Accurately determining the temperature during the printing process is crucial for additive manufacturing. Both excessively low and excessively high temperatures affect the quality of the printed product. To ensure product quality, the temperature during the printing process must be higher than the melting temperature of the printing material. This study determines the influence of printing process parameters on the temperature distribution during the printing of Ti6Al4V powder material using the Selective Laser Melting (SLM) method.

The most significant thing for the current team of scientists is not only specific mechanisms or policies, but also the strategic trust of the Party, the State, and the National Assembly.

Self-aligning elastic diaphragms are core components in the hydrostatic load balancing system of thrust bearings in large-capacity hydropower plants. During operation, these parts must withstand extremely high axial loads and hydraulic pressure, requiring their manufacturing materials to possess superior mechanical properties, high fatigue strength, and resistance to corrosion in hydraulic oil environments. The research focuses on analyzing and selecting materials; optimizing sheet metal forming technology using a multi-stage deep drawing process for austenitic stainless steel SUS 304; and simultaneously establishing a rigorous on-site static load testing procedure to validate product performance and reliability. The research results not only solve the problem of localizing a strategic component, reducing dependence on imported equipment, but also open up prospects for applying this technology to other hydropower plants, contributing to energy security and enhancing domestic precision mechanical engineering capabilities.

The paper presents a study on the current status of emissions and technical solutions aimed at upgrading flue gas treatment systems at thermal power plants belonging to Vietnam Electricity (EVN).

In the current period, to meet the country's socio-economic development program, many thermal power plants have been, are being, and will be newly invested and constructed.

In recent years, thanks to the promotion of scientific research, technology application and transfer, and innovation, the National Research Institute of Mechanical Engineering has become a leading scientific research and development organization in Vietnam in the fields of mechanical engineering, automation...
