Journal ArticleDOI
The "quenching and partitioning" process: background and recent progress
TL;DR: A new process concept, "quenching and partitioning" (Q&P) has been proposed recently for creating steel microstructures with retained austenite as discussed by the authors.
Journal ArticleDOI
A comparison between the Warren-Averbach method and alternate methods for X-ray diffraction microstructure analysis of polycrystalline specimens
TL;DR: In this paper, the authors compared the performance of the Balzar and Enzo methods and the Warren-Averbach method for the analysis of X-ray diffraction profile.
Journal ArticleDOI
Thermodynamic Evaluation of Carbide Precipitates in 2.25Cr ¾ 1.0Mo Steel for Determination of Service Degradation
Bojan A. Marinkovic,Roberto R. de Avillez,Simone Kessler Barros,Fernando Cosme Rizzo Assunção +3 more
TL;DR: In this paper, a software for thermodynamic calculations was used to evaluate the thermodynamically stable carbides over the temperature range of interest (700-1040 K) and the theoretical carbide nucleation sequence was also established.
Journal ArticleDOI
Processing of bulk Bi-2223 high-temperature superconductor
A. Polasek,Luiz Antonio Saléh,H.A. Borges,Eduardo Novaes Hering,Bojan A. Marinkovic,Fernando Cosme Rizzo Assunção,E.T. Serra,Glória Suzana Gomes de Oliveira +7 more
TL;DR: In this article, a process for improving the microstructure of Bi-2223 bulk samples is investigated, in which the precursor blocks are processed by sintering with a further partial melting step, in order to enhance the Bi-2Sr2Ca2Cu3 O10+x grain texture and to healing cracks induced by pressing.
Journal ArticleDOI
Development of Bulk Bi2+xSr3-yCa yCu 2O8+delta Superconductors by Partial-Melting Route for Fault Current Limiters Application
Bojan A. Marinkovic,Sike Xia,Luiz Antonio Saléh,Marcio Antonio Sens,E.T. Serra,Roberto R. de Avillez,Fernando Cosme Rizzo Assunção +6 more
TL;DR: In this article, the production of bulk Bi2+xSr3-yCayCu 2O8+D (Bi-2212) superconductors for fault current limiter application was developed via a partial-melting route.
