Sintering: What it is
Sintering is a thermomechanical process in which a porous material with low mechanical properties obtained by powder pressing (commonly called green-part) is subject to a combined temperature and pressure effect so as to obtain a component with density close to the unit and high mechanical features. Sintering is normally carried out in specific furnaces and controlled atmospheres. The use of pressure is widespread though there are sintering treatments carried out at low pressure or in vacuum. The components made by sintering can undergo further mechanical processes or thermochemical treatments.
Sintering Simulation: How it works
The simulation of powder metallurgy consists in developing numerical models to simulate the powder pressing and sintering phase for the production of metal materials.
The powder metallurgy process comes with several benefits, such as low use of energy and raw materials, and it is suitable for the large-scale industrial production of components with complex shape. However in components obtained through powder metallurgy, the mechanical properties reached are inadequate for high load applications. Therefore it is necessary to increase the final density of the sintered product, thus increasing its strength and fatigue properties and radically improving the mechanical properties.
This makes sintered simulation fundamental, paying special attention to simulation of elastic-plastic deformations that occur during densification.
In fact the use of Finite Element Modelling (FEM) allows you to assess the elastic-plastic behaviour of the material during rolling.
Thanks to DEFORM simulation software, sintering simulation allows you to functionally verify the workpiece, to assess elastic-plastic behaviour predicting any distortions, optimise process parameters and assesse density distribution.
What customers say about DEFORM:
- EXCELLENT AGREEMENT OF “SOFTWARE RESULTS” WITH “REALITY” DEFORM is the most widely used cold forming simulation software in the world
- SAMPLING IMMEDIATELY POSITIVE The simulation makes it possible to identify defects obtained during forming, to understand their causes and therefore to undertake the right corrective actions
