I have prepared magnesium green compacts from powders of different particle sizes. I observed that the green strength of compacts produced from fine powder was very low. Green compact splitted in two parts in the vertical plane during removal of green compact from the powder compaction dies. I repeated the experiment so many times and observed the same behavior. What can be the possible reason? Please explain.
Dear researchers,
I am working on Mg composites fabricated by powder metallurgy. I have investigated the wear behavior of Mg-based composites with variation in temperature. I observed that wear rate increased with an increase in the wear temperature. Can anyone explain me in detail, why is it happening? What is the mechanism? I am looking for your responses.
Thank you so much.
Asbestos is considered the best brake friction material because of its high thermal stability, low wear rate, low cost, etc. But, due to its carcinogenic effects, asbestos has been phased out. Now, asbestos-free braking materials are being developed. Today, non-asbestos organic (NAO) brake pads are being used widely. But, NAO brake pads have low thermal stability. So, the NAO type of brake pads is not suitable for heavy-duty applications. So, which materials are ideal for heavy-duty braking applications? Metal matrix composites? Carbon-carbon composites? Ceramic composites? or any other?
