Effect of sintering time on the apparent density and the final dimensions of the produced compact by technique metal powders


Abstract in English

In this search, has been studied set of practical experiences for compacting several metal powders composed a metallic alloy based iron from powders with a proposed geometric shapes (cylindrical). Several tests were done in order to reach the relationship between the final apparent density for the compact with a sintering time, and study changing the geometric dimensions of the final compact after the completion of sintering process during different time periods. The tests and Measurement results had been demonstrated that sintering time affect positively on the apparent density of the final compact which Manufactured by technique metal powders, and thus will increase its strength, where proportionality is directly proportional access even to a certain extent. And also its effect was an obvious shrinking diameters samples used in the tests. And changing (increase or decrease) in height samples. Search has shown the great importance of the follow-up studying and analyzing the relationships which associate that variables of metal powders technique each other, and their different effect on the final compact.
