while the preparation of sample by using powder metallurgy what factors are taken in consideration to finalize the percentage of the base material and reinforcements.
The first factor is the planned application and type of loading. Most commonly the powder metallurgy composites are intended as wear resistant materials. Therefore main factors will be hardness and fracture toughness which in their turn are determined by the hardness and fracture toughness of hard component as well as the ductility and wetting ability of the matrix metal. Also the structurally stable matrix should be selected properly to prevent pulling out the hard particles during wear
thanks a lot sir
so it means that in order to finalize the composition percentage of the matrix and the reinforcement the main important thing is the materials properties that we need in our application and on the basis of our application we will select the matrix, reinforcements and there percentage.
