flow occurs only in crystals riddled with defects

this sounds more like shearing - like slate or talc

It does. A sort of "super material" form of slate or talc.

<strong>Adrian Cho</strong><p>
<b>BALTIMORE, MARYLAND--</b>Since it was first reported that solid helium could flow without resistance, like a liquid devoid of viscosity, three other groups have reproduced the bizarre effect. But data presented here last week at an American Physical Society meeting also suggest that the "supersolid" flow occurs only in crystals riddled with defects.
