connecting rods

[Alan]

I am doing a project on manufacture of connecting rods by casting, forging, powder metalugy and machining from solid. I would be very grateful for sources of technical info relating to properties required by conrods and how various forms of manufacture effect these.

Billet ! The hot rod boys catch word.

Billet is just a block of or some shape of material in raw form.
And of course it can be machined from it.
Some times the billet is forged, in it's rectangular shape, and sometimes it is forged in its semi con rod or what ever shape. The last is the strongest. And then it can be fully machined.
It becomes a toss up between strength and knotch sensitivity, as far as the material and hardness of it.
