13. A downhole tubular assembly, comprising:
an outer tubular member including a through bore defined by an inner diameter (ID);
an inner tubular member comprising an outer diameter (OD) moveable into the ID of the outer tubular member;
a swellable metallic material carried on the ID of the outer tubular member or the OD of the inner tubular member;
a cover initially covering the swellable metallic material, wherein the cover is opened in response to moving the OD of the inner tubular member into the ID of the outer tubular member to expose the swellable metallic material to an activation fluid,
wherein the swellable metallic material is swellable into locking engagement with the ID of the outer tubular member and the OD of the inner tubular member in response to exposure to the activation fluid to secure the outer tubular member to the inner tubular member, and wherein the outer tubular member comprises a polished bore receptacle defining the ID;
a seal assembly disposed on the OD of the inner tubular member for sealing engagement with the ID of the polished bore receptacle; and
a ratchet-latching mechanism for securing the outer tubular member to the inner tubular member, wherein the swellable metallic material increases a tensile rating of the ratchet-latching mechanism.
