A lightweight shape-memory magnesium alloy | Science
A Mg-Sc alloy with both β and α phases has both a high ultimate tensile strength of 280 MPa and a large tensile elongation of ~30% at RT (). Moreover, a β-type Mg-Sc alloy shows an age hardening at ~200°C due to the formation of fine hcp (α) needles and/or plates in a β matrix and exhibits an extremely high hardness of ~230 Vickers pyramid nuer (HV) ( 16 ).

6105 aluminium alloy - Wikipedia
6105 aluminium alloy is an alloy in the wrought aluminium-magnesium-silicon family (6000 or 6xxx series). It is one of the least common of the alloys in this series. While most wrought aluminium alloys are covered by multiple standards (from any mixture of ASTM, EN, ISO, and national standard bodies), 6105 is only dealt with in ASTM B221: Standard Specifiion for Aluminum and Aluminum-Alloy
Comparison of compressive and tensile properties of …
1993/9/1· In particular, values of ultimate strength are consistently greater in compression than in tension, and the MMCs are considerably more ‘deformable’ in compression. However, irrespective of the type of test method employed, the MMC materials exhibit higher Young''s moduli, proof stresses, and ultimate strengths than the corresponding unreinforced materials, and much lower ductilities.

Mechanical Testing - Tensile Testing Part 2 - TWI
To approve a butt welding procedure most specifiions such as ISO 15614 and ASME IX require tensile tests to be carried out. These are generally cross joint (CJ) tensile tests of square or rectangular cross section that, as the name suggests, are oriented across the weld so that both parent metals, both heat affected zones (HAZs) and the weld metal itself are tested ( Fig.1 ).
