Abstract

Because of some special properties such as high melting point and hardness manufacturing of TUNGSTEN parts is very difficult by some processes such as machining, casting, etc. An alternative method for making these parts is POWDER METALLURGY technique. Because of some limits in POWDER METALLURGY technique the EXPLOSIVE COMPACTION method was applied for compaction of TUNGSTEN powder. At first the POWDER METALLURGY and EXPLOSIVE COMPACTION processes were explained in this paper. Already, these two methods were applied for manufacturing of several samples using TUNGSTEN powder. All of samples have a cylindrical shape with 3 mm length and 20 mm diameter. In order to compare the mechanical and metallurgical properties of these samples, the density and hardness were determined and fracture surface of cross sectional area of them were analyzed by scanning electron microscope (SEM). The results indicated that the higher density (10% higher) and hardness (75% higher) for TUNGSTEN products can be obtained by EXPLOSIVE COMPACTION method.
