Abstract
A solid-state material processing method called friction stir processing (FSP) is primarily utilized to enhance mechanical characteristics, eliminate casting defects, and refine grains. In present study FSP parameters namely tool rotational speeds (560, 710, and 900 rpm) and tool tilt angles (0° and 1.5°) have been investigated for microstructural refinement of Mg-2Zn Mg-alloy. The traverse speed kept constant at 25 mm-min-1. The results showed that the FSP performed at low tool rotational speed of 560 and 710 rpm in combination 0° tilt angle yielded structural defects, whereas rotation speed of 900 rpm and tilt angle 1.5° resulted into defect free microstructure and significant grain refinement from 63.86 µm to 27.38 µm, and microhardness improvement from 47 HV to 58 HV. The electrochemical corrosion resistance of FSP processed Mg-2Zn Mg-alloy was deteriorated as compared with the as-rolled Mg-2Zn Mg-alloy after 24 hrs.
