CrCoNi (an alloy of Chromoum-Cobalt-Nickel) is apparently the toughest alloy known surpassing even graphite; and since the only thing about adamantiun and vibranium that is really important is that they are the strongest metals in the fiction I would say that CrCoNi is the closest real world equivalent.
Cobalt-Chromium, or Cobalt-Chromium-Molybdenum are even used as artificial joints, heart valves, and dental implants because it’s so durable and corrosion resistant. They dropped Nickel from the alloy because it leached ions that aren’t good for humans.
Really close to the way adamantium is used in the comics.
