In this paper, a computational method to predict the corrosion resistance of some sintered iron alloys subjected to a thermochemical treatment is analyzed. The proposed materials are obtained by powder metallurgy (P/M) route. The raw materials are prepared from atomized pre-alloyed iron base powders. The compacted samples were obtained by cold pressing using conventional route. The powders were compacted at a pressures of 400 and 600 MPa. After pressing, the green compacts were sintered in a laboratory furnace. Th...

Application of image processing recognition in the agricultural field is a difficult and intensive task. Recent years developments of technologies such as GPUs (Graphics Processing Units) and the fast development of artificial intelligence algorithms allows the reliability of using computer vision technology to be used for recognition of plants, including weeds, ensuring the efficiency of intelligent agricultural systems. Computer vision technology uses a camera and a computer to identify and measure objects in th...

Due to the increased consumption of S420NL thick steel plates, the world steel price is expected to decrease. The main purpose of this investigation is to find an optimal solution both from a technical and commercial point of view to produce heavy plate 40 mm thick microalloyed S420NL hypoeutectoid steel. The imposed resistance class for this alloy is 420MPa with proven tenacity properties at temperatures up to-50 В°C. The experiment encompasses the necessity of defining a metallurgical route including chemical co...
