Abstract

Shot peening is used for creation of compressive residual stresses on the surface layers of components and thus improving their performance. In this work, residual stresses in shot peened AISI 1020 steel were measured by using electro-chemical layer removal technique and strain gauges. Relations between Almen intensities, obtained by shot peening under various conditions, and residual stresses were investigated. Residual stresses in the steel in rolled and in annealed conditions were compared. Maximum residual stresses created in the steel by shot peening varied between 276 MPa (compression) to 363 MPa (compression).

Özet

Bilyeli dövme, metal parçaların yüzeylerinde basma kalıcı gerilmeleri oluşturarak performanslarını geliştirmek için kullanılan bir metottur. Bu çalışmada bilyeli dövülmüş Ç1020 çelik numunedeki kalıcı gerilme değerleri, elektro-kimyasal katman kaldırma tekniği ve gerinim ölçerler kullanılarak incelenmiştir. Farklı şartlarda bilyeli dövülerek elde edilen çeşitli Almen şiddetleri ile kalıcı gerilmeler arasındaki ilişki araştırılmıştır. Çelik malzemede hadde halinde ve tavlanmış halinde oluşan kalıcı gerilmeler karşılaştırılmıştır. Bilyeli dövme ile çelikte oluşturulan maksimum kalıcı gerilmelerin 276 MPa (basma) ile 363 MPa (basma) arasında değiştiği görülmüştür.
