| dc.description | In nodular cast iron molybdenum is alloyed in the range of 0.5 wt.-% to 1.5 wt.-% to increase the mechanical properties for high temperature application, especially for thick-walled castings like housings of gas or steam turbines. The behaviour of Mo-precipitations in the as cast state as well as under long exposure to heat was the object of this investigation. In the as-cast state Mo forms metastable carbidic grain-boundary precipitations with iron, silicon and carbon. These transform into stable MoC precipitations during sustained temperature influence. Furthermore, there are finely dispersed Mo-containing precipitations found in the matrix. These increase the high temperature strength of Mo-alloyed cast iron due to the Orowan mechanism and the occurrence of additional grain boundaries. However, it has been shown that these Mo-containing precipitations underlie Ostwald ripening under continuous heat exposure and a precipitation free area occurs along the ferritic grain boundary. | |
