Experimental Study on Fatigue Behaviour of Shot-Peened Open-Hole Steel Plates
This paper presents an experimental study on the fatigue behaviour of shot-peened open-hole plates with Q345 steel. The beneficial effects induced by shot peening on the fatigue life improvement are highlighted. The characteristic fatigue crack initiation and propagation modes of open-hole details under fatigue loading are revealed. The surface hardening effect brought by the shot peening is an...
متن کاملShot Peening as an Alternative to Fatigue Life Improvement of CK45 Steel Coated with an Electroless Ni-Cu-P
The effect of an electroless Ni-Cu-P coating on the fatigue behavior of quenched and tempered CK45 steel has been investigated. The fatigue tests under rotating bending conditions have been conducted in three different conditions of uncoated, as-deposited and shot peened prior to the coating deposition. The results indicate that plating of the base steel leads to a fatigue life reduction. The d...
متن کاملRegression Analysis of Fatigue and Impact Strength of Shot Peened Welded Aisi 304 Austenitic
To upgrade the performance of welded joints the various improvement methods are used. Shot peening is one of the improvement method used to strengthen the properties of welded joints. GMAW process is very well suited for welding of AISI 304 austenitic stainless steels. Regression analysis is the statistical modeling technique, and it is suitable for the majority of predicting problems. It is va...
متن کامل3 - D analysis of fatigue crack behaviour in a shot peened steam turbine blade material
Serial mechanical sectioning and high resolution X-ray tomography have been used to study the three-dimensional morphology of small fatigue cracks growing in a 12 Cr tempered martensitic steam turbine blade material. A range of surface conditions has been studied, namely polished and shot peened (with varying levels of intensity). In the polished (unpeened) condition, inclusions (alumina and ma...
