METALLOGRAFIYa

METALLOGRAFIYa (az metall va … grafil), ilmest dar borai sokhti metallho va khulaho; qismi tarkibii metallshinosi. Metallografiya makrosokht va Mikrosokhti alyuminiy badi rekristallizasiya, ki bo yorii mikroskop dar rushnoii polirizasiyashuda mushohida karda shudaast (70 marotiba kalon karda shudaast).mikrosokhti metallhoro tahqiq karda (bo mushohidahoi bevosita yo bo yorii mikroskopho), qonuniyati tashakkuli sokhti metallu khulaho, inchunin vobasta ba tagyiryobii in sokht tagyir yoftani khususiyathoi mekhaniki, elektri, magniti, garmiguzaroni va dig. khosiyathoi fizikii onhoro meomuzad. Baroi omuzishi mikrosokht gayr az in, mikroskopiyai difraksnonii rentgeni istifoda meshavad (nig. Tahlili rentgenostrukturi).

Tashakkul va tagyiryobii sokhti dokhilii metallho dar natijai tagyirothoi fazavie, ki hangomi garm yo khunuk namudani metallho ruy medihand, inchunin dar natijai deformasiyai plastiki, shuogiri, rekristallizasiya va g. ba amal meoyad. Mas., afzudani surati khunukkuni boisi khurd shudani donahoi sokhti metall megardad. Andozai donahoi metallro bo deformasiyai plastiki va rekristallizasiya niz tagyir dodan mumkin ast.
