The tracer element molten (TEM) method has been developed for flow visualization of molten Titanium in dental precision casting. The principle of this technique is as follows. When Titanium is cast, the tracer element wire inserted previously into the selective point of the sprue is molten little by little and distributed according to the molten Titanium flow in the mold cavity. After solidification, to observe the flow pattern, the tracer element needs to be analyzed on a section of the casting by EPMA equipped with the stage scan mapping system. This technique using Ag, Au, Pd or Pt as a tracer has been applied to some simple castings in shape and has been confirmed to be a very powerful technique for Titanium flow visualization in dental castings.
示踪元素熔融（TEM）法已被开发用于牙科精密铸造中熔融钛的流动可视化。该技术的原理如下。当铸造钛时，预先插入浇道选定点的示踪元素丝会逐渐熔化，并根据模腔内熔融钛的流动进行分布。凝固后，为了观察流动模式，需要在配备了台面扫描映射系统的电子探针微分析仪（EPMA）上对铸件的一个截面进行示踪元素分析。这种使用银、金、钯或铂作为示踪剂的技术已应用于一些形状简单的铸件，并已被证实是一种用于牙科铸件中钛流动可视化的非常强大的技术。
