Thirty-two-year-old Hawley was a free agent after leaving Torquay United, while Igiehon recently had a spell with Swiss side FC Langenthal.
Both players have signed one-year deals with Alfreton, who are yet to register a point in the Conference Premier this season.
Neither player will make their debut against leaders Barnet on Saturday afternoon.
