A titanium part can pass its chemistry cert and still fail because of alpha case – a thin, brittle oxygen-enriched skin from hot work. What it is, why it matters, how to remove it.

Two real Ti-6Al-4V heats, side by side: the chemistry varies between melts but both are Grade 5. Why that happens, when it matters, and how to specify around it.

Titanium machining trouble is physics, not luck: heat trapped at the edge, adhesion to tooling, and a work-hardening loop. Here is why, and how the bar you start with changes it.

A receiving-inspector’s walk through a real Ti-6Al-4V (TC4) ingot test report, what the top/bottom chemistry, interstitials and test methods actually tell you.
