Abstract
The mechanical and structural properties were studied at room temperature
for Al-2wt.%Ag and Al-2wt.%Ag-1wt.%Sn alloys 503 K–583 K. The variation in the internal friction, Q-1,
dynamic Young's modulus, Y, Vickers hardness, Hv, and X-ray
diffraction patterns were obtained. For 533 K the internal friction
showed abrupt increase while Young's modulus and Vickers
hardness showed minima. The results showed a remarkable dependence of the
measured parameters on both Sn addition and the heat treatment regime.

| What is OpenURL? |
The OpenURL standard is a protocol for transmission of metadata describing the resource that you wish to access. An OpenURL link contains article metadata and directs it to the OpenURL server of your choice. The OpenURL server can provide access to the resource and also offer complementary services (specific search engine, export of references...). The OpenURL link can be generated by different means.
- If your librarian has set up your subscription with an OpenURL resolver, OpenURL links appear automatically on the abstract pages.
- You can define your own OpenURL resolver with your EDPS Account. In this case your choice will be given priority over that of your library.
- You can use an add-on for your browser (Firefox or I.E.) to display OpenURL links on a page (see http://www.openly.com/openurlref/). You should disable this module if you wish to use the OpenURL server that you or your library have defined.
