“…Studies reported by Mondal 24 presented the fitting curves of Hollomon, Swift and Voce for AFNOR 15CDV6 steel material. The model Voce described adequately the tensile flow behavior of the 15CDV6 steel subjected to cold deformation The author also described the Voce model as being ideal for strength prediction, with its parameters correlated with 0.2% YS and UTS with similar slopes.…”

Maraging steels are ferrous alloys with Ni, Co, Mo, and Ti additions. These materials are a special class of ultra high mechanical strength steels with wide and special applications in strategic areas, which makes their knowledge very valuable. Computational advances allowed to analyze the behavior of these materials numerically, using the finite element method and developing mathematical models that can represent numerically its mechanical behavior. The present work has the objective of surveying the mechanical properties of maraging steels 300 and 350 by slow strain rate tensile (SSRT) tests, after the solution treatment at 1183K for 1h. Additionally, it was evaluated the hydrogen embrittlement in samples tested by SSRT under cathodic protection with a potential -1.2 VSCE in 3.5% NaCl solution.The study was complemented with detailed fractographic analysis. This work also presents the analysis of representative models by use of Hollomon, Swift, Voce and coupled Swift-Voce equations to describe the strain-hardening behavior. Compared to the others, the Voce's model was the one which best fitted the experimental results, with values of R 2 higher than 0.992. Through the variation of the chemical composition found in the different grades of maraging steels, this work contemplates the creation of a generalized Voce model based on the variation of the Ti content. The work concludes presenting the generalized Voce model proposed and a numerical analysis of the SSRT results with a good accuracy of the strain-hardening response.

“…Effect of preform heat treatment on flow formability and mechanical properties has been investigated for AISI4340 steel by Podder et al [5]. Influences of cold deformation on room temperature tensile stress-strain behaviour have been evaluated by Mondal et al for AFNOR 15CDV6 steel [6]. Although the mechanics of the process is reasonably well understood, there is a lack of the literature on effect of post flow forming heat treatment operation on resultant mechanical properties of flow-formed Al alloy shells.…”

The present study reports the effect of the heat treatment on the tensile properties of the reverse flow-formed AA6082 Aluminum alloy tube. Tensile specimens obtained after each forming pass have been subjected to three different heat-treatment conditions viz., as-flow formed (AFF), as-flow formed followed by artificial aging (170°C/6h) and HT (solutionizing + 170°C/6h) treatments. Characterization of the tensile properties reveals that as-flow formed condition (followed by natural aging) gives the best combination of yield strength, UTS and percentage of elongation. The variations in tensile properties are correlated with microstructure of the materials.
