Editors: Y. Yokoyama K. Fujita A. R. Yavari A. Inoue Publisher: Taylor & Francis Pages: 14 ISBN: Abstract: A new bulk glassy alloy (BGA) showing macroscopic tensile plastic elongation at room temperature has been developed in the hypoeutectic Zr–Ni–Cu–Al alloy system. The hypoeutectic Zr–Ni–Cu–Al BGA shows a high Poisson’s ratio, a low Young’s modulus, and is highly malleable in compression. It exhibits a Poisson’s ratio of 0.39, a Young’s modulus of 73 GPa, and a distinct tensile plastic elongation of about 1.7% at room temperature with necking due to the operation of many shear bands. The tensile plastic deformability seems to originate from modifications of the glass structure with increasing the number of Zr–Zr atomic pairs in the hypoeutectic composition. 本资源2.18 MB。 ---------------------------------------------------------------------------- Malleable hypoeutectic Zr–Ni–Cu–Al bulk glassy alloys with tensile plastic elongation at room temperature.pdf ---------------------------------------------------------------------------- |
