A Systematic Review on the Mechanical, Tribological, and Corrosion Properties of Al 7075 Metal Matrix Composites Fabricated through Stir Casting Process

Table 4

Comparative study of various manufacturing techniques of MMCs [21].

S. no.	Method	Range of size and shape	Advantages	Disadvantages
1	Stir casting	Larger size and extensive range	Low cost, less reinforcement damage, and very high metal yield (>90%)	Vol. fraction range up to 30%
2	Squeeze casting	Limited by preform shape, up to 2 cm height	Relatively expensive and volume fraction range up to 45%	Serious damage to reinforcement, meager metal yield
3	Powder metallurgy (PM)	Controlled size and a wide range	Very high metal yield and volume fraction range up to 30 to 70%	High-priced and reinforcement fracture
4	Spray casting	Larger size and limited shape	Metal yield is medium	High-priced
5	Infiltration process	Restricted size and limited by preform shape	Vol. fraction is more	High-priced
