The effects of autocatalyst copper coating of SiCp on the microstructure of CuSiCp composites
(Universiti Malaysia Perlis, 2009-12-01)
In this paper, the autocatalyst copper coating (ACC) of silicon carbide particle
(SiCp) was performed after a sequence of surface treatment, sensitization and
surface activation processes. The ACC process was operated ...
The effects of solutionizing temperatures on microstructures of as-received A357 alloy
(Universiti malaysia Perlis, 2009-12-01)
Solution treatment has been carried out on as-received A357 alloy at two solution treatment temperatures of 530ºC and 550ºC for 11 hours. The microstructural study was performed by using optical microscope. Optical ...
The effects of welding current and welding duration on the shear strength of spot welded austenitic stainless steel
(Universiti Malaysia Perlis, 2009-12-01)
Introduction:
Resistance spot welding is commonly employed in the fabrication of sheet metal assembly. It can be applied to join metals such as low carbon steel, nickel, aluminum, titanium, copper alloy, stainless steel ...
Potentiodynamic polarization of Mg-0.22ca alloys containing minor element of Aluminium
(Universiti Malaysia Perlis, 2009-12-01)
Mg alloys played a significant role in replacing the existing sacrificial anodes. To maintain the negative potential and its capability in preventing corrosion, Ca and Al was added as alloying elements. Polarization curves ...
Microstructural study and differential scanning alorimetry analysis at elevated temperatures of uperheated as-cast A357 alloy
(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 ...
