Thermal analysis was performed to determine the solidification behavior and nature of alloy of the melt during its solidification. It revealed the variation in the nature of alloy due to the variations in eutectic freezing and carbon equivalent of the melt. The obtained thermal parameters from the thermal analysis were further used for the casting ...

The article attempts to explore the new processing technology for direct manufacturing of lightweight austempered ductile iron (ADI) casting in a permanent mold. The new processing technology is based on the innovative integrated approach toward casting and heat-treatment process. In this technology, the ductile iron samples obtained ...

However, for environmental and economic reasons, recent research in industry and academia has sought ways to reduce the use of machining fluids. This paper reports the use of dry and minimum quantity lubrication (MQL) to drill austempered ductile iron (ADI), a new class of materials used for light weight automotive components like connecting rods and crankshafts. In this study, ADI is produced by a novel processing technique known as continuous castingheat treatment process. The novel technique is developed by the integration of casting (in die casting) and heat treatment processes in the foundry to save energy and time. This paper deals with an experimental investigation on the role of MQL drilling on the cutting forces, tool wear and surface roughness of newly produced ADI at industrial speed-feed combinations by TiAlN-coated tungsten carbide tool. MQL drilling, performance is then compared with the dry and conventional drilling process under the same experimental conditions and environment. The results include significant reduction in tool wear, cutting forces and surface roughness by MQL drilling, mainly through reduction in the cutting zone temperature.

The green ADI grade was produced by a novel manufacturing technology known as continuous casting-heat treatment technology to save energy and time in foundry. However, in spite of good combination of strength, toughness and enhanced wear resistance, the microstructural properties of ADI sometimes lead to machinability issues. The effect of cutting parameters on cutting force ...

The green ADI grade is produced by a new processing technology known as continuous casting‐heat treatment process. The effect of coatings on tool wear and surface finish of the holes when drilling using coolant were reported. Results showed that the tool with post‐coated coating has higher anti‐friction properties as compared to PVD‐TiAlN ...

ADI is characterized by improved mechanical properties but has low machinability as compared to other cast irons and steel of similar strength. The novel technique is developed by the integration of casting (in die casting) and heat treatment processes in foundry to save cost energy and time. Specimens just after casting were ...

Ils peuvent être réduits, dans une certaine mesure, par le développement soit d'un matériau de fonction ou par la mise en œuvre d'un nouveau processus de fabrication éco-durable. Dans cette optique, l'émergence récente de fonte" bainitique"(ADI-Austempered Ductile Iron-) peut être considéré comme un saut technologique important répondant à la demande croissante ...
