Stability and mechanical properties of some metastable austenitic steels [PDF]

Metallurgical Transactions, 1972
The relation between austenite stability and the tensile properties, as affected by testing temperature and processing, was studied for a series of alloys of increasing compositional complexity, viz., the Fe-Ni, Fe-Ni-C, and Fe-Ni-Cr-Mn-C systems. The “stress” and “strain induced” modes of transformation to martensite differed significantly in their ...

Characterization of a Medium Mn-Ni Steel Q&P Treated by a High Partitioning Temperature Cycle

Metals, 2022
In this work, a medium Mn-Ni steel was treated through Quenching and Partitioning (Q&P) with a partitioning temperature (PT) of 650 °C, which corresponded to the start of the austenite reverse transformation (ART) phenomenon.

Shape‐Memory Alloy Torsion Strips for Soft Robotic Manipulation and Morphing

Advanced Intelligent Systems, EarlyView.
In this research, a dedicated configuration of SMA strip is proposed for soft robotic manipulation and morphing. This configuration has broad application prospects and demonstrates remarkable advantages in soft body joint operations. Mimicking invertebrates, soft robots tend to control each of their body joints to achieve the desired shape changes and ...

Role of refined martensite microstructure and intercritical Mn partitioning on austenite reversion in Fe–5Mn-1.5Al-0.2C alloy

Journal of Materials Research and Technology
In this paper, we demonstrate a novel design to accelerate the austenite reversion of a Fe–5Mn-1.5Al-0.2C (wt.%) medium Mn steel (MMS), via a deliberating adding an elevated pre-annealing before conventional intercritical annealing.
