Cyclic deformation and fatigue behaviour (B03)

B3研究了表现出增强界面结合的复合材料以及新开发的高氮钢的疲劳性能。除了调查处理的平均应力，平均应变和单调预变形的影响，分别，进一步的研究活动检查轴向扭转载荷下的循环行为。在循环裂纹扩展随机载荷和由此产生的材料行为和相变方面将进行检查。此外，B3研究了TRIP基质复合材料作为铝熔化炉底板的材料特性。所有的测试都伴随着微观结构的调查。

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.
