14. Correlação entre transformações de fases e comportamento mecanico de ligas Ti-Nb-Sn e sua aplicação na concepção de implantes ortopedicos com propriedades otimizadas / Correlation between phase transformations and mechanical behavior of Ti-Nb-Sn alloys and its applications in the design of orthopedic implants with optimized characteristics
β type Ti alloys exhibit versatility in terms of mechanical properties, which can be tailored by using specific heat treatment conditions. In this work, Ti-Nb-Sn alloy samples were prepared, processed and characterized, aiming to produce femoral stems of total hip prostheses. The research included evaluations of phase transformations during heat treatme

16. MONOENERGETIC AND POLYENERGETIC GAMMA RAY COMPUTER TOMOGRAPHY FOR MULTIPHASE SYSTEMS ANALYSIS / Análise de sistemas multifásicos utilizando tomografia computadorizada Gama monoenergética e polienergética
It is important to recognize that at the heart of chemical transformations in all process and energy industries is multiphase reator technology, as over 99% of reator systems require the presence of more than one phase for proper operation. Tomography is a powerful technique capable of determining the effect of operating and design parameters on the phase ho
