Oxidation behaviors and microstructural alterations of a Mo(Si,Al)(2)-based composite after heating at 1580 degrees C either in a furnace (ex-situ) or via alternating current (in-situ)

摘要

The commercial heating element Kanthal Super ER (Mo(Si,Al)(2)-based composite) was oxidized at 1580 degrees C for 24 h up to 1 year using two methods: (1) a furnace set at the desired temperature, (2) passing an alternating current (AC) through the material.
