- 摘要：Influence of Ni and Mn for Al Si Cu Mg series alloy on the microstructure and wear failure mechanism under twin body wear condition was studied through the wear resistance test by means of fast wear tester in connection with the micro constituent, the images, optical microscope and SEM analysis. The wear failure mechanism of Al Si Cu Mg series alloy is composed of the plough wear and the peeling of surface layer under twin body dry friction condition. Al 34 Cu 28 Ni 38 compound is formed in the microstructure of Al Si Cu Mg series alloy and the surface layer peeling is the main wear failure mechanism with alloying element Ni addition. Al 56 Si 4Cu 9Ni 26 Mn 5 compound is formed in the microstructure and the plough wear is the main wear failure with Mn and Ni addition.关键词：Aluminum Alloy;Microstructure;Twin body Wear;Wear Mechanism

发布时间：2023-12-18 - 摘要：The characteristics of the microstructure and the strength properties of aluminum matrix composites reinforced with γ Al 2O 3 long fibre, δ Al 2O 3 chopped fibre or SiC particulate by die casting infiltration technique was studied. It is shown that Al matrix composites with high filtration quality and heat treated ability could be prepared with industrial die casting machine through the optimization of process condition. The composites, having ideal process quality、microstructure and strength properties up to or over prediction value by mixture law, are similar to those with 130 MPa tensile strength by squeezing infiltration technique.关键词：Die Casting;Composite;Pressurised Infiltration;Microstructure

发布时间：2023-12-18 - 摘要：The preparation and die casting process of semi solid billets of aluminum alloys A357,ZL108 and AS9U3 for motor parts were studied. The characteristics of semi solid non dendritic microstructure of the three kinds of aluminum alloy were compared by experimental analysis. The results show that the microstructure of semi solid billets of prepared A357 aluminum alloy is quite similar to those of billets produced by foreign professional provider of semi solid billets but the microstructures of ZL108 and AS9U3 are obviously different from those of A357 alloys. With the optimization of semi solid die casting process, three kinds of high quality motor parts were manufactured successfully.关键词：Semi solid;A357 Alloy;ZL108 Alloy;AS9U3 Alloy;Die Casting

发布时间：2023-12-18 - 摘要：The hard spot area in aluminum alloy die casting mainly originates from the primary silicon and AlSiMnFe intermetallic compound. The primary silicon and Fe phase can not be refined with conventional sodium salt modification. Specially prepared RE almoy with a definite ratio of La, Ce, Pr, Nd and Yb not only can refine eutectic silicon but also refine primary silicon less than 10μm in size and improve morphology of Fe phase, so the hard spot area in aluminum alloy die casting could be eliminated effectively.关键词：Hard Spots;RE Alloy;Modification
