What are ceramics? The word ceramics is derived from the Greek word keramos which means ‘potter’s clay’. However, many compounds which are classified as ceramics today contain no clay. Modern Ceramics can be defined as the compounds of metals and non-metals. They generally have ionic atomic bonding between them. Traditional ceramics include insulating materials, glass, refractories,… Read More »
What is heat treatment? Heat treatment process is the controlled heating or cooling of plain carbon steel or alloy steel. Heat treatment of steel is done to change its molecular structure, in order to obtain certain mechanical properties. These mechanical properties could be hardness, strength or ductility. Various types of heat treatment processes are done… Read More »
