2、i , C. Muthukumaaran , I. Anish Hilary Abstract Die design is one of the most important steps in Powder Metallurgy process because the shape and attributes of the die will directly affect the final component. Die design has a number of steps and considerations to be made before fabrication. This pro

3、ject is an attempt to design and fabricate a die for cold compaction process used in the powder metallurgy process. This project includes design and fabrication of a die for the fabrication of a rectangular specimen, which used to test the impact strength of the specimen using Izod impact test and C

4、harpy impact test. The die is designed according to the standards of ASTM B925 with the die being made of AISI D3 tool steel with the punch material being AISI D2 steel. This project also includes the design considerations, calculations, 2-D drawings, 3-D model and processes involved in fabrication

Introduction Powder metallurgy is the process of blending fine powdered materials, pressing them

6、 into a desired shape or form, and then heating the compressed material in a controlled atmosphere to bond the material. Powder Metallurgy is a continually and rapidly evolving technology embracing most metallic and alloy materials, and a wide variety of shapes. Al-Qureshi et.al 1 achieved full densification by several routes and often involves the simultaneous application of stress and temperature to close residual pores. This is achieved through cold and hot forging or extrusion processe
