“…As compared with steels, graphite ductile irons have excellent castability, machinability, vibration absorption and low cost [16][17][18]. Graphite ductile irons have been commonly utilized in many industries such as automobiles (Crankshafts, Camshafts), infrastructure construction (Manhole cover) and agriculture tools (Plough shares, Digger Teeth) [19][20][21][22][23]. As-cast graphite ductile iron is directly engaged in the manufacturing of products sometimes.…”

The current research describes the preparation of nanoparticle-reinforced ductile iron specimens through an aluminum master alloy containing bi-phase TiC-TiB2 nanoparticles. The pearlitic structure, hardness and wear resistance were examined and compared for ductile iron specimens with and without nanoparticles. It was found that the presence of a small amount of TiC-TiB2 nanoparticles could refine the lamellar structure of pearlite, increase the hardness and lower the wear loss under dry and lubricated test conditions. Adhesion with plastic flow, material removal and material smearing were reduced on the wear track which was associated with the coupled effects of finer pearlite and higher hardness after engaging the TiC-TiB2 nanoparticles. In addition, it was found that the nanoparticles were distributed on the worn areas, which could withstand the normal load and minimize the contact between the ductile iron substrate and counterface during the wear tests.

“…ADI adalah besi cor yang memiliki grafit bulat yang diperoleh melalui proses isothermal heat treatment. Sifat mekanik yang baik dari ADI disebabkan karena adanya struktur ausferritic yang mengandung ferit (acicular ferrite) dan karbon jenuh pada austenit [6][7] dan sifat mekanik yang diperoleh juga tergantung pada parameter perlakuan panas, ukuran dan distribusi grafit bulat yang ada, struktur mikro yang dihasilkan dan ada atau tidaknya cacat yang dihasilkan selama proses pengecoran berlangsung [8][9].…”

Pengaruh Parameter Proses Milling pada Austempered Ductile Iron (ADI) Terhadap Kekasaran Permukaan Benda Kerja dan Chip Thickness Ratio

Austempered ductile iron (ADI) is a difficult material for machining, even though ADI is believed to have several advantages such as strength, ductility, high toughness, fatigue resistance, good dynamic wear resistance, has a good strength-to-weight ratio, easy to manufacture and easy to cast that causes it to be widely used in various applications. This study investigates the effect of milling parameters on surface rougness and chip thickness ratio on milling of ADI. To produce ADI, ductile irons were first austenitized in furnace at 900oC for 1 hour and then they were quenched in salt bath at 375oC for 1 hour. The work material was machined with uncoated carbide tool. The tool was 20 mm in diameter. The cutting experiments were carried out in the dry mode. The feed was varied from 0.05 to 0.1 mm/tooth for cutting speed ranging from 15 m/min to 25 mm/min and depth of cut ranging from 0.1 mm to 0.3 mm. The surface roughness was measured using the Mitutoyo SJ-201, surface roughness machine. The chip thickness was measured using software Image J from the photograph produced by digital microscope endoscope. The results show that connected and loose chips were produced. Long and continuous chips were not found in this study. The effects of cutting speeds, feeds and depth of cut on surface roughness and chip thickness ratio are reported in this paper
