The article dealt with the technique on how to openly or directly examine the solidification procedure or the process of turning the metal alloy to solid state instantaneously through the use of x-rays. This study is being done by the National Aeronautics and Space Administration most widely known as NASA and the University of Alabama in Huntsville, Center for Materials Research.
The article actually discussed the things that can be seen during the investigation and how the method is executed as well as the strategy of the researchers in performing this study. The process of x-ray microscopy involves the utilization of microfocus x-ray source to generate figures or images of the solid and liquid interface at times of solidification phase under proscribed conditions. The characteristics that have dimensions lower than ten micrometers are scrutinized and analyzed in real-time. The results of this major research are intended to manufacture more heavy-duty alloys, and compound or combined substances. By the way, alloy is uniform in composition all throughout and known as homogenous mixture of two or more metals. This is actually a lower value of a metal due to addition of another substance. All kinds of researches and experiments are intended to uncover the earlier hidden or unnoticed realms.
The article also mentioned as an example, the aluminum-indium alloy micrograph. It tackled the captivating inside structures and compositions of the said alloy that can be viewed through x-ray microscopy. This is a medium intensification after solidification x-ray micrograph of an aluminum-indium monotectic alloy solidified in one direction, only from right to left, whereas the level of gravity was phasing up and down along the axis of the specimen from 1.8 to 0.01 multiplied with the earth gravity. This movement or activity is performed by flying in the air inside a NASA aircraft the heating system that produces the alloy. The activity is in a unique and parabolic course to imitate the low gravity state in space for twenty seconds at a time.
Moreover, the article also cited the significance of X-ray Transmission Microscope also known as XTM. The dispersal of the indium elements that develop in the course of solidification are sporadically collected in bands based on the level of gravity currently enforced. The diameter size of the specimen is five millimeters. The article also stated that at the moment the x-ray microscope is excessively huge to fly in microgravity surrounding. Nonetheless the X-ray Transmission Microscope or XTM is utilized to study flight specimens prior to and subsequent to the experimentations that are ran in a shuttle. The genuine importance of the X-ray Transmission Microscope is to investigate and discover the solidification phenomena as it occurs in real-time.
These kinds of studies or researches are beneficial to the infrastructure side of the economy as well as to improve the quality of metal alloys that can be used in order to erect buildings and other edifices that will be able to withstand the earthquakes and other calamities that may happen particularly in places that such calamities are frequently felt.
