Hey guys, a while ago I asked how powdered metallurgy works and
received some great replies.
I read that when p/m engine connecting rods are made, the big end is
fractured instead of cut like drop-forged rods. That got me wondering
how p/m rods would fail compared to forged rods. Do they bend like
forged rods when failing in compression? How about when the big end
falls apart from being over-revved, under-lubricated, etc.?
I also looked at some pictures of forged and p/m rods. The p/m rods
use blind bolts and most of the OE-style forged rods use a nut and
bolt. Why is that?
TIA as always for the education.
