I thought reforming the bonds of microfractures was already well known as a differentiator between metalloids and true metals? So does this mean that metalloids just shouldn't be a group anymore, or that they instead have to be expanded to include more materials? And certain substitutional alloys can be argued to be self healing. In bronze the copper will replace any displaced tin and zinc bonds without heat, for example.
