In conventional warm compaction, both powder and die are heated to a certain temperature during

compaction. This is a technique for producing P/M compacts with higher green and sintered strength as

compared ...

Powder metallurgy process was used in this work to produce NiTi specimens. Uniaxial compression, X-ray diffraction and differential scanning calorimetry were used for characterising the produced samples. L9 orthogonal arrays were chosen based...

Compressive mechanical test and numerical simulation via finite element modeling have been employed on closed-cell copper-matrix nanocomposite foams reinforced by alumina particles. The FE analysis purpose was to modelling ...

above this temperature for admixed powders, while it kept increasing for die wall lubrication.

Metallic hollow spheres are used as base materials in the manufacture of hollow sphere structures and metallic foams. In this study, steel hollow spheres were successfully manufactured using an advanced powder metallurgy technique. The spheres...

temperature on the pore morphology of

powder metallurgy 316L stainless steels. Porosity, dimension and morphology of the pores were

characterised by means of four basic parameters: fraction of surface porosity, equivalent circle...

Abstract

One of the important problems in powder metallurgy is to determine the time of sintering temperature or melting of materials and the time required to perform the reaction. They depend on several factors including the amount...
