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 influence of sintering temperature to the physical properties of P/M Co-Cr-Mo (F-75) alloy
(Universiti Malaysia Perlis, 2009-12-01)
Co-Cr-Mo (F-75) alloys are commonly used for surgical implants because of their strength, corrosion resistance and biocompatibility. Conventionally, fabrication of the alloys has been established using casting technique. ...
Effect of age hardening on Aluminum alloys: a study of motorcycle piston
(Universiti Malaysia Perlis, 2009-12-01)
