摘要：

Based on the concept of melt residual bonds, a calculating model quantitatively describing the evolution of the residual bond structure of titanium melt at the melting point or in a certain range above the melting point was established; i.e., both the size dS and the bond number n of the residual bond structure decrease monotonously with the increase of temperature. By mathematical deduction, a linear relationship between the residual bond structure size dS and the dynamic viscosity of Titanium melt was revealed, i.e., = 0.876 + 0.471·dS, which is of great significance to the investigation of the relationship between the melt microstructure and the macroscopic properties of metals with high melting temperature.
