Design, fabrication and analysis of compaction die for powder processing

Abstract

Abstract A compaction die has an essential role in the powder metallurgy process due to the controlling and ease of processing. The shape and properties of die can significantly affect the features of the final part as the several steps and assessments are involved before design and fabrication of compaction die. This work is an effort to design and manufacture a compaction die that can successfully use for uni-axial compaction of NiTi powder. The design and development of die includes design consideration, 2D drawing, 3D model and processes involved in the fabrication of die. The die design was analyzed by ANSYS 19.1 software in a simulated environment, and the fabricated die was tested experimentally by preparing the composite sample successfully at 1000MPa compaction pressure using universal testing machine. Further, the compaction behaviour, density, compressive strength and hardness of developed NiTi composite have also evaluated.
