This article aims to observe the microstructure, mechanical properties, and interface bonding of a 0.35Cr-1.9Ni-0.55Mo alloy deposited on 20Cr steel by wire and arc-based directed energy deposition (WA-DED). For this purpose, different characterization te... see more

This paper aims to investigate the fabrication of high strength low alloy (HSLA) steels by wire and arc-based directed energy deposition (WADED). Firstly, the relationship between the process variables (including the travel speed-V, the current-C, and the... see more

It is well-known that II-VI compounds occupy a very relevant place in the whole context of semiconductors. In particular, II-VI semiconductor and isolating or quasi-isolating oxides play an important role. Among these materials, we can mention zinc oxide ... see more

A series of pure and copper-doped cobalt oxide films was prepared by plasma-enhanced metalorganic chemical vapor deposition (PEMOCVD). The effect of Cu-doping on the chemical structure and morphology of the deposited films was investigated. Raman and FTIR... see more

This research aims to perform the geochronology of surface coverings in low Holocene marine, fluvial-marine, and fluvial terraces, associating the genesis of paleo-forms with the occurrence of Holocene climatic pulsations, the consequential switches betwe... see more

The problem of supersonic streamlining of an aerodynamic (AD) body, “a plate blunted by a cylinder”, by a flow with the freestream Mach number M = 4 containing an external energy source has been studied, taking into account physicochemical transformations... see more

3D Printing Machine is a machine that works with the basic principle of CNC, namely the movement of the machine in making the workpiece which is regulated by the G code in 3 coordinate axes x, y, and z. Based on how it works, 3d printing machines are clas... see more

In this review, scaling issues in additive manufacturing (AM) processes are discussed based on multiple factors. Scaling issues arise mainly due to design and control of the AM system and also while attempting to achieve desired accuracy. Based on current... see more

O objetivo desse estudo foi identificar os depósitos de leques aluviais colmatados ao longo da base das escarpas do Quadrilátero Ferrífero.  A referida identificação ocorreu primeiramente em gabinete, onde foram realizadas leituras de trabalhos relac... see more
