    • The effect of heat treatment on the open circuit potential of magnesium sacrificial anode 

      A. M. H., Firdaus; Shaiful Rizam, Shamsudin; Shamsul Baharin, Jamaludin; M. N., Derman; Mohd Fitri, Mohd Wahid; M. Z., Ruhiyudin (University of Malaya, 2009)
      Magnesium sacrificial anode that possess high value of open circuit potential, Eoc is needed as it can protect larger area of underground metal structure in cathodic protection. Solution treatment was applied on magnesium ...

    • An electrochemical impedance spectroscopy study of Al-Zn and Al-Zn-Sn Alloys in tropical seawater 

      M. C., Isa; Abdul Razak, Daud; M. Y., Ahmad; M., Daud; Shaiful Rizam, Shamsudin; N., Hassanuddin; M. S., Din Yati; M. M., Muhammad (Trans Tech Publications, Switzerland, 2012)
      In this paper, a study on the electrochemical behaviour and electrical properties of Al-Zn and Al-Zn-Sn alloys in tropical seawater using open circuit potential (OCP) measurement and electrochemical impedance spectroscopy ...

    • Failure analysis on a ruptured petrochemical pipe 

      Mohd, Harun; Shaiful Rizam, Shamsudin; Azmi, Kamardin (Carl Hanser Verlag, 2010-03-16)
      The failure took place on a welded elbow pipe which exhibited a catastrophic transverse rupture. The failure was located on the welding HAZ region, parallel to the welding path. Branching cracks were detected at the ...

    • Microstructural study and differential scanning alorimetry analysis at elevated temperatures of uperheated as-cast A357 alloy 

      Mazlee, Mohd Noor; Shamsul, Baharin Jamaludin, Prof. Dr.; Kamarudin, Hussin, Brig. Jen. Dato' Prof. Dr.; Shaiful Rizam, Shamsudin (University of Malaya, 2009)
      The microstructure of superheated as-cast A357 alloy has been analysed to study the solidification structures of α-Al dendrites, eutectic Si particles and intermetallic compounds at different sections of the specimen. The ...

    • The root caused analysis of leakaged heat exchanger tube 

      Shaiful Rizam, Shamsudin; Mohd Arif Anuar, Mohd Salleh; Azmi, Rahmat, Assoc. Prof. Dr.; Mazlee, Mohd Noor, Dr.; Mohd Harun; Hafizal, Yazid (Carl Hanser Verlag GmbH & Co., 2015-03)
      AISI type 316L stainless steel was used as a heat exchanger tube material in an inter-cooler column. After less than a year of operation, severe corrosion failures occurred and a transverse opening leakage was observed on ...
