? 2022 Elsevier LtdMetal matrix composites are an important class of materials owing to their excellent mechanical properties. The strengthening mechanisms of the composites are mainly determined by the volume fraction of the reinforcement particles. Surface composite is a category of metal matrix composites that can be easily fabricated by friction stir processing in which reinforcement particles are limited to the surface. Determination of the volume fraction is a complicated task due to the incorporation of the reinforcement particles only in the surface layer. There is no established procedure to measure the volume fraction of the reinforcement particles in the surface composites. A discrepancy of about 10–30% is reported in various volume fraction determination procedures. Investigators used various approaches to estimate the volume fraction of the surface composites. These approaches are discussed in brief with the methodology adapted and corrections for accurate estimation are also provided.
