This book was released on 2010 with total page 61 pages. Available in PDF, EPUB and Kindle. Book excerpt: This project is to investigate mechanical properties and microstructure of aluminium silicon alloy using sand casting. In this project there were separated into two parts which are foundry laboratory and inspection parameter. In foundry laboratory, a sand casting process was performed by using a diesel furnace to melt the raw material. Then, determinate an optimization of mass degassing agent added in the casting aluminium silicon alloy is to remove the hydrogen element in the casting product. After the casting process, an inspection parameter was performed to investigate the mechanical properties (tensile strength and hardness) and microstructure changed of the aluminium silicon alloys. From the observation of the result, a modified alloys exits slightly higher hardness values than non-modified. Since the coarseness of porosity is proportional to grain size, porosity in fine grained casting is finer and less harmful in fine-grained casting. In additional, shrinkage and hot cracking are usually associated with coarse-grained structure. So, a finer grain size minimizes shrinkage and the mechanical properties, such as tensile is better for fine grained casting than coarse-grained casting. The modified of the casting product by adding the degassing agent inside the casting will give better result mechanical properties in hardness test and tensile strength until an optimization point achieved where there is improvement of mechanical properties.

Download or read book Effect of Precipitate Hardening Treatment on Microstructure and Mechanical Properties of Cast Aluminum Silicon Alloy (A356) written by Benjunior Bindamin and published by . This book was released on 2012 with total page 57 pages. Available in PDF, EPUB and Kindle. Book excerpt: The main objective of this work was to study the influence of the precipitate hardening treatment of the A356 aluminum silicon sand cast alloy. The experiment process was separated into three parts which was foundry laboratory, material laboratory, and inspection. In the foundry laboratory, the cast alloys was prepared by sand casting process and was melted in a diesel furnace. In the material laboratory, the casting was then treated with precipitate hardening treatment and followed by machining. The inspection was done to observe microstructure, tensile properties and hardness properties. The effect of the solution heat treatment and artificial aging holding time on the microstructure, tensile properties, and hardness properties of the alloy was analyzed. Three specimens were heat treated with a solution treatment at a same temperature of 540°C, was quenched in room temperature water followed by artificial aging at a same temperature of 170°C. The different parameters were holding times which were solution at 2 hours and aging 2 hours, solution at 2 hours and aging 6 hours, solution 6 hours and aging 6 hours. The microstructure were investigated and tested by optical microscope, tension test and Rockwell hardness test respectively. The result found was at 2 hours solution of 540 °C homogenization and saturation of magnesium and silicon in Į(Al) phase, spheroid of eutectic Si phase occurred. After solution treatment, 2 hours artificial aging at 170 °C produced hardening precipitates. Samples treated at 6 hours solution and 6 hours artificial aging achieved even higher tensile strength and hardness. The increased of holding time for solution and artificial aging increased precipitate hardening.

This book was released on 2018-07-20 with total page 67 pages. Available in PDF, EPUB and Kindle. Book excerpt: In a metal matrix composite material an Al alloy is taken as metal matrix reinforcing with different type of reinforcing material like SiC, fly ash, Red mud etc in order to prepare different samples for testing different mechanical properties like hardness test, impact strength, tensile strength along with its wear behaviour, electrical conductivity so that it can be applied for better applications if the outcome shows improvement in the properties. The present research examine the mechanical properties and microstructure of aluminium alloy 63401 metal matrix composite reinforced with silicon carbide powder of different wt % i.e. 3%, 6% and 9% and different grain size. Conducted the experiment by keeping the SiC grain size constant at 74 μm, 149μm and 177 μm and varied the SiC weight %. The mechanical properties i.e., hardness, tensile strength and impact strength were studied by preparing the desired samples by stir casting method. From the obtained results we found that more the weight percentage of SiC powder, hardness, impact strength and tensile strength increases. The percentage elongation decreases with increase in weight percentage of SiC and increases with decrease in grain size of SiC. Also microstructure shows the nearly distribution of reinforcement material.

Download or read book Design of Advanced Aluminum Silicon Alloy Compositions and Processing written by Xiao Li and published by . This book was released on 1996 with total page 346 pages. Available in PDF, EPUB and Kindle. Book excerpt: Part I discusses the development of an aluminum-magnesium-silicon alloy that may combine strength, extrudability, favorable corrosion resistance with low cost and scrap compatibility. The first part of the study determined the effects of small composition, heat treatment and mechanical processing changes on the ambient temperature tensile properties of the alloy. A combination of magnesium and silicon of about 2%, 1% copper, 0.2% chromium and 0.1% vanadium can produce a T6 alloy with significant higher strength, fatigue and corrosion fatigue properties for both ingot and extrusion than those of 6061 but with only a modest increase in cost. The new alloy has been designated as AA6069. The second part of the study determined the T6 properties of 6069 alloy. The tensile test results of cold and hot extrusions of hollow, solid bars, and high pressure cylinders indicate that the T6 properties ranged from 55-70 ksi (380-490 MPa) UTS, 50-65 ksi (345-450 MPa) yield strength, and 10-18% elongation. It also appears that the fracture toughness and general corrosion resistance in saline environment are comparable or better than those of 6061 T6. Part II attempted to evaluate the formation, formability, thermal and mechanical properties of semi-solid A356, A357 and modified aluminum silicon semi-solid alloys. The semi-solid alloy microstructure was produced in this study by purely thermal treatment rather than conventional and expensive electromagnetic or mechanical stirring. Three heat-up stages in semi-solid treatment were evaluated. Stage I is related to the heating of the alloy in the solid state. Stage II is related to the eutectic reaction. Stage III is related to the heating of the semi-solid slurry. Stage II requires the longest time of the three heat-up stages due to the endothermic reaction on heating. An increase of furnace temperature can greatly reduce the time of stage II. The atmosphere (vacuum, air, argon) of the semi-solid treatment does not appear to greatly affect the T6 properties of semi-solid alloys. The microstructure and T6 properties of semi-solid A356 do not appear sensitive to the homogenization treatments before semi-solid treatment. The porosity of semi-solid ingots and pressed parts increases as the cooling rate decreases in unformed and subsequent-to-moderate pressure forming. The T6 properties basically appear sensitive to voids, with a degradation of properties as the void concentration increases. The formability of A357 may be improved as the spheroidal particle size decreases. Hence, formability may improve with decreasing ingot grain size. The mechanism of coarsening of the solid phase at isothermal temperatures is related to Ostwald ripening and/or "merging" of particles. The mechanical properties of die-casting parts show that the method of thermal treatment to produce a spheroidal microstructure is an effective method for industrial production of semi-solid aluminum-silicon alloys.
