Construction of a True Compaction Curve: critical review of the closed die compaction test for powdered materials
Barrera, Helver Mauricio (Programa Editorial Universidad Autónoma de OccidenteCali, 2017)Powder compaction keeps as a main process within the realm of powder metallurgy and the investigation towards even more accurate powder compaction engineering has achieved many goals, whilst at the same time faces ... -
Shear-wave corner retroreflector device for ultrasonic measurement of viscosity
Barrera, Helver Mauricio; Formigoni, Paulo O.; Buiochi, Flávio; Franco Guzmán, Ediguer Enrique (Revista Ultrasonics, 2021)This work shows a novel ultrasonic viscosity measurement device with increased sensitivity. The measuring principle is based on the determination of the complex reflection coefficient of shear-waves at the solid–liquid ...
