Journal ArticleDOI
Effect of volume fraction of phases and precipitates on the mechanical behavior of UNS S31803 duplex stainless steel.
TL;DR: In this article, the effect of the microstructure on the mechanical behavior of a grade UNS S31803 duplex stainless steel was studied and the results demonstrate the sensitivity of the steel to the annealing temperature.
Journal ArticleDOI
Fatigue crack growth analysis of pre-strained 7475–T7351 aluminum alloy.
TL;DR: In this paper, the results showed that both fracture toughness and FCG resistance decreased with an increase in the tensile pre-strain level, and the modified Forman model provided the best fit to the FCG rate data as compared with the other two models.
Journal ArticleDOI
Microstructure and mechanical properties of a flash butt welded pearlitic rail
Rodrigo Rangel Porcaro,Geraldo Lúcio de Faria,Leonardo Barbosa Godefroid,Gabriela Ribeiro Apolonio,Luiz Cláudio Cândido,Elisângela Silva Pinto +5 more
TL;DR: In this article, the microstructural evolution of the heat affected zone is clarified with the aid of dilatometry, and a dilatometric based methodology is proposed to define a process window and control the post-weld cooling rate at the rail head in order to improve the weld performance due to a better hardness profile, without increasing costs or welding time.
Journal ArticleDOI
Effect of chemical composition and microstructure on the fatigue crack growth resistance of pearlitic steels for railroad application.
Leonardo Barbosa Godefroid,Luciano Pessanha Moreira,T.C.G. Vilela,Geraldo Lúcio de Faria,L.C. Candido,Elisângela Silva Pinto +5 more
TL;DR: In this paper, the microstructure and mechanical behavior of two pearlitic steels used in Brazilian railroads, a C-Mn-Si steel and a V-microalloyed steel, were characterized by light optical, scanning electron and atomic force microscopy.
Journal ArticleDOI
Statistical modeling of fatigue crack growth rate in Inconel alloy 600
TL;DR: In this paper, Collipriest and Priddle FCGR models were proposed to model the data and these models were modified to obtain a better fit to the data, especially in the near-threshold region.
