In this present work effect of temperature and graphite contents on the microstructural and mechanical properties of iron based powder metallurgy freeform was studied. The different graphite contents (0%, 2%, 5% and 10%) were mixed in iron powder and compact them in 100 KN. These specimens were sintered at 7000 C, 8500 C and 10000 C in muffle furnaces. Microstructural properties were evaluated ...
automotive and aerospace industries are required to light materials which have high properties. this causes to reduce production cost and fuel consumption. one of these advanced materials that have been attracted at these decades is particulate metal matrix nanocomposites. these materials have a combination of ductile matrix alloy properties and ceramic reinforcement nanoparticles. powder metal...
magnesium is potentially useful for orthopedic and cardiovascular applications. magnesium and its alloys are light, biodegradable, biocompatible metals that have promising applications as biomaterials. however, the corrosion rate of this metal is so high that its degradation occurs before the end of the healing process. one of the ways to improve the corrosion rate is to compose it with ceramic...
Light weight materials coupled to the need for cost-effective processing have combined to create a significant opportunity for aluminium powder metallurgy as its increasing interest. Aluminium alloy (AA 2219) metal matrix composite reinforced with multi walled carbon nanotube (MWCNT) produced by powder metallurgy (P/M) technique was analysed and CNTs dispersion were traced. The micro hardness a...
