耐高温金属用作热电偶,主要是因为它们的熔点高。耐高温金属以及一些可以作合金元素的其他高温金属的物理性质示于表1。用于高温的金属中,主要的有钨(W)、
Thermostable metals are used as thermocouples mainly because of their high melting point. The physical properties of refractory metals and some other high temperature metals that can be used as alloying elements are shown in Table 1. For high temperature metal, the main tungsten (W),
