WebFeb 7, 2024 · This paper proposes a new method for obtaining the rheological properties of solidifying alloys in the brittle temperature range (BTR). In that range, alloys show not only rheological, but also brittle behavior. Conventional methods to obtain rheological properties require steady state stress with ductility. Therefore, rheological properties of BTR alloys … Web2 days ago · Ge micropillars display remarkably temperature- and size-dependent deformation behavior during deformation. The mechanical properties of Ge micropillars are quite different than their bulk counterparts, as enhanced plasticity and increased strength are observed in the conventionally brittle temperature range (< 500°C, 0.64 T m). 17 …
