Trying to find a desctiptive term

Email from a customer. He is trying to remember a word he heard about 12 years ago. “It was a new word that I had never heard of before, scientific sounding. He used it in a very similar way to, ‘carbide is a xxx metal, meaning that you can heat it up and then let it cool very slowly or very quickly and it will always be the same hardness’.”

One option:

xxx = Air hardening

Carbide, in the sense of a sintered WC composite, doesn't respond at all to heat treatment, I thought? Thus it's a non-hardening alloy, or even a "non-metal, refractory composite material" if he just wants some technobabble.

Not sure what he wants but he is a nice guy and he got me curious.

cermet?
Not sure what someone would call a material that is does not respond to heat treatment.
Though it does that because there are no phase or crystal structure changes.

heavy alloy, cermet, radiation shield are some of the names .As the material does not soften at 1000C or has low oxidation potential , the hardness remains unaffected.
