“…When the wear temperature decreased to −120 °C, the worn surface of both 304 ASS and 2205 DSS was smoother than those at 20 °C, and the dominant wear submechanism changed to cutting (Figure 8e,f). The enhanced TRIP effect of 304 ASS improved the hardness and sustained a constant toughness, [ 52 ] and the main cutting worn surface resulted in reduced weight loss and enhanced wear resistance. The worn surface of 2205 DSS became smooth because the fine grain size resulted in the maximum hardness and high toughness.…”

The sliding wear behaviors of three typical stainless steels with various microstructural characteristics, including 2205 duplex stainless steel (2205 DSS), 304 austenite stainless steel (304 ASS), and 430 ferritic stainless steel (430 FSS), were investigated at 20 °C and −120 °C to address wear failure under cryogenic environment conditions for applications such as spacecraft, polar exploration ships, and liquefied gas storage units. Results show that the wear resistance at 20 °C primarily depends on the initial hardness and strain hardening capacity, whereas toughness becomes increasingly important at −120 °C. The wear resistance of 2205 DSS is slightly higher than that of 304 ASS at 20 °C but much higher than that of 430 FSS. As the temperature decreases to −120 °C, the wear resistances of both 2205 DSS and 304 ASS improve owing to the enhanced hardness and favorable toughness endowed by fine grains and the stimulated transformation‐induced plasticity (TRIP) effect, respectively. By contrast, owing to the significant decrease in the toughness of 430 FSS, the worn surface delaminated and the wear resistance deteriorated. Therefore, the effect of toughness on the wear process is not negligible. This study provides guidance for the selection of wear‐resistant materials for different service temperatures.This article is protected by copyright. All rights reserved.

Mechanical properties and in vitro corrosion behavior of biodegradable Mg–0.5Zr–0.5Ca–xZn alloys in the simulated body fluid (SBF) solution are investigated. Zinc addition leads to a remarkable grain refinement in the as‐cast condition, as well as the formation of Ca2Mg6Zn3 and Mg7Zn3 compounds. As a result, the lean Mg–0.5Zr–0.5Ca–1Zn alloy shows the best combination of mechanical properties with an ultimate tensile strength (UTS) of 182 MPa, total elongation of 9.5%, and tensile toughness of 13 MJ m−3, which reveals ≈80%, 72%, and 190% improvements compared to those obtained for the Mg–0.5Zr–0.5Ca alloy, respectively. This sample also exhibits improved corrosion behavior, where a decrease in the corrosion current density (iCorr) is recorded via the addition of 1 wt% Zn. However, higher Zn additions result in the formation of a quasi‐continuous eutectic network with the consequent deterioration of tensile properties and increased effect of microgalvanic couples. The extreme grain refinement induced by the dynamic recrystallization (DRX) remarkably improves the overall mechanical properties of the hot extruded alloy but increased the iCorr. Accordingly, the properties of Mg–0.5Zr–0.5Ca alloys can be tailored for biomedical applications via Zn addition and thermomechanical processing.

“…Recently, investigations have been performed on AISI 304 L stainless steel to study the effect of grain size on mechanical properties as well as TRIP effect with the help of EBSD and XRD techniques. [108,109] Sun et al [110] conducted a study on metastable SS304 austenitic stainless steels involving EBSD analysis of annealed samples with varying grain sizes. The study is based on determining the austenite grain size using EBSD data and phase differentiation between austenite and martensite using color mapping difference between high angle grain boundaries and low angle grain boundaries by different colored lines.…”

Deformation‐induced austenite to martensite transformation is an important phenomenon that controls the flow behaviour of Transformation Induced Plasticity (TRIP) and TRIP‐assisted steels. Transformation kinetics and triggering strain are important parameters that need to be known during the transformation. Both these parameters can be correctly determined by an accurate quantitative assessment of the austenite during deformation. Various techniques have been employed for the quantitative assessment of the austenite by previous investigators. In this paper, both the in‐situ and ex‐situ measurement techniques used for quantitative assessment of austenite during/after tensile deformation of the TRIP and TRIP‐assisted steels are reviewed. A comparison of various techniques such as X‐ray diffraction, neutron diffraction, Mossbauer spectroscopy, and DC/AC magnetic permeability is presented. Due to the limited penetration power of the radiations, difficult access, and difficulty in setting up the measurement facility for the in‐situ measurements, X‐ray diffraction, neutron diffraction, and Mossbauer spectroscopy techniques do not yield accurate quantitative results and are time consuming. It is envisaged that an accurate quantitative assessment of austenite from the bulk of the TRIP and TRIP‐assisted steel specimens is possible with magnetic permeability measurement techniques. Real‐time quantitative assessments can be made by measuring changes in the magnetic permeability due to changes in the ferromagnetic content during deformation. Extensive calibration is required for the accurate measurement of the phases with the magnetic permeability measurements during the deformation of the steel.This article is protected by copyright.
