【Abstract】 The plasticity-induced heating in metallic materials is crucial for understanding their mechanical and thermodynamic behaviors. The Taylor-Quinney Coefficient(TQC) serves as a key parameter for quantifying the conversion of plastic work to heat during deformation. This review systematically examines the recent advances in TQC, focusing on its fundamental principles, experimental investigations, theoretical models, and computational simulations. First, the definition and thermodynamic background of TQC are outlined, along with its role in the distribution between heat and stored energy of cold work(SECW). Experimental studies on TQC, including the effects of high strain rates and temperature on heat conversion,are then summarized. Next,theoretical models of TQC are discussed, emphasizing the contributions of dislocation mechanics and internal state variable models in describing TQC under various loading conditions. Finally,computational approaches,such as finite element analysis and molecular dynamics simulations,are highlighted for their role in investigating the influence of microstructure on TQC. Future research will focus on TQC under multi-scale simulations,extreme conditions,and the micro-structural control of energy conversion,aiming to enhance the development of new materials and optimize high-performance material designs.更多还原
