摘要
Abstract
The paper investigates the effect of main parameters on particle distribution in centrifugally cast magnesium matrix composites using theoretical and experimental studies.The study aims to depict solidification impacts on particle movement,along with other main forces.The findings demonstrate that the rotation speed,solidification interval,and density differential between the matrix and particles affect the thickness of the particle-segregated zone caused centrifugal force.Additionally,the comparison of SiCp distribution in the AZ91 matrix composite between the theoretical model and experiments shows that the proposed analysis is acceptable at 10%(in weight)at the middle zone.The difference between the experimental and theoretical results is 5.83%,10.20%,and 4.86%in the outer region and 2.64%,1.58%,and 2.36%in the middle region for each of 5%,10%,and 15%(in weight)composites,respectively.关键词
