1. A method for connecting or joining a first substrate and a second substrate across an interface between the first substrate and the second substrate, the method comprising:
disposing a fastener precursor in a bore that extends into the first substrate and the second substrate; and
sintering, without shrinking the first and second substrates, the fastener precursor in the bore, wherein the fastener precursor densifies and shrinks in at least one dimension to mechanically interlock with a contour in the bore and form a mechanical fastener in the bore, and wherein the mechanical fastener forms an interlock between the first substrate and the second substrate.
