Stored energy in metallic glasses due to strains within the elastic limit

Approaching the ideal elastic limit of metallic glasses

The ideal elastic limit is the upper bound to the stress and elastic strain a material can withstand. This intrinsic property has been widely studied for crystalline metals, both theoretically and experimentally. For metallic glasses, however, the ideal elastic limit remains poorly characterized and understood. Here we show that the elastic strain limit and the corresponding strength of submicr...

Metallic Foreign Body in the Lung Due to Gunshot Injury

A 37 - year- old man came to the hospital with a history of penetrating thoracoabdominal trauma due to gunshot wound in 10 days before. He underwent laparatomy and hepatorrhaphy in that time and right sided chest tube was inserted. Chest CT scan revealed metallic foreign body in lung tissue due to bullet burst. Right thoracotomy was performed and metallic foreign body extracted from lung tissue

Evaluation of the Elastic Properties of Bulk Metallic Glasses

The development of bulk metallic glasses as a prominent class of functional and structural materials has attracted considerable interest in the last years. One of the fundamental physical quantities necessary to describe the mechanical properties of the materials is the bulk modulus. In the present article, a simple method to estimate the bulk modulus and its pressure derivative is proposed. It...
