The sell the handicraft aluminium alloy sample at reced prices and primitive sample of effectiveness for a given period of time has carried out the experiment a train of on to adopt a block of wood and strengthening to dissolve, function carrying out Mechanics pounding , coming ascertain the tensile test, the primitive sample on primitive sample first: Tensile strength sigmab, knuckles under intensity sigma0.2 , elongation rate dleta and pounds tenacity ak; Secondly, the sell the handicraft sample at reced prices and primitive sample of effectiveness for a given period of time carries out the measurement wearing the function experiment and Brinell hardness away on to dissolving course not strengthening together , comes to analyse comparison from this solid dissolve effectiveness for a given period of time handles the effect to 2014 aluminium alloy sample Mechanics functions and friction functions. The metallographic observing a sample organizes change , contrast , observe under metallographic microscope, analyse the come to reach a conclusion studying.

Experiment go into is indicated: Analysis but knowledges , 2014 aluminium alloys strengthens a course dissolving effectiveness for a given period of time handles the queen , existence compares complicated, the main alloy is each other: W looks at and appraises (Cu4Mg5Si4Al) , the theta looks at and appraises (CuAl2) , Mg2Si , CuMgAl2 , mixed sundries (FeMnSi) Al6 and Mg3SiAl2. 500 ~C strengthens classics dissolving , 165 ~C effectiveness for a given period of time handles the queen, polishing scratch is the most shallow , the amounts wearing away are minimal , abrasion resistance is best , the hardness is maximal when each other, 2014 aluminium alloys scatter trivial , homogeneous , wear away.

Population is strengthened as a matter of fact , through dissolving that effectiveness for a given period of time handles 2014 aluminium alloy of the queen separates more second phases out , uses whose abrasion resistance and surface hardness rise. With solid dissolve temperature rise, the resolving the alloying element is diffused is more sufficient , the place wrong density making base experience and observe metal increases by , distortion happened in the crystal lattice, the alloying element is able to change the solid solution coefficient of elasticity at the same time , that the molus , cohesive force and atom diffusing arrange a defect, makes the place wrong be changed into turn gleam , the material increasing , arousing place wrong motion resistance intensifies. 2014 aluminium alloys belong to precipitayion strengthen the type alloy , dissolving depending on strengthening mainly , come to intensify each other in effectiveness for a given period of time process from separating precipitayion out in oversaturation solid solution. Another is strengthened subsequently dissolving the temperature rises , the effectiveness for a given period of time queen is separated out each other increase by and homogeneous , peak value comes down , appears after the alloy intensity rises first.

Different solution to the aging process of the alloy specimen and the original sample for a series of experiments, first of all, the impact of the original sample, tensile test, to determine the mechanical properties of the original sample: tensile strength σb, yield strength σ0.2, δ elongation and impact toughness ak; followed through different solution to the aging process of the specimen and wear properties of the original sample tests and Brinell hardness measurement, the resulting solution to analyze the statute of limitations treatment on mechanical properties of 2014 aluminum alloy samples with the friction performance. Observed under the microscope in the metallographic specimen microstructure changes in contrast, observation and analysis of studies have concluded.
Experimental results show that: After analysis, we can see that the 2014 aluminum alloy after aging treatment solution, compared to the complexity of existence, the main phase alloy: W-phase (Cu4Mg5Si4Al), θ-phase (CuAl2), Mg2Si, CuMgAl2, inclusions (FeMnSi) Al6 and Mg3SiAl2. At 500 ℃ solution, 165 ℃ aging treatment, the distribution of alloy 2014 aluminum alloy small, uniform wear, the wear track the most shallow, the smallest amount of wear, wear the best, the highest hardness.
Overall, aging treatment after solid solution of aluminum alloy 2014 after the second phase precipitates more to improve the surface hardness and wear resistance. With the solution temperature increased, the proliferation of dissolved alloying elements more fully, so that the metal matrix increases the dislocation density, lattice distortion, and solid solution of alloying elements will change the elastic coefficient, diffusion coefficient, cohesion and atomic defects in order to make the dislocation line Variable bending, increase resistance to dislocation movement, causing the material to strengthen. 2014 aluminum alloy is precipitation strengthened type alloy, solid solution depends mainly on the limitation from the process of supersaturated solid solution precipitates in the precipitation to strengthen. In addition with the solid solution temperature, aging precipitates increased and uniform strength alloy increased first and then decreased, the peak appears.

To used the different melting aging treatment of metal craft the aluminum alloy test specimen and the primitive test specimen has carried on a series of experiments, first carried on the impact, the pulling test to the primitive test specimen, determined the primitive test specimen mechanics performance: Tensile strength σb, yield strength σ0.2, elongation ratio delta and impact tenacity ak; Next to passes through the different melting aging treatment of metal craft test specimen and the primitive test specimen carries on the attrition performance experiment and the Brinell hardness survey, from this analyzes the comparison melting aging treatment of metal to 2014 aluminum alloy sample mechanics performance and the friction performance influence.Observes the test specimen microstructure change under the metallography microscope, the contrast, the observation, the analysis research draws the conclusion.
The experimental study indicated that,May know after the analysis, after 2014 aluminum alloy melting aging treatment of metal, the existence quite complex, the main alloy is: W (Cu4Mg5Si4Al), theta (CuAl2), Mg2Si, CuMgAl2, inclusion (FeMnSi)Al6 and Mg3SiAl2.经500 ℃固溶、165 ℃时效处理后,2014 铝合金合金相分布细小、均匀，磨损时，磨痕最浅，磨损量最小，耐磨性最好，硬度最高。
The overall mentions, after the process melting aging treatment of metal 2014 aluminum alloy separation are more second, causes its resistance to wear and the skin hardness enhancement.随固溶温度提高,合金元素扩散溶解更充分,使基体金属的位错密度增加,晶格发生畸变,同时合金元素还会改变固溶体弹性系数,扩散系数、内聚力和原子排列缺陷,使位错线变弯,位错运动阻力增加,引起材料强化。2014 铝合金属于沉淀强化型合金,主要靠固溶、时效过程中从过饱和固溶体中析出沉淀相来强化。另外随着固溶温度升高,时效后析出相增多且均匀,合金强度先升高后下降,出现峰值。
