“…1 (d). In contrast to the other work showing both upper and lower yield stress with a large Lü ders strain [10,31,32], the engineering stress-strain curve of the studied material tested in air at a strain rate of 10 À3 s À1 exhibits a continues yielding and pronounced strain hardening as presented in Fig. 1 (e).…”

Mechanical properties and deformation behavior have been studied in two hot-rolled 0.2C-1.5Al-8.5Mn-Fe (1.5Al steel) and 0.2C-3Al-8.5Mn-Fe (3Al steel) transformation induced plasticity (TRIP) steels, subjected to an optimized quenching and tempering (Q&T) treatment. The study indicated that 1.5Al steel was characterized by excellent combination of ultimate tensile strength (UTS) of 1373 MPa, tensile elongation (TE) of 31.8%, and UTS×TE of 43.6 GPa%, where the superior mechanical properties are mainly attributed to the discontinuous TRIP effect. In contrast, 3Al steel indicated lower UTS, but higher TE of 34.5%, which resulted from the discontinuous TRIP effect and the cooperative deformation of δ-ferrite. The discontinuous TRIP effect is a consequence of varying degree of stability of austenite, which results from different austenite grain size, non-uniform C-content and Mn-distribution in lath-like austenite and blocky austenite.

“…The XRD spectral analysis of ART‐annealed samples for 60 min at 750 °C after tensile test in Figure shows that the austenite peak intensities of γ (311) and γ (200) are significantly reduced, this implies that partial retained austenite is transformed to martensite during tensile test. Meanwhile, it is realized that {111} γ intensity barely diminishes, implying that the {111} oriented austenite is much harder to induce to martensitic transformation . And the preferential martensite transformation of {200} and {311} crystal planes of the austenite had been verified by the previous studies .…”

The effects of annealing conditions on the microstructure and deformation mechanism of 0.17C-9Mn-3.5Al steel have been investigated. Through austenite reverted transformation (ART) annealing, a multiphase microstructure composed of d-ferrite, a-intercritical ferrite, g-austenite, and a'-martensite is obtained in as-forged specimens. For the specimen annealed at 750 8C for 60 min, a high volume fraction (42.19%) of retained austenite is attained, yielding a large total elongation (TE) of %38% and tensile strength (Rm) of %810 MPa and a two-stages work hardening behavior. The work hardening behavior analysis using the differential C-J model clarifies that the multistage can be mainly attributed to the discontinuous transformation induced plasticity (TRIP) effect, which is related to the volume fraction of retained austenite and its different stability levels as well as cooperative deformation of the multiphase microstructure. Thus, the active TRIP effect predominately affects the high strain stage, resulting in a higher work hardening ability and a increased plasticity.[ Ã ] X.
