In order to improve the mechanical properties of an intermetal1ic compound TiAl, a composite material of TiAl involving a second phase Ti2AIN was prepared by a new combustion reaction method. It is found that Ti2AIN (hexagonal structure) is a rod shape as shown in Fig.1 and its side surface is almost parallel to the basal plane, and this composite material has distinguished strength at elevated temperature and considerable toughness at room temperature comparing with TiAl single phase material. Since the property of the interface of composite materials has strong influences to their mechanical properties, the structure of the interface of intermetallic compound and nitride on the areas corresponding to 2, 3 and 4 as shown in Fig.1 was investigated using high resolution electron microscopy and image processing.

Abrasion mechanism of thermocouple cannula is studied in this article. For different working position and condition, different material should be selected to ensure the working characteristics of thermocouple cannula. Several protection methods were introduced to prolong the sevice life of thermocouple cannula. 1. M-Al series intermetallic compound coating protection method. 2. Metal/ceramic compound coating protection method. 3. Development of new abrasion-resisting material for high temperature according to some special work conditions of thermocouple cannula. With the adoption of those new technologies, thermocouple cannula’s service life can be prolonged to 3~5 times of that untreated.
