Description

A kind of high-damping Mg-Sn-Ce-Ti alloy
Technical field
The invention discloses a kind of high-damping Mg-Sn-Ce-Ti alloy, belong to complex magnesium alloy application and preparation field.
Background technology
Magnesium and alloy thereof, as one of best structural metallic materials of current damping capacity, also have that density is little, specific strength , heat conduction high with specific stiffness and conduct electricity very well, anti-dynamic impact loads ability is strong, ELECTROMAGNETIC RADIATION SHIELDING ability is excellent, aboundresources Etc. series of advantages, more and more paid close attention to by people, and obtain in fields such as Aero-Space, track traffic, 3C Products Arrive a certain degree of application.And along with the fast development of modern society, instrument and equipment precise treatment day by day, complicate and work The variation of environment, proposes the most urgent requirement to reducing energy consumption and vibration and noise reducing etc..Currently, the alloy unit of low solid solubility Element is effective addition element that magnesium alloy takes into account damping and mechanical property, is favored by Chinese scholars.Ce element is in magnesium Solid solubility be only 0.74wt%, and its content often increases 1wt% alloy yield strength and can increase 148MPa, and has good moulding Property and machinability, get more and more people's extensive concerning all the time.But, the research of existing Mg-Ce alloy damping characteristic is but The most limited.
Additionally, alloying element existing certain research of the impact of damping capacity in magnesium that people are on low solid solubility, and high The elements such as Sn, Y of solid solubility are effective solution strengthening element of magnesium, and numerous scholars think and are unfavorable for damping capacity. CN101440438B discloses " method adding Ce thinning CaMgSn phase in Mg-Sn-Ca magnesium alloy ", mainly have studied tension And creep-resistant property, and do not have in terms of the influence research to damping capacity, and between them, there is no necessary connection.And, Sn element is dissolved in magnesium matrix can increase distortion of lattice, and stacking fault energy (the pure magnesio surface layer of Mg matrix can be greatly reduced simultaneously Mistake can be the basal plane stacking fault energy of 45mJ/m2, Mg-Sn solid solution be 4mJ/m2), this is advantageously possible for the damping capacity of alloy.Cause This, add the Mg-Sn-Ce ternary alloy three-partalloy that a certain amount of Sn element formed in Mg-Ce alloy and study its damping capacity and have very much Necessity, has broad application prospects in actual industrial production.
A kind of alloying element that can improve containing high solid solubility of current needs strengthens the method for designing of magnesium alloy damping performance, And effectively control alloy the second phase microstructure morphology prepares high-damping magnesium alloy to meet defence and military and civilian industry etc. An urgent demand to vibration and noise reducing.
Chinese invention patent CN201511015387.9 discloses a kind of high-damping Mg-Sn-Ce alloy containing trace rare-earth And preparation technology, this magnesium alloy is mainly elementary composition by Mg, Sn, Ce tri-kinds, including the following alloying being distributed in alloy Elemental composition and weight percent content value thereof: Sn=0.5%-3.5%, Ce=0.40%-0.49%, surplus is that magnesium is with inevitable Impurity.This invention designs Sn, Ce content by rational composition, and takes suitable smelting technology, prepares the flat of regularity Row the second phase constitution, it is conducive to the damping capacity of alloy.By controlling alloying component and smelting technology in production technology, controlled The second phase morphology distribution in alloyage, can be effectively improved the damping capacity (SDC=41%) of alloy, and density is less than 2g/cm3. Present invention process is simple, portable strong, and low cost, easily operates, can be widely applied to national defence, civilian industry, to reach Lightweight and the effect of vibration and noise reducing, but its damping capacity is the most not ideal enough.
