Cutting process by using abrasive saw produces millions of tiny sparkling particles
ripped apart from the original material. These particles are sent to fly in the air for a few
milliseconds before hitting a substrate. If remain untouched, this particles will be
collected as an aggregate on the surface of the substrate. It will gradually form a small
hill with some interesting characteristics to be studied further. So, in this project, the
author had studied the microstructure of the collected particles and learned about the
new mechanism of sintering inside the material. In order to achieve the objective, the
author cut the material into few parts. Then, the author mounted, grinded, polished and
etched each part of it. Then, the author studied the samples under optical microscope.
The author will also used Micro Vickers harness testing to check its mechanical
properties. From all these steps, the author managed to observe some of the steel
microstructure from it. The author also calculated the porosity of the material under
microscopy using scale approximation. The author was able to learn about new kind of
mechanism inside the material which will help us to understand more about sintering
process. As a conclusion, this project was based on research of new kind of mechanism
involved in this material. It is just a matter of time for us to unlock the secrets of this
technique, its mechanisms and the outcome from this procesS
