Did you know?
When a specimen of material is loaded in such a way that it extends it is said to be in tension. On the other hand, if the material compresses and shortens it is said to be in compression. On an atomic level, the molecules or atoms are forced apart when in tension whereas in compression they are forced together. Since atoms in solids alway… WebWe would like to show you a description here but the site won’t allow us.
WebCu-Ni-Si alloys are widely used in lead frames and vacuum devices due to their high electrical conductivity and strength. In this paper, a Cu-Ni-Co-Si-Cr-(Ce) alloy was prepared by vacuum induction melting. Hot compression tests of the Cu-Ni-Co-Si-Cr and Cu-Ni-Co-Si-Cr-Ce alloys were carried out using a Gleeble-1500 simulator at 500–900 °;C … WebJan 1, 2024 · A considerable rise in compressive strength of concrete having a 40% copper slag fraction when compared to control was also observed. However, compressive strength declined beyond 40% substitution as a result of excess free water and was lowest for 100% substitution. The tensile strength exhibited similar behavior to that of …
