網頁2008年1月1日 · Chapter 3. Properties of solids at low temperature 57 From room temperature down to about 50 K, eq. (3.3) gives quite good value of cph T for most solids. Deviations from eq. (3.4) for T< D/10 depend on the material as shown in Fig. 3.1. This experimental study reveals that the Strenx 960 Plus steel retains its ductility at temperatures as low as − 40 C. Brittle failure could not be observed even with combined high strain rate, high stress triaxiality and low temperature. 查看更多內容 The material used in the current study is the hot-rolled, quenched and tempered strip steel Strenx 960 Plus which was produced and provided by Swedish Steel AB (SSAB). It is a high-strength martensitic steel … 查看更多內容 Charpy V-notch tests were carried out according to the ISO 148-1:2016 standard using an inverse setup (see Fig. 2) [16].
