The Development of New Materials and Modes of Casting Metal Powder Mixtures (MIM Technology)

Abstract:

Article Preview

In the present work, to reduce the cost of production of the parts with MIM technology, proposed to use a new metal powder mixture (feedstock are presented) with the increased size of the powder to 50 microns. New feedstock are presented recommended for use in the manufacture of parts with a wall thickness of 5 mm. Shows the main physical and technological properties of new metal powder mix (feedstock) 40ХМА of steel intended for the manufacture of parts via MIM technology. Given the results of determination of granulometric composition and particle shape. The obtained values of tensile strength, hardness and roughness. The results of determining the dependence of viscosity on shear rate. For simulation of rheological properties of selected elastic-visco-plastic model of Bingham type with nonlinear dependence of viscosity on shear rate and temperature. The example of the calculation of feedstock fill the cavity of the mold. The analysis of defects in green part, associated with an irregular velocity field in the flow channels feedstock form.
