3.1 Dimensional Precision
3.2 Geometrical Precision
4 Conclusions
-
Dimensional change of diameters increases on increasing sintering temperature, irrespective on size, while dimensional change of height increases on increasing sintering temperature and size, and the effect is more evident for small sizes. As by the design procedure previously developed, this result does not represent an obstacle to sintering at high and very high temperature.
-
The influence of high sintering temperature on geometrical characteristics is surprisingly low. The worsening, if any, never determines tolerance exceeding.
-
High sintering temperature, determining noticeable improvement in the mechanical properties of sintered parts, can be used without significant detriment of dimensional and geometrical precision.
