“…Temperature rise with an increase in strain rate induces stabilization of the austenitic phase. Thus, the condition prevents further martensitic evolution Murr et al 1982;Nanga et al 2009;Talonen et al 2014).…”

“…However, the adiabatic heating at high strain rate results in lower martensite content at strain above 0.25 as above-mentioned. Talonen et al (2014) and Nanga et al (2009) studied the effect of strain rate on martensitic transformation in type 301LN stainless steel over a range of strain rate from 3 × 10 −4 to 200 s −1 . Both authors reported that increasing the strain rate halts the martensite transformation because of stabilizing austenite.…”

Among various materials used for structures, TRIP steel has attracted the interest of the scientific community because TRIP steel indicates better performances such as formability, toughness and energy absorption as well as strength and ductility than other kinds of advanced high strength steel because of strain-induced martensitic transformation. From a microstructural point of view, two mechanisms are usually considered to explain the high performances: the Magee and the Greenwood-Johnson effects: however, it has not been proven yet. On the other hand, even though TRIP steel shows the excellent energy absorption under the high-speed deformation, the amount of martensite is very small by an influence of the heat generation with plastic transformation. In order to solve this paradox and explain macroscopic performances from the microscopic deformation mechanism, a concept of a spatio-temporal multiscale should be introduced. In this paper, research works done by the one of the authors on the mechanism of high functionalization in TRIP steel from the viewpoint of a spatio-temporal hierarchy are summarized with reviewing some related papers.

“…The outcomes of this study show that thermal and mechanical stabilities are correlated to the fluctuations of carbon concentration over various austenite grains. Nanga et al [14] conducted uniaxial tension, shear and deep drawing tests on two grades of austenitic stainless steels, AISI 301LN and AISI 201, over a temperature range of −150 • C to +150 • C and strain rate range of 3 × 10 −4 s −1 and 200 s −1 . The experimental results confirm a decrease in martensitic transformation with temperature rise.…”

“…DeMania reported that martensite content in 304L stainless steel sheet specimens that were subjected to uniaxial tension was higher than one in plane strain tension at −40 °C. Nanga et al studied the two types of stainless steel sheets and indicated that the highest phase transformation occurs under equibiaxial tension and uniaxial tension, followed by plane strain tension and shear loading. Beese and Mohr expanded on the model of Santacreu et al to perform some experiments on stainless steel 301LN sheets to find that the kinetics of phase transformation depends not only on the stress triaxiality, but also on the Lode angle parameter.…”

The influence of strain state on the kinetics of martensitic phase transformation in stainless steel 304 is investigated. The methodology involves stretching various specimens with different widths over a hemispherical punch. The specimens are stretched to various depths by controlling the punch traveling in order to achieve different strain levels. The volume fraction of strain induced martensite is then measured using ferrite scope and plotted versus strain for different strain states. The results show that the martensitic transformation curve has the lowest value for plane strain condition among strain states used for determination of forming limit diagram. There are a close proximity between the two sets of the experimental data and those of the modified Olson-Cohen and Santacreu's models.
