Evaluation of the Abnormal Grain Growth in an ASTM 213 Grade T91 Steel

Autor: C. A. Danon, C. García de Andrés, J.L. Gibson, Catalina Jimenez, M.I. Luppo

Publikováno v: Procedia Materials Science. 8:1118-1126

A study of the austenite grain growth of an ASTM A213 T91 steel held at 1050 °C for increasing times is presented. The prior austenite grain size distribution (PAGSD) at various holding times was determined using scanning electron microscopy. Taking

Evolution of precipitated phases during prolonged tempering in a 9%Cr1%MoVNb ferritic–martensitic steel: Influence on creep performance

Autor: José María Cabrera Marrero, C. A. Danon, M.I. Luppo, H. De Cicco, N. Zavaleta Gutiérrez

Publikováno v: Materials Science and Engineering: A. 528:4019-4029

Ferritic–martensitic steels of the 9%Cr1%Mo type have been extensively used in power plant components, heat exchangers, piping and tubing, etc., due to an excellent combination of properties such as creep resistance, toughness and resistance to oxi

Thermodynamic Modeling in Reduced Activation Steels

Autor: C. A. Danon, C. Servant

Publikováno v: ISIJ International. 45:903-912

Reduced Activation (RA) martensitic steels of the 9/11CrWVTa type are promising candidates for fusion reactor applications as long as they exhibit good mechanical properties—similar to those of commercial martensitic steels of the 9/12CrMo(NbV) typ

A thermodynamic evaluation of the Ta–V system

Autor: C. Servant, C. A. Danon

Publikováno v: Journal of Alloys and Compounds. 366:191-200

We present a thermodynamic study of the Ta–V system based on the Calphad–Thermocalc approach. This work is part of a broader project concerning the thermodynamic description of Ta-containing low activation steels, which were developed in the past
