【 摘 要 】

Bronze has widely use in industry as a material for gear, propeller, and others. These products can be produced by powder metallurgy technique via compacting and sintering process. To improve green strength of the green compacted can be done with the warm compaction process. This work aimed to study the optimalization warm compaction parameters such as compacting temperature, compacting pressure, particle size, and particle content when the porosity and hardness of tin ore waste reinforced bronze matrix composites are simultaneous considered. The combination of signal to noise ratio approach in Taguchi method and grey relational analysis was used to evaluate multi responses of composites. The quality characteristic of responses are smaller the better and larger the better. It was found that, the optimal parameter setting is compacting pressure factor at 400 Mpa, compacting temperature is at 350°C, particle size is at 80 μm, and particle content is at 12 % weight.
