How to unlock the Adamantium achievement in Marvel Avengers Battle for Earth - Definitive Guide
To elaborate a bit on Montana's solution, an adamantium grade is achieved when you score 4000 or more XP in a single fight. You are graded on your basic attacks, your super attacks, and your defense, which is pretty much how much damage you took.
Learn to chain super combos, learn to chain basic attacks into said super combos, and learn to dodge, and you'll eventually achieve this.

I received this on my second fight in story mode all I did after learning the basic controls after the first fight I tried to chain the moves together as quick as possible I did change characters multiple times don't know if that matters and I did take damage on both my characters if any one wants to add any more info all help is welcome
Adamantium is the highest possible grade you can earn in a match. The amount of XP needed is 4,000. You earn XP by doing basic moves, super moves, and you also earn xp based on how well you defend yourself. An easy way to earn this is to start a 2 player versus match and play by yourself. When the match starts, just string combo and tag combo super moves together and by the end of the match you should have earned enough for the achievement.
