A detailed mechanism of the HCP-FCC prismatic transformation is thus proposed in the present study to include the stages of slip, adjustment, and expansion. The energy change during each stage of the transformation will be calculated and compared with each other, in order to get a deep ...
Moreover, due to the elastic isotropy of Mg, it is argued that the distribution of the basal slip systems beneath the surface exclusively prescribe the measured pc. The role of temperature on the measured pc/E is clearly higher in the harder BCC metals than in the FCC and HCP metals (...
Crystal dynamics of the BCC-HCP martensitic transformation: II. Morphology was found an analytical dependence of the angle between the directions of close-packed atomic rows on the elastic properties of the initial bcc lattice. ... Kashchenko,MP,Chashchina,... - 《Phys Metals Metallogr Engl Tr...
In recent years, a series of in situ transmission electron microscopy (TEM) studies have been conducted in sequential slip transfer through GBs/interphase boundaries in FCC metals, hexagonal close-packed (HCP) metals and body-centered cubic (BCC) metals containing a variety of dislocations and ...
It was found that the nucleation and slip of some dislocations on the free surface were due to the FCC→BCC→HCP phase transition. At present, most of the researches on plastic deformation of magnesium alloys are at the micro-level. The room temperature deformation tests of AZ31 hot-rolled ...
Microstructurally sensitive fatigue crack growth in four material systems with BCC, FCC and HCP crystallography was investigated through integrated crystal plasticity eXtended Finite Element (XFEM) modelling and experiment. The mechanistic drivers for crack path tortuosity and propagation rate have been ...
