Abstract
Purpose: Objective of the paper was to determine the effect of particle size fraction for themechanical properties of powders and magnetic fields produced powder consisting of ironbasedalloys and an epoxy resin (trade name Epidian 100) which was obtained as a resultof press.Design/methodology/approach: Samples were produced by the method of singleunilateralpressing. To achieve the pursued objective, the following tests were performed:microstructural observations – light microscope, roughness tests, statistical the hysteresisloops.Findings: On the basis of the research it can be stated that with the increase in the sizefraction of the reinforcement of composites increased their roughness and greater was theirdensity. In addition, with the increase in the size fraction of the reinforcement of compositesincreased the field coercivity, while decreasing saturation magnetisation.Research limitations/implications: The study not specified time and the influenceof baling pressure on the mechanical properties and magnetic properties of compositesproduced using the single-uniaxial press.Practical implications: The division into three fractions powder using a sieve analysis didnot allow for adequate separation of powders. In each fraction were small particles. In thefuture, it will be used a long period of time sieving powders.Originality/value: The paper presents new method producing magnetic composites,where possible was give shape by using epoxy resin.

Purpose: Among many disciplines within engineering, welding is probably one of the most inexact – rather more of an art than a science. As weldment is meant the complete joint comprising the weld metal, heat affected zon...
