Experimental Investigation of Effective Parameters at Laser Sintering the Mixture of Iron and Copper Powder
Optimization of process parameter is one of the ideal goals in laser sintering. The results of this process were measured as output parameters like: density, micro hardening, macro hardening, tension, roughness, stiffness, balling. In this paper, the influence of input parameter such as laser power, scan speed, material powder and etc are surveyed on output parameter like balling affection and ...

متن کاملStudy of Graphite Content and Sintering Temperature on Microstructure Properties of Iron-Based Powder Preform
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 ...
متن کاملThe Role of Particle Size on the Laser Sintering of Iron Powder
The effects of powder particle size on the densification and microstructure of iron powder in the direct laser sintering process were investigated. Iron powders with particle sizes ranging from 10 to 200 m were used. It was found that the sintered density increases as the laser energy input is increased. There is, however, a saturation level at which higher density cannot be obtained even at ve...
