Both exercises work the biceps and to a lesser extent the forearms (through static contraction) but the hammer curls also work the brachialis - an oval shaped muscle that you can see between the biceps and triceps when looking at the arm side-on (look at a pic of a bodybuilder and you'll see what I mean)
