Caracterização Térmica e Estrutural de Ligas Ni50Ti50-XHfX.at%

The book "Thermal and Structural Characterization of Ni50Ti50-XHfX.at% Alloys" offers a comprehensive analysis of the thermal and structural properties of Ni-Ti-Hf alloys. It describes the production of these alloys through three different methods: Plasma Arc Casting, Melt-Spinning, and Arc Melting. The author, Roniere Leite Soares, along with Walman B. de Castro, discusses the results of the thermal characterization, including transformation and heat flow temperatures as well as thermal hysteresis. The qualitative and quantitative phase analysis was conducted using X-ray diffraction (XRD), with the Rietveld method employed for structure refinement and to determine variables such as specific density and degree of crystallinity. Furthermore, the microstructural properties of the samples are examined through various microscopy techniques to capture surface features and textures. The results show significant differences in the properties of the alloys, attributed to the specific processing methods used.
