Evaluation to Combined Sintered Compact from Iron Powder Admixed with Fine Iron Powder and Micro Wax Powder by Flow Compaction.

Constitutive Equation for Powder Compaction Incorporating Powder Charecteristics

The increasing importance of powdered materials fabrication has led to an increasing emphasis on the understanding of the powder behavior during compaction. During compaction, a powder mass undergoes densification owing to various mechanisms, i.e. sliding, rotation, deformation and/or fracturing of the constituent particles. These densification mechanisms are very dependent upon the powder char...

Compaction of Commercially Pure Titanium Powder by Friction Powder Compaction Process

A new friction powder compaction (FPC) process is introduced for compacting commercially pure titanium powder. The FPC process is very simple and energy-efficient since it requires only a rotating tool plunged into an aluminum plate with a hole filled with titanium powder, and no external heat source is necessary. The sintering of the powder is mainly achieved by the friction heat and pressing ...

Reoxidation Rate of Sponge Iron Pellets, Briquettes and Iron Powder Compressed to Various Compressions in Air

The reoxidation rate of sponge iron pellets and briquettes and oxidation of pure iron powder with compressibility between 27% and 55% in air and within the temperature range 300-900°C has been investigated. Factors affecting the oxidation rate are presented. These include the effect of temperature, compressibility, and sintering of Fe-powder before and during the oxidation.

Mechanical Properties and Hardness Results of the Medium Frequency Induction Sintered Iron Based Powder Metal Bushings

In this study; iron based powder metal (PM) bushing compacts were sintered via medium frequency induction heating system. Iron based powders were mixed with 2 wt.% copper (Cu), 0.3 wt.% carbon (C) and 1 wt.% zinc stearat (Zn-st) via V-Type mixer. PM compacts were sintered by 2 different sintering processes. One of them was conventional sintering method other was medium frequency induction sinte...
