Hmmmmmmm, but it's not going to hurt anyone for calcium to break down smaller.... Uhh, except teeth.... Hmmmmmm bones.....
Ok, google says this is the types of metals susceptible to Intergranular corrosion.
High-strength aluminium alloys such as the Duralumin-type alloys (Al-Cu) which depend upon precipitated phases for strengthening are susceptible to intergranular corrosion following sensitization at temperatures of about 120 °C. Nickel-rich alloys such as Inconel 600 and Incoloy 800 show similar.
How can we prevent intergranular corrosion?
Intergranular corrosion can be prevented through:
So we could limit it to anything that uses Aluminum or Nickel, as a bonding agent in the metal. Which is still most things, but it does eliminate things like bones, and pure, or mostly pure metals, like titanium (yay people can keep their replacement hips and skull plates) from being affected.
Most gold things are combined with nickel.
Steel is Iron combined with carbon, so would still be affected.
Ooo!, That means not all knives would be gone. Depending on what they're made from.
Gun metal, also known as red brass in the United States, is a type of bronze – an alloy of copper, tin, and zinc. Proportions vary but 88% copper, 8–10% tin, and 2–4% zinc is an approximation. Originally used chiefly for making guns, it has largely been replaced by steel.
Looks like most but not all guns would be gone.

How can we prevent intergranular corrosion?
Intergranular corrosion can be prevented through:
- Use low carbon (e.g. 304L, 316L) grade of stainless steels.
- Use stabilized grades alloyed with titanium (for example type 321) or niobium (for example type 347). Titanium and niobium are strong carbide- formers. ...
- Use post-weld heat treatment.
