EFFECT OF SCANDIUM ADDITION ON THE EROSION CORROSION BEHAVIOUR OF AA7075

تاثیر اضافه کردن اسکاندیوم بر رفتار خوردگی سایشی آلیاژ AA7075 آلومینیوم-0.2wt.% Scandium  has  been added  to  the  7075  aluminium  alloy  through  stir casting  technique  to  obtain  10  mm  thick  plates. using Taguchi’s orthogonal arrays ...

Failure Pressure Analysis of Corroded Pipelines with Spherical Corrosion Pit

تحلیل فشار شکست خطوط لوله خورده شده با خوردگی حفره ای کروی-Corrosion pits were investigated by finite element method. Effects of internal pressure, radius, depth and spacing of corrosion pits on failure pressure of corroded pipeline were discussed. The results show that failure pressure of corroded pipeline with spherical corrosion pit obtained by FEM is bigger than by ASME B31G . ...

Monitoring of the External Corrosion of Buried Pipelines

پایش خوردگی بیرونی خطوط لوله دفنی-The methods for the monitoring of various types of external corrosion of underground pipelines are investigated. The various scenarios where electrical resistance soil corrosion probes can be used for corrosion damage assessment or for the control of cathodic protection effectiveness are described. The possibilities of using hydrogen probes for the prediction of stress corrosion cracking of pipelines are discussed. ...
