摘要
Deformation behavior Of Mo5Si3 was studied using single crystals under compression. It was found that yielding and flow behavior were strongly dependent on temperature, strain rate and crystal orientation. A stress exponent and an activation enthalpy of lower yield stresses were estimated to be approximate to 6 and 4.5 eV, respectively. (C) 2001 Acta Materialia Inc. Published by Elsevier Science Ltd.
