Molybdenum powder, chromium powder, vanadium powder being used cooperatively under, collaboration improve high-performance aluminium alloy die casting tensile strength and elongation percentage.
In addition, 5 valence electrons of d sub-layer are in semisteady-state since the outer-shell electron of molybdenum element is 4d55s1, easily draw
Electron transfer is played, so molybdenum is preferentially dissolved in solid solution, the interparticle bond energy increasing of alloy interior metal is promoted (covalent bond can be formed
And metallic bond)；Its atomic radius differs each other, when equilibrium is reached, necessarily leads to the distortion of lattice and the reduction of free energy, this
Sample has been considerably improved tensile strength and elongation percentage.
After material longtime running at high temperature, a part of molybdenum can be precipitated out of solid solution, be transferred in carbide, cause solid
Poor molybdenum in solution, to reduce the croop property of material.To overcome this disadvantage, in high-performance aluminium alloy die casting material simultaneously
It joined a small amount of metallic element vanadium.The outer-shell electron of vanadium is 3d34S2, and d sub-layer electronics is extremely unstable, with the affinity of carbon compared with
Greatly, VC and V4C3 can be generated with carbon, they form tiny, uniform, highly dispersed distribution in high-performance aluminium alloy die casting
Particle, for these Particle Distributions on transgranular and crystal boundary, effect is to reduce the speed of atom diffusion, hinders the aggregation of carbide long
Greatly, to improve tensile strength and elongation percentage.Further, since the affinity of vanadium and carbon is greater than the affinity of molybdenum and chromium and carbon,
The transfer of molybdenum and chromium from solid solution into carbide can be hindered, the dilution of molybdenum and chromium in solid solution is avoided, has reached stable base
Body tissue, the purpose for improving strengthening effect, to improve tensile strength and elongation percentage.
The above content is it cannot be assumed that present invention specific implementation is only limited to these instructions, for the technical field of the invention
Those of ordinary skill for, under the premise of not departing from present inventive concept, a number of simple deductions or replacements can also be made, all answers
