Yikes! Fork failure is the stuff of nightmares. I'm glad you're okay.
Among the participants of a local riding club in my area, I've met two people with custom titanium frame builds who told me that their frames cracked within a few years of use.
Still have nightmares about a fork that, during a mountain bike descent 30 years ago, started oscillating increasingly until it bent and locked the wheel perpendicular to my vector - and my buddy still has dreams of me acting Superman along his ride, for a few short instants...
Titanium can have problems with oils I've been told. Seeping into crystal defects and propagating. Typically I've been told they use polymer coatings to prevent the ingress. But with scratches and lubricants I think this would be much more common if it was a real thing.
I've always thought a spring bronze/brass frame would be fun. Even better modulus of elasticity, but the strength to weight is much worse.
