STRUKTUR MIKRO CORAN KOMPOSIT Al 6061 + ABU BATUBARA SETELAH PERLAKUAN T6
Abstract
Heat treatment on the aluminum alloy is done by heating until a single
phase was then arrested a few moments and forwarded by rapid cooling to not
have time to change to another phase. If the material was left for a certain
period of time then there was the process of aging (aging). Changes will occur
in the form of precipitation (precipitation) The second phase begins with the
onset of nucleation and atom clusters that became the beginning of the
precipitates. This precipitates can increase the strength and hardness. This
process is the age hardening process called natural aging. If after rapid cooling
then heated again to below the solvus temperature (solvus line) then detained in
the long term and followed by slow cooling in the air called artificial aging
process (artificial aging). This study aims to determine the microstructure of
what is formed from a material with a temperature variation of aging (200oC,
225oC, 250oC) and holding time (8 hours, 12 hours, 16 hours) to determine how
much influence the variables, can be analyzed through testing SEM EDXA.
From the test results of SEM-EDXA it can be determined microstructure formed
in 6061 + Al composite coal bottom ash, which is composed of aluminum oxide
compound of Al 2 O 3 and MgO.
Keywords: microstructure, composites, coal bottom ash
