Abstract

Strength, toughness, machinability and damping capacity are properties of compacted graphite iron that distinguish the properties between flake graphite cast iron and spheroidal cast iron. The formation of compacted graphite can be set to achieve the required specification. The formation of compacted graphite is started from spheroidal to compacted cast iron. The residual magnesium after magnesium treatment and the solidification rate have a significant role in the formation of compacted graphite. The high content of residual magnesium can obstruct the graphite plane to grow during the transformation from spheroidal to compacted shape. In addition, the cooling rate of the casting can be controlled by varying the casting thickness. The compacted graphite in the cast iron are characterized according to shape, size and distribution. The optimum compacted graphite in the cast iron that can be produced has 30 mm of casting thickness with 0.017 % of residual magnesium.

Abstract

Indonesia is one of the countries with a high level of natural disaster vulnerability, so a good disaster mitigation process is needed. Amphibious Articulated All Terrain Vehicle (AAATV) is designed as one of the solutions to the difficulty of the mitigation process. Amphibious Articulated All Terrain Vehicle is a vehicle with special capabilities that are able to pass through various terrains. Amphibious Articulated All Terrain Vehicle consists of several systems, one of which is the propulsion system. In the Amphibious Articulated All Terrain Vehicle drive system, there is one sub-system, namely the transmission gearbox. This design process uses the VDI 2222 methodology. The design and validation process uses SOLIDWORKS and KISSsoft software. From the design results, it is found that the vehicle will use a Kubota V2203 type diesel engine with a power of 36.4 kW. The desired speed variation is achieved with values of 9.85 km/h, 19.34 km/h, 39.64 km/h, and 10.04 km/h. The design weight is 58.73 kg with dimensions of 346.1 mm x 260 x 347 mm

Abstract

The effective use of cutting tools such as carbide inserts is crucial in the manufacturing industry, especially in machining processes involving hard materials. Carbide inserts are a type of cutting tool used to cut materials in machining processes. This research aims to discuss the experiment of producing carbide insert test specimens using the powder metallurgy technology process and made from Metal Matrix Composite material. The research method employed is the design of experiments with the Taguchi method. The controlled parameters are Fe (%), namely Binder (%), and mixing time (minutes). The response measured is the hardness value (HV). The contribution of the process parameters influencing the response value is found to be Fe = 11.90%, Binder = 54.70%, and mixing time = 30.99%. The experimental results yield a hardness value of 1534.778 HV. In conclusion, the most influential parameter in carbide insert production through powder metallurgy technology is the Binder (%) with a contribution of 54.70%.
