实验和有限元模拟已进行表征的试样/模具/冲头设置和其演变过程中的场激活烧结的温度分布。在径向和轴向方向上的试样中发现了显着的温度梯度。冲头经历最高温度，而最低温度在模具外表面上，这是为了控制目的而监测温度的地方。试样与模具表面的温差随温度的升高而增大。为了知道真实的样品温度，相对于通常使用的表面温度的基于校准的校正是必要的。
Experiments and finite element simulations have been conducted to characterize the temperature distribution in the specimen/die/punch setup and its evolution during field activated sintering. Significant temperature gradients were found in specimen in both radial and axial directions. The punches experience the highest temperatures, while the minimum is on the outer die surface, which is where the temperature is monitored for control purposes. The temperature difference between the specimen and die surface increases with temperature. In order to know the true specimen temperature, a calibration-based correction with respect to the typically used surface temperature is necessary.
