As a kind of high performance engineering material, building forgings have been widely used in the construction industry. The thermodynamic behavior of forging process has an important influence on material properties and product quality. Therefore, this paper will discuss the theory and application of finite time thermodynamics of building forgings.
Fundamental principles of finite time thermodynamics
Finite-time thermodynamics is a branch of thermodynamics that studies how thermodynamic systems change in finite time. It is based on the first and second laws of thermodynamics, combined with the principle of conservation of energy and other basic principles to analyze and optimize the energy efficiency of the system.
Thermodynamic characteristics of building forgings
Building forgings have unique thermodynamic characteristics in material selection, design and manufacture. First of all, materials are usually selected with high strength, corrosion resistance and good thermal stability, such as alloy steel and aluminum alloy. Secondly, the design should fully consider the processing and mechanical properties of the material to ensure that the forgings have good manufacturing processability while meeting the requirements of use. In addition, the process parameters such as heating, insulation, deformation and cooling need to be strictly controlled during the manufacturing process to achieve the optimization of the internal organization of the material and the stability of product quality.
Application of finite time thermodynamics to building forgings
Material selection design: Through finite time thermodynamic simulation, the properties of different materials can be compared, which provides a theoretical basis for the material selection of building forgings. At the same time, combining with the thermodynamic characteristics of the material, the design scheme of the forging can be optimized, and its bearing capacity and service life can be improved.
Manufacturing process: Finite time thermodynamics can simulate the process of heating, insulation, deformation and cooling of materials in the forging process, helping engineers understand and master the influence of process parameters on material properties, so as to optimize the manufacturing process and improve production efficiency and quality.
Quality inspection: The use of finite time thermodynamic method can detect whether there is residual stress, micro-cracks and other defects inside the forging. By simulating the behavior of the material such as thermal expansion and cold contraction, the stability and reliability of the forging can be evaluated in different environments, which provides strong support for the quality inspection of the product.

This paper discusses the theory and application of finite time thermodynamics of building forgings. Through the finite time thermodynamics principle, we can deeply understand the thermodynamic characteristics of building forgings in material selection, design, manufacturing and other aspects, and effectively apply to material selection design, manufacturing process and quality inspection. With the continuous development of computer technology and numerical simulation methods, the application of finite time thermodynamics in the research of building forgings will be more extensive and in-depth, and provide strong support for the sustainable development of the building industry.
Looking forward to the future development trend and application prospects, finite time thermodynamics will play a greater role in the research and development of building forgings, energy saving and emission reduction, quality improvement and so on. For example, by simulating the change of material properties in different environments, more targeted and high-performance building forging materials can be developed; Combined with green manufacturing technology, optimize the energy consumption and waste emission of forging process to achieve energy saving and emission reduction; Based on the finite time thermodynamic principle, a more accurate quality prediction model is established to improve the reliability and stability of forging products.
In short, finite time thermodynamics has a wide application prospect in the field of building forgings, which will provide an important theoretical basis and technical support for the progress and development of the construction industry.
