Plastics are excellent materials with unique and very useful properties. You can produce just about anything you can imagine using plastics. Characteristics of Plastics History
For decades, battery storage technology has been a heavy weight on the back of scientific innovation. From cell phones to electric vehicles, our technological capabilities
If someone does a lot of arm curls at the gym, the typical result is that the bones and muscles in their arms will get
The coatings and paint industries strive to provide high technology coatings while reducing volatile organic compounds and energy consumption to produce a finished coating. Conventionally
As the standards of our industry rise due to increasing globalization and competition, there is an ever growing need for consistency and reliability. Breakdown of any unit, system or equipment is an avoidable and costly occurrence and must be prevented or minimized. Analysis of such failures becomes a resourceful and affordable tool in addressing such unwanted occurrences.
Why is XRD Important? It’s useful for studying Crystal structure. This method have the details about Grain size (or) Crystal size Orientation of the crystal, Cold worked, Distorted and Internally stressed crystals Re-Crystallization Preferred orientation etc
A crystalline material is one in which the atoms are situated in a repeating (or) periodic array over large atomic distances.
Non Crystalline Materials:
Materials that do not crystallize are called non-crystalline (or) Amorphous materials
Finishing Operations In Manufacturing
Repressing the sintered component in a die to meet required tolerances.
Repressing the sintered component in a die to increase the density and to give additional strength.
What is sintering in powder metallurgy process?
The operation of heating the green compact at high temperature in a controlled atmosphere (Reducing atmosphere which protects oxidation of metal powders). The Sintering increases the bond between the particles and therefore strengthens a powder metal compact. Sintering temperature and time of sintering depends on the type of powders and the strength required in a final product. The Sintering temperatures usually 0.6 to 0.8 times the melting point of powders.
