B3 investigates the fatigue properties of the composites exhibiting enhanced interfacial bonding as well as of the newly developed high-nitrogen steels. Besides investigations dealing with the influence of mean stress, mean strain and monotonic pre-deformation, respectively, further research activities examine the cyclic behaviour under axial-torsional load. In terms of cyclic crack growth random loads and the resulting material behaviour and phase transformations will be examined. Furthermore, B3 investigates the material properties of a TRIP-Matrix-Composite regarding its application as a bottom plate in an aluminium-melting furnace. All tests are accompanied by investigations of the microstructure.

B3 研究了界面结合增强的复合材料以及新开发的高氮钢的疲劳性能。除了分别研究平均应力、平均应变和单调预变形的影响外，进一步的研究活动还研究了轴向扭转载荷下的循环行为。在循环裂纹扩展方面，将检查随机载荷以及由此产生的材料行为和相变。此外，B3 研究了 TRIP 基体复合材料作为铝熔炉底板应用的材料特性。所有测试都伴随着微观结构的研究。
