Mg-Cu-Ho alloy；Using the grain size and pattern of alloy lower after metallography microscope sem observation as cast condition and solution treatment, use
Model Phenom ProX scanning electron microscopic observation tissue and fracture surface of sample pattern, using Instron8801 universal material testing
The tensile strength of machine measurement alloy.
As shown in Figure 1, the Al-Zn-Mg-Cu alloy tissue crystal grain for not adding rare earth Ho and Zr is largely column crystal
Grain, and it is coarseer to be present in the cocrystalization compound between crystal grain and crystal boundary.And after being added to 0.5% rare earth Ho,
Crystal grain in Al-Zn-Mg-Cu-Ho alloy has obtained certain refinement, and the cocrystalization compound being present between crystal boundary and crystal grain is thin
Change particularly evident, crystal boundary is completely clear；On the basis of 0.5% rare earth Ho is added, it is added to the Al-Zn-Mg- of 0.2%Zr element
Cu-Ho-Zr alloy (embodiment 2) tissue crystal grain more refines, and the pattern of crystal grain more levels off to spherical shape.
As shown in Fig. 2, a part of Solid Solution of Second Phase Particles is in matrix, and another part is due to adding after solution treatment
The Microalloying Effect for having entered rare earth Ho and Zr combines with Al, Cu, Zn etc. around crystal boundary and forms the phase that can be dissolved in matrix,
So that the second phase oversize grain that part concentrates on crystal boundary has dissolved in matrix again, reduce the crystalline substance of Al-Zn-Mg-Cu alloy
Boundary's segregation, improves tissue, optimizes performance.
As shown in figure 3, the tensile strength of alloy obtains after addition rare earth Ho for as cast condition Al-Zn-Mg-Cu alloy
It is promoted.Meanwhile in the case where rare earth Ho content is constant, with the increase of Zr content, curve is in downward trend after first rising,
When content is 0.2%Zr, tensile strength reaches maximum value (328MPa).This illustrates that Al-Zn-Mg-Cu alloy is moved back by homogenization
After fire processing and solution treatment, the solute element in alloy has dissolved in matrix, meanwhile, the second phase particles of part segregation also incorporate
Matrix makes matrix generate distortion of lattice, hinders dislocation motion, thus improve the intensity of alloy, and the addition of Ho and Zr
The non-spontaneous nucleation of formation plays the role of refining crystal grain.When Ho content is constant, with the increase of Zr content, refinement is brilliant
The effect of grain and solution strengthening is improved, so that the tensile strength of Al-Zn-Mg-Cu alloy be made more to be significantly improved.
