tenn/bly (se lödning.) Den tas här som exempel på vad som händer när halterna av basämnena varieras. Tekniskt rent bly har smältpunkten 327 °C och tenn smältpunkten 234 °C. Dessa metaller är ömsesidigt lösbara i varandra. Om temperaturen är tillräckligt hög smälter såväl blyet som tennet. Tillsättes mer av det ena ämnet så löses det i det andra intill en viss gräns, då lösningen blivit mättad. I ett visst läge råder balans, då bägge ämnena innehåller en mättad lösning av den andra. Detta är den s k eutektiska blandningen. Därvid har man också kommit till systemets lägsta smälttemperatur. Tabellen nedan illustrerar förloppet.

จากวิกิพีเดีย สารานุกรมเสรี

โลหะผสม หรือ อัลลอย (อังกฤษ: alloy) คือวัสดุที่เกิดจากการรวมกันของโลหะตั้งแต่ 2 ชนิดขึ้นไป โดยวัสดุโลหะผสมที่ได้จะมีคุณสมบัติแตกต่างจากส่วนประกอบเดิมของมัน

โลหะผสมถ้าเกิดจากโลหะ 2 ชนิด เรียกว่า ไบนารี่อัลลอย (binary alloy), 3 ชนิด เรียกว่า เทอร์นารี่อัลลอย (ternary alloy), 4 ชนิด เรียกว่า ควอเทอร์นารี่อัลลอย (quaternary alloy)

ตามธรรมดาโลหะผสมจะถูกออกแบบให้มีคุณสมบัติที่ต้องการมากกว่าการดูที่ส่วนผสมของมัน ตัวอย่างเช่น เหล็กกล้าจะแข็งแรงกว่าเหล็กซึ่งเป็นธาตุเหล็ก ทองเหลืองจะมีความทนทานมากกว่าทองแดง แต่มีความสวยงามน่าดึงดูดใจมากกว่าสังกะสี

ต่างจากโลหะบริสุทธิ์ โลหะผสมหลายชนิดไม่ได้มีจุดหลอมเหลวจุดเดียว มันจะมีช่วงหลอมเหลวแทน ซึ่งในวัสดุจะเป็นของผสมระหว่างเฟสของแข็งและของเหลว อุณหภูมิที่ซึ่งการหลอมเหลวเริ่มเรียกว่า โซลิดัส (solidus) และอุณหภูมิที่ซึ่งการหลอมเหลวหมดเรียกว่า ลิควิดัส (liquidus) โลหะผสมพิเศษสามารถจะออกแบบให้มีจุดหลอมเหลวเดียวได้ ซึ่งเรียกโลหะผสมนี้ว่า ยูทีติกมิกซ์เจอร์ (eutectic mixture)

บางครั้งโลหะผสมตั้งชื่อตามโลหะพื้นฐาน เช่น ทอง 14 เค หรือ 14 การัต (58%) ทองคำ คือโลหะผสมที่มีทองอยู่ 58 % ที่เหลือเป็นโลหะอื่น เช่นเดียวกับ เงิน ใช้ในเพชร (jewellery) และอะลูมิเนียม

โลหะผสมมีดังนี้:

Alaşım, bir metal elementin başka metaller ya da herhangi başka elementler ile homojen karışımıdır. Alaşımlar karışımdaki metallerin özelliklerinden farklı özellikler gösterirler. En bilinen alaşımlara; tunç (bakır-kalay), pirinç (bakır-çinko), lehim (kalay-kurşun) ve cıva alaşımları olan amalgamlar örnek verilebilir. Alaşımlar, uygulamaların gerektirdiği fiziksel özelliklere sahip malzemeler üretilmesinde yaygın olarak kullanılır.

Tarihçe [değiştir]

Tunç Çağı'ndan kalma çeşitli tunç aletler

Tunç Çağı'ndan kalma çeşitli tunç aletler

Alaşımların tarihi milattan önce 4. bin yıllara kadar uzanmaktadır. İran ve Mezopotamya bölgelerinde bulunan tunç (bronz) örnekleri bu zaman diliminde tarihlenmiştir.[1] Demirden daha sert olan tunç; silah, kesici ve delici aletler, mutfak aletleri, süs eşyaları vb. yapımında günümüze değin kullanılagelmiştir.

Yapılan arkeolojik çalışmalarda Çin'in Sincan bölgesinde M.Ö. 1000 yıllarına[2] ve Hindistan'ın Merkez Ganj Vadisi ve Doğu Vindhyas bölgesinde M.Ö. 1800 yıllarına[3] tarihlenen çelik buluntulara rastlanmıştır. Sözkonusu buluntular çelik kullanımının en az 3000 yıllık bir tarihinin olduğunu belgelemektedir. Tunça göre daha sert ve dayanıklı olan demir-karbon alaşımı çelik çeşitli araç gereç yapımında yaygın olarak kullanılmıştır.

Alaşımların Üretim ve Kullanımı [değiştir]

Alaşım üretiminde çeşitli yöntemler kullanılır. Ergitme sureti ile karıştırma, mikroskopik boyutlarda toz karışımların yüksek basınç altında preslenerek sinterlenmesi (yüksek sıcaklıklarda ısıtma) bunlardan bazılarıdır. Cıva elementinin birçok metal ile kolayca amalgam oluşturabilme özelliği de alaşım üretiminde kullanılır.

Alaşımlar, uygulamaların gerektirdiği fiziksel özelliklere sahip malzemelerin üretilmesini sağlar. Yüksek sıcaklıklar, aşınma, kimyasal etkiler, metal yorgunluğu vb. gibi her türlü etkilere saf metallerin yetersiz kaldığı durumlarda, gerekli olan özellikleri sağlayan niteliklerde alaşımlar kullanılır. Örneğin demirin sertliğinin yeterli olmadığı uygulamalarda, daha sert yapıdaki demir alaşımları olan çelikler kullanılır.
