| Abstract: | This paper presents a study of the microstructure of a TiNiAl alloy. Metalloscope and scanning electron microscope are used to observe the surface microstructure of as-cast and as-anneal alloy. Grain refinement turn out in the alloy and a few minor precipitates also appear after annealing. The inner microstructure of as-forge alloy is studied with transmission electron microscope. Some typical martensite plates are found in it. The precipitate appears to he a long-elliptical-bar. A crystal boundary plane is also found in the test. |
