On VFR flight plan with student to GBN; talking to Luke Approach on 125.45 (com 1) Flight Service (com 2). On western heading at altitude of 4;500. Luke Approach informed us of possible traffic conflict '12 o'clock; 1 mile; 4;500; eastbound.' At that point IP took controls from student; reduced throttle and turned to right (north). Aircraft Y was observed passing overhead less than 300 feet. Aircraft Y was not communicating with Luke and on an east heading with an altitude of 4;500.
Near LUF; a PA-28 instructor pilot took evasive action from an aircraft which passed less than 300 feet overhead after Approach Control reported possible 4;500 feet traffic with which it was not communicating.
