Hulk has demonstrated such feats. there are scans in this forum showing that too.
my point with the magneto comparison was that the power to do such things resided well within the physical world (Magneto's realm), thus within Hulk's capabilities.
think about it, does Hulk need to touch the molecules to actually violently separate them from one another?
of course not, he just pulls hard enough at both ends of a limb and the adamantium starts to register that extraordinary energy at the molecular level.
there's really no other option here. if it's physical, it can be done in an inefficient (Hulk strength converted by the adamantium medium to molecular level) or efficient (Magneto's direct application on the molecular level) means.
your missing the point and trying to use real world logic which means nothing is the comic world. Adamatium can not be physically damaged. Hulk can not damage, because adamatium can not be damage. Magneto using his powers over metal can transmute the adamatium into anther state of being. He not using physical force for this to happen. Adamatium can not be damage by any type of physical force it can only be transmuted and altered at molecular levels in which hulk has no way of doing.
even setting aside logic (real world or otherwise), given that this is comic book pseudo-science, the adamantium is likely not indestructible.
perhaps Hulk gives Wolverine such a furious beating that the friction and mass of Hulk's fist hitting against him causes his body to heat and the adamantium to melt?
more likely, a caption comes up saying, something along the lines of the following: "and yet the green behemoth persists, unrelenting, unstoppable and immune to the knowledge of adamantium's indestructibility.. and, as Wolverine begins to discover, even adamantium yields to the awesome force of The Hulk" ... the next page showing a Wolverine-sized pretzel.
seriously, Hulk would be well within his "rights" to be able to do something like that. it would actually surprise me if he couldn't do that on account of adamantium's "indestructibility".
It is indestructiable. Hulkd can't break it. Hulk has failed to do so on 14 occassions. people more powerfulk then hulk such as Ba'al failed to do so eve when trying to. Melt? It been in the sun and was undamage as well as taking a nuke and being fine. Hulkd can't break it. It is comic fact well in 616 at least
think we're just gonna have to disagree on this. I see it as part of Hulk's heritage that he breaks what can't be broke. that added to logic basically.
anyway, it's beside the point as Hulk could simply pull the adamantium skeleton out of Wolverine. one quick yank on those retractable claws and it's done.
