Tungsten and tantalum are neighbors in the Periodic Table of the Elements and, as refractory metals, both have very high melting points (tungsten: 3422C, tantalum: 2996C). However, the ductility of the two metals is quite different especially at comm... |
| EFFECTS OF GRAIN SIZE ON THE QUASI-STATIC MECHANICAL PROPERTIES OF ULTRAFINE-GRAINED AND NANOCRYSTALLINE TANTALUM |

The increase in strength due to the Hall-Petch effect, reduced strain hardening capacity, a reduced ductility, and changes in deformation mechanisms are all effects of reducing grain size (d) into the ultrafine-grained (UFG, 100 < d < 1000 nm) and na... |
| COMPRESSIVE BEHAVIOR OF BULK METALLIC GLASS UNDER DIFFERENT CONDITIONS —— COUPLED EFFECT OF TEMPERATURE AND STRAIN RATE |

Metallic glass was first reported in 1960 by rapid quenching of Au-Si alloys. But, due to the size limitation, this material did not attract remarkable interest until the development of bulk metallic glasses (BMGs) with specimen sizes in excess of 1 ... |
