Microstructure investigations of in-situ copper tungsten carbide composite by mechanical alloying
(Universiti Malaysia Perlis, 2010-06-09)
An in-situ composite of copper and tungsten carbide powder was prepared by mechanical alloying of elemental powder. The sample has been milled in a high-energy ball mill for 20 h at different milling speed i.e. 100, 200, ...
Heating rate effects on properties of powder metallurgy Fe-Cr-Al2O3 composites
(Universiti Malaysia Perlis, 2010-06-09)
The aim of this study is to determine the optimum heating rate in fabricating Fe-Cr-Al2O3 composites by powder metallurgy methods. The Fe-based composites reinforced with ceramics are widely used due to their high strength, ...
Fabrication of titanium carbide reinforced copper matrix composite by in-situ processing
(Universiti Malaysia Perlis, 2010-06-09)
Composite materials with copper matrix and ceramic particle reinforcements provide an alternative material for scope for producing relatively high thermal conductivity, electrical conductivity and hardness properties. Most ...
Formation of TiC-reinforced iron based composite through carbothermal reduction of hematite and anatase
(Universiti Malaysia Perlis, 2010-06-09)
In this research carbothermal reduction of mechanical activated hematite (Fe2O3), anatase (TiO2) and graphite (C) was investigated. The mixtures of raw materials with composition of Fe-20vol%TiC were mechanically activated ...
