direct alloying is difficult to be realized in an immiscible Mo-Ag system with a positive formation heat due to the absence of thermodynamic driving force at *** this work,a direct alloying method is developed to realize the direct alloying between Mo and Ag and construct Mo-Ag *** direct alloying method was mainly carried out through a direct diffusion bonding for Mo and Ag rods at a temperature close to the melting point of Ag(Tm Ag).Then the microstructure and phase constitution of the as-constructed Mo-Ag interface are *** results show that Mo-Ag metallurgical bonding interface has been constructed successfully,indicating that a direct alloying in the immiscible Mo-Ag system has been ***,mechanical tests are carried out for the Mo-Ag joints prepared through the direct alloying *** test results show that the average maximum tensile strength of the joints is about 107 *** effect of alloying parameters on the tensile strength is also discussed,which shows that there is an effective temperature range for the direct alloying between Mo and ***,an improved thermodynamic model that considers the formation of Mo-Ag crystalline and amorphous phase is presented to reveal the thermodynamic mechanism of the direct *** the calculation and differential scanning calorimetry(DSC)tests results,the Gibbs energy diagram for the direct alloying is *** is confirmed that the co-release of storage energy and surface energy can serve as the thermodynamic driving force to overcome the effect of positive formation heat and lead to direct alloying for Mo-Ag systems.
