Material Science: Types of Defects in Atomic and Ionic Structures, Essays (university) of Material Science and Technology

Erciyes UniversityMaterial Science and Technology

An overview of three types of defects in atomic and ionic structures: point defects, line defects (dislocations), and surface defects. It also discusses the causes and effects of various types of defects, including the impact of material properties. Defects are classified based on their dimensions: point defects, line defects, and three-dimensional defects.

MALZEME BİLİMİ

Atomik ve İyonik Düzenlerde

Hatalar

Hedefler

  1. 3 temel hatayı tanımlamak:
  • Noktasal Hatalar
  • Çizgisel Hatalar (dislokasyonlar)
  • Yüzey Hataları
  1. Değişik tür hataların neden ve etkilerini araştırmak,
  • Gerçekte kristaller hiçbir zaman kusursuz değildir, alaşımlar da soğuk şekillendirilebilirlik, yarı iletkenlerde elektrik iletkenliği, atomların hareket hızı ve metallerde korozyon gibi bir çok fiziksel ve mekanik özelliği etkileyen kusur içeriler.
  • Kusurların malzeme özelliklerine büyük etkisi vardır.
  • Kristal kafes kusurları geometrilerine ve şekillerine göre sınıflandırılabilir;
    1. Bir boyutlu (nokta kusurları)
    1. İki boyutlu çizgi kusurları (Dislokasyonlar)
    1. Üç boyutlu kusurları (yüzeyler ve tane sınırları)
