To use it as an adjective, you should add '-ed' to the end and use a hyphen, making it 'iron-willed.' For example, you would say 'She is an iron-willed leader' rather than 'She is an iron will leader,' which sounds grammatically incorrect to native ears.

In this context, 'will' refers to your desire, purpose, or determination to do something specific. It is the same root as the helping verb 'will' (as in 'I will go'), but here it functions as a noun representing your internal drive and mental power.
