High temperature mechanical properties of Ni3Al a Ni3Al-Mo alloys in compression
Original language description
High-temperature tests of the alloys Ni3Al and Ni3Al-Mo were performed under compression. The alloys were tested in as-cast and directionally solidified state at the temperatures of 800 and 1 000 °C. As-cast samples were prepared by method of vacuum induction melting. Solidified samples were prepared from castings by Bridgman’s method. The samples were subjected to compression tests under elevated temperatures. The tests were performed on the equipment Gleeble 3800. Obtained values of selected mechanical characteristics of unalloyed and Mo alloyed alloys and also alloys in as-cast and directed state were compared. Alloyed alloys in as-cast state show higher values of yield strength and maximal achieved stress. The alloys in directed state have better values of ductility corresponding to the achieved maximal stress during compression tests. Evolution of stress-strain curves under compression in as-cast samples has very similar character, when a significant decrease of tension occurs at the achieved deformation of 0.15. In the case of directionally solidified samples this evolution depends on created structure and temperature of testing.
