Hi guys,
1st year mech engineering student looking to get some input on a recent project for my Material Selection class
I have to select an alternative material that could be used to make a car piston
For simplicity I'll only be forcusing on the piston itself, not the con rods or anything like piston rings
I have done some research and most car engines for public use are made from silicone aluminum alloy. The properties are light weight, easy to machine, available material and can be forged to increse strength
I've thought about suggesting a Titanium piston. Advantage would be less thermal expansion than aluminium, higher melting point ... Disadvantage would be cost to procure and it's harder to machine than aluminum.
As long as I pick a material of similar properties as what is currently used I'll be fine.
Does anyone have more innovative ideas? I think most of my class will be choosing titanium. as long as I state the positive and negative sides to the selected material, the answer is acceptable.
thanks for reading.
