“…In Figure 9b, the formation of a high dense dislocation wall (HDDW) acting as a barrier against dislocation motion is also observed. However, the subsequently formed deformation twin plates penetrate the HDDW as reported previously [48,60], indicating that the stress concentration that occurs by interactions between a HDDW and deformation twinning is easily accommodated. From the TEM images, the dislocation density around the highly dense dislocation area and the average thickness of primary twins were determined as 3 × 10 14 m -2 and 35 nm, respectively.…”

The effects of tensile strain rate on the hydrogen-induced mechanical and microstructural features of a twinning-induced plasticity (TWIP) steel were investigated using a Fe-23Mn-0.5C steel with a saturated amount of hydrogen. To obtain a homogeneous hydrogen distribution, high-pressure hydrogen gas pre-charging was performed at 423 K. Similar to previous studies on hydrogen embrittlement, the deterioration in the tensile

“…Furthermore, the macrohardness (HV10) of the base materials was 202 AE 4 [0Z], 199 AE 3 [5Z], and 189 AE 3 [10Z]. Similar composite materials prepared via hot-pressing [18] showed a more pronounced correlation between the macrohardness (HV10) and the material's composition. Here, by adding magnesia partially stabilized zirconia particles, the macrohardness increased by 37% (5 vol% Mg-PSZ) and 45% (10 vol% Mg-PSZ) compared to the pure steel specimens.…”

Metal-matrix composites composed of an austenitic stainless steel and magnesia partially stabilized zirconia were prepared via a powder metallurgical processing route with the ceramics-derived extrusion at room temperature. Various combinations of the base materials with zirconia volume fractions of 0, 5, and 10% were joined by applying an aqueous paste which forms the joint during thermal processing. The materials were tested under tensile loading at room temperature. The addition of zirconia particles led to a considerable decrease of the plasticity and ultimate tensile strength of the basic compositions. However, the strength of joint specimens was not limited by the bonding strength of the joining zone. Among all material combinations tested, failure occurred in the joining partner with the higher zirconia volume fraction and not at the joint interface. Thus, the strength of sinter-joined materials based on MMC with 0-10 vol% was limited by the strength of the base materials. The advance of the present sinter-joining method is the single thermal operation of the composite materials. The formation of a homogeneous bonding zone and the absence of a heataffected zone lead to negligible interference with the microstructure and the mechanical properties of the base materials.

“…Application of pure ZrO 2 component is hindered because of catastrophic fracture due to volume expansion (approximately 4%). However, stabilizers, such as Y 2 O 3 , CaO or MgO can be employed (Glage, Weigelt, Räthel & Biermann, 2014). Yttria on the other hand increases the wettability with steel.…”
