Effect of Annealing Conditions on the Dissolution Process of Complex Carbonitrides in a V-Nb-Ti Microalloyed Steel

Autor: Ervis Díaz, Gloria Basanta, Carlos Parra, A.L. Rivas

Publikováno v: Materials Science Forum. 941:21-26

The present work has been undertaken to assess the evolution of dissolution process of large dendritic precipitates in a V-Nb-Ti microalloyed steel. The study was performed by reheating the samples at 1250°C, simulating the industrial reheating prac

Study of austempering kinetics of high silicon bainitic cast steels

Autor: Roberto Enrique Boeri, Juan Miguel Massone, Alejandro Daniel Basso, A.L. Rivas, Nicolás Emanuel Tenaglia

This study investigates the effect of chemical composition and microsegregation on the bainitic transformation of high Si cast steels at two different austempering temperatures. The advance of the bainite precipitation as a function of time and tempe

Phase Transformation of Amorphous Rice Husk Silica

Autor: A.L. Rivas, Mauricio Cornejo, Guillermo Solórzano, Andrés Rigail, Grace Vera, Víctor Palacios

Publikováno v: Frontiers in Materials Processing, Applications, Research and Technology ISBN: 9789811048180

This work aims at assessing the crystallization process of amorphous silica from rice husk (RH) by in situ X-ray diffraction, upon heating up to 1450 °C in a high-temperature chamber. The study includes microstructural characterization by transmissi

Characterization of Rice Husk and the Crystallization Process of Amorphous Silica from Rice Husk Ash

Autor: Grace Vera, A.L. Rivas, Andrés Rigail, Víctor Palacios, Mauricio H. Cornejo Martínez

Publikováno v: Proceedings of the 14th LACCEI International Multi-Conference for Engineering, Education, and Technology: “Engineering Innovations for Global Sustainability”.

Rice husk (RH) is a rich silica by-product of rice production with great potential for industrial applications. After combustion, a rice husk ash rich in silica is obtained, with some amount of other inorganic components constituted mainly of alkalin
