Influence of hydrogen on the microstructure and fracture toughness of friction stir welded plates of API 5L X80 pipeline steel
(2019-08-30)
In this work, the influence of hydrogen on the microstructure and fracture toughness of API 5L X80 high strength pipeline steel welded by friction stir welding was assessed. Samples were hydrogenated at room temperature ...
The effect of simvastatin treatment on bone repair of femoral fracture in animal model
(Informa Healthcare, 2015-04-01)
The aim of this research was to evaluate the fracture healing area in osteoporotic femur of female rats restrained by stainless steel wire by statin administration in two different doses (5 mg and 20 mg). Ninety female ...

Estudo da influência da fase sigma nas propriedades mecânicas de dureza e resistência ao impacto de um aço inoxidável superduplex
(Universidade Tecnológica Federal do ParanáLondrinaBrasilEngenharia de MateriaisUTFPR, 2019-11-28)
Superduplex stainless steels have excellent combinations of mechanical properties and high corrosion resistance, for these reasons they are applied in the oil and gas industries, offshore platforms and other extremely ...
Influence of phase composition on the sliding wear of composites in the system CaZrO3–MgO–ZrO2 against ZrO2 and steel
(Elsevier Science, 2016-10)
An attractive way to obtain low cost calcium zirconate (CaZrO3) composites is mixing natural limestone or dolomite with zirconia. These CaZrO3 based ceramic composites were often investigated as a promising high refractory ...
Microstructural characterization of joints of maraging 300 steel welded by laser and subjected to plasma nitriding treatment
(2016-01-01)
Amongst the ultra high strength steels, the maraging steels have been noticed because they maintain the fracture toughness superior to other steels of their class. The main difference is the way they acquire resistance. ...
Influence of phosphorus content and quenching/tempering temperatures on fracture toughness and fatigue life of SAE 5160 steel
(ABM, ABC, ABPol, 2010)
This study investigates the influence of quenching/tempering temperatures on the fracture toughness and fatigue life of SAE 5160 steel, considering different phosphorus contents. Quenching and tempering treatments were ...
Effect of alpha prime due to 475 degrees C aging on fracture behavior and corrosion resistance of DIN 1.4575 and MA 956 high performance ferritic stainless steels
(SPRINGER, 2008)
The 475 degrees C embrittlement in stainless steels is a well-known phenomenon associated to alpha prime (alpha`) formed by precipitation or spinodal decomposition. Many doubts still remain on the mechanism of alpha` ...
Failure analysis of a martensitic stainless steel (CA-15M) roll manufactured by centrifugal casting. Part II: Thermal stress analysis by FEA
(Oxford, 2014-02)
A martensitic stainless steel (CA-15M) roll manufactured by centrifugal casting and used as a glass roller failed prematurely after six rolling campaigns. A previous fractographic investigation showed that the failure of ...
