Effect of Copper Additions on Secondary Carbide Precipitation in High Chromium with Cast Iron0.5 and 2 wt%. The destabilization heat treatments were undertaken at temperatures of 850, 950, and 1050 .C between 5 and 480 min. Characterization was carried out by X-ray diffraction (XRD), optical and electron microscopy, image analysis, and energy-dispersive spectroscopy (EDS) microanalysis; the

Thermal Behavior of an HSLA Steel and the Impact in Phase Transformation: Submerged Arc Welding (SAWctures, generally associated with the heat-affected zone (HAZ). For this reason, it is very important to know the behavior of this area before welding. This paper presents a study of the thermal behavior and its effect on phase transformations in the HAZ, depending on cooling rates (0.1–200 .C/s) to

Effect of Hydrogen on a Microalloyed Steel Permeatendergo heat treatment at a temperature of 1000 .C for 30 min. The formation of microstructures are obtained at temperatures of 204, 315, 426, 538, and 650 .C for 30 min and cooled in water. The permeation tests were carried out according to the modified Devanathan-Starchurski setup. Microstructural

Metallurgical Study of Mechanical Milling Mechanism in Eutectic Nanopowders: The Role of Heterogeneirried out using chemical arguments, as well as X-ray powder diffraction and microscopy techniques. In addition to a change of energy source input, growth of eutectic alloys with the addition of Pb–Sn nano-heterogeneities promotes a more refined microstructure. The conventional melting/solidification

Biosynthesis of Silver Nanoparticles Using Extracts of Mexican Medicinal Plantsried to evaluate their influence on the nanoparticles characteristics such as size and shape. Several characterization techniques were employed. UV-Vis spectroscopy revealed the surface plasmon resonance in the range of 400–500 nm. The X-Ray diffraction results showed that the nanoparticles have a f
