General properties of kaolin geopolymers
(American Scientific Publishers, 2013-01)
This paper reported the properties of kaolin geopolymers in term of the bulk density, compressive strength, qualitative observation and SEM analysis of the kaolin geopolymers. Kaolin geopolymers were synthesized through ...
A comparative study of solder properties of Sn-0.7Cu lead-free solder fabricated via the powder metallurgy and casting methods
(Syscom 18 SRL, 2013-07)
The properties of Sn-0.7Cu solder bulk prepared via the powder metallurgy (PM) method were investigated and compared with solder bulk fabricated through casting. Distinct microstructures were observed in both PM and casting ...
Microstructure and interface analysis of glass particulate reinforced aluminum matrix composite
(Trans Tech Publications (TTP), 2013)
A characterization of microstructure and interface was made on the composites Al- 4% Cu reinforced with 15 wt. % glass particulate. The composite was fabricated by powder metallurgy followed by solution treatment and ...
Sintering behavior and microstructure evolution of mechanically alloyed W–bronze composite powders by two-step ball milling process
(Elsevier, 2013-01)
The miscibility of W in Sn and Cu is extremely poor. Sintering of W–bronze composites to their full density is proved to be difficult. To tackle this problem, the ball milling process of the W–bronze powder mixture proposed ...
On the structure of shape memory alloys
(Trans Tech Publications, 2013-12)
The paper presents the obtaining of shape memory alloys, base copper and a diffractometer and microscopic study on some samples. The study was made on CuZnAl samples, obtained by classic casting and educated. The shape ...
Properties of metakaolin geopolymeric binder
(American Scientific Publishers, 2013-01)
This paper investigates the physical and mechanical properties as well as the morphology study of the MK geopolymeric binder. Mixture of waterglass liquid and NaOH solution were used as the activator solution for the ...
Characteristics of Fe-yttria composites fabricated by powder metallurgy method
(Trans Tech Publications, 2013)
This study is focused on fabricating and characterizing iron (Fe) composites prepared by powder metallurgy route reinforced with varying weight of Yttria (Y2O3). Composites were prepared based on 5 wt. % to 15 wt. % of ...
The role of direct chilling, retrogression and reaging treatment on mechanical properties of high strength aluminum alloy
(Trans Tech Publications, 2013-03)
The effect of retrogression and reaging heat treatment on microstructure evolution andmechanical properties of 7075 Al alloy in direct chilling casting process was investigated. The subsequent heat treatment process comprised ...
