“…The findings indicated that tempering at T6 and T7 temperatures for 250 minutes produced the highest resistant to stress corrosion cracking (SCC). However, samples that had been annealed for 8 minutes at 200°C showed decreased resistance to stress corrosion cracking [7]. The results of the electrochemical tests showed the fact that the PEO covering increased corrosion resistance, but that it had no effect on SCC protection within the ASTM D1384 solution used for the sample.…”

Tensile stress combined with exposure to a corrosive environment result in a cracking process known as stress corrosion cracking (SCC). It falls in the threshold of the material's fatigue limit and dry cracking. Tensile stress can be applied directly or exist as residual stress within the material. SCC results from specific combinations of composition, environment, and stress. Processes like cold forming, welding, heat treating, machining, and grinding introduce residual stresses. Stress erosion cracking (SCC) occurs when cracks form under static tensile stress and the environment around us . It develops by the result of the interaction between mechanical stress and corrosion/oxidation reactions. The occurrence and progression of SCC depend on the materials, applied loads, and environmental conditions. Some Contributing Factors to SCC In summary, two main features of SCC are emphasized: localization and acceleration of oxidative reactions.

Solar photovoltaic technologies direct absorption of sunlight particles solar energy is useful energy solar photovoltaic technologies like photovoltaics are light photons as electricity as voltage b.v. From the conversion process. As named. This is the photoelectric effect is called this event was first used in 1954. Scientists at bell lab currently when exposed to light work from forming silicon have developed a solar cell that works cost competitiveness in multiple regions and photovoltaic systems for electricity are used extensively to aid in performance. Pv-related goods and equipment generate electricity from the sunshine. Ministry of energy PV photovoltaic technology what it means and how it works PV products and solar devices convert light energy into electrical energy. Single a cell is a photovoltaic device. Various semiconductor materials in PV cells are used. In semiconductor light when exposed, it absorbs light energy in matter called electrons and converts to negatively charged particles. This extra energy turns the electrons into electricity and allows the material to flow through. A variety of PV cells and semiconductor materials are used. Semiconductors when exposed to light, it is of light electrons absorb energy negatively in the sense of called converts to charged particles. Among the several renewable energy technologies, solar photovoltaic (PV) technology is one of the most developed and field-tested. This chapter is designed to provide a thorough introduction to PV technology and to provide the technical information required to comprehend this technology. These extra energy electrons allow current to flow through the material.

Choosing the most suitable alternatives can be challenging in process engineering. Typically, there is a need to evaluate and rank alternatives using various criteria, such as environmental impact, when making decisions. This paper employs a novel integration of Life Cycle Assessment (LCA) and Multi-Criteria Decision-Making (MCDM) methods to evaluate the sustainability of different cement alternatives in South Africa. The LCA assesses the environmental impact, considering 18 midpoint categories, while Complex Proportional Assessment (COPRAS) and Additive Ratio Assessment (ARAS) methods were used as MCDA methods to rank and select the best alternatives. Across 18 impact categories, including global warming, ozone depletion, ecotoxicity, and resource scarcity, CEM I cement exhibited notable global warming emissions, ranking fourth. COPRAS and ARAS methods systematically ranked alternatives based on impact categories, consistently identifying CEM II/B-V cement as the most preferred alternative. This top ranking was attributed to its low environmental impact and high utility score. Notably, CEM III/A cement, despite low global warming emissions, ranked least preferred due to concerns about raw material-related environmental impacts. The paper highlights environmental hotspots for each cement type and underscores the importance of sustainable fuel and raw material selection in production. The results emphasize the necessity of reducing clinker content, exploring alternative fuels and raw materials, and adopting interventions like carbon capture and storage to enhance sustainability in cement production. The paper concludes that the integrated LCA and MCDM approach provides valuable insights for decision-makers in the cement industry, aiding the pursuit of more sustainable practices and calling for further research on the environmental impact of specific raw materials and fuels.
