Metallic rubber bounces back

Article Abstract:

The causes for certain types of metals exhibiting a quasi-elastic properties have been revealed by the experimental investigation of CuZnAl alloy by K.J. Tsuchiya and colleagues of Hokkaido University, Japan. Their investigation reveals that the martensitic and parent phase of the metal are involved in the quasi-elastic characteristics exhibited by the metal. The process of heating and tempering also provides a rubber-like elastic property to the metallic alloy.

Rapid alloy assessment

Article Abstract:

Combinatorial synthesis, or high-throughput screening, is a system used to synthesize and test certain properties of hundreds and thousands of very small samples of gradually changing composition. The system, introduced by drug companies to enable rapid assessment of possible new drugs, is now being used to assess structural materials, such as the superalloys used in jet engines.

Silicon self-analysis

Article Abstract:

The discovery that a high-energy grain boundary probably exists in simulated polycrystalline silicon is an exciting development in metallurgy research. Researchers Keblinski et al believe that the boundary layer is amorphous and in a state of thermodynamic equilibrium. Evidence suggests that the glassy material is distributed evenly alongside the bulk amorphous silicon material.
