Abstract： Amidst intense competition, the precise recognition of innovative solutions aligned with the enterprise’s needs emerges as paramount for a company’s survival and growth. Decision-makers’ creativity recognition holds a central position in the literature on organizational creativity and innovation. However, existing studies often overlook the substantial impact of competition, leaving decision-makers’ cognitive biases and the underlying mechanisms unexplored. Consequently, research findings lack the explanatory power necessary for real-world phenomena. Within the corporate innovation process, decision-makers frequently engage in prolonged competition with closely matched opponents, transforming routine competition into enduring rivalry. Acknowledging this context, the current project adopts a relational competition perspective to investigate how the rivalry between decision-makers influences the accuracy of creativity recognition for both parties. Employing a mixed-method approach, encompassing laboratory experiments, field studies, and archival analysis across four studies, the project explores the nuanced effects of rivalry on decision-makers’ creativity recognition. Furthermore, the project seeks to unveil the mediating roles of cognitive processing depth and breadth paths while examining the boundary conditions. Leveraging the rivalry perspective, this project sheds new light on decision-makers’ cognitive biases in creativity recognition and the underlying mechanisms contributing to these biases. In terms of practical implications, this project can also assist decision-makers in comprehending and mitigating biases effectively.

Abstract： The Ni- based superalloys are widely used as microstructural components of modern turbine engines due to its good high temperature strength, good fatigue and creep property and excellent hot-corrosion resistance. In order to increase their high temperature strength, more and more refractory elements, such as W and Mo, are added into these alloys while Cr content gradually decreases. During long-term aging, these alloys generally experience various microstructural changes, including coarsening of g' phase coarsening, formation of a continuous grain boundary (GB) carbide network, precipitation topologically close-packed (TCP) phase, and degeneration of MC carbide. However, there is limited available data about the effect of (W+Mo)/Cr ratios on the microstructural evolution of Ni- based superalloys. In this work, the cast Ni- based superalloys with different (W+Mo)/Cr ratios (mass ratios) are fabricated by vacuum induction furnace. After standard heat treated (1110 ℃, 4.5 h, air cooling+ 750 ℃, 10.5 h, air cooling), they are thermally exposed at 850 ℃ for different times. The stress-rupture tests are operated under the condition of 800 ℃, 294 MPa. Effects of (W+Mo)/Cr ratios on the microstructure evolutions and mechanical properties are investigated by the combination of OM, SEM, TEM and stress-rupture tests. The experiment results show that the (W+Mo)/Cr ratio has no obvious influence on the standard heat treated microstructure, which is mainly composed of g matrix, g' phase, MC carbide and secondary carbides distributing at grain boundaries. During long-term thermal exposure, the microstructure evolutions occur by g' phase coarsening, TCP phases formation, MC degeneration and grain boundary coarsening. The g' phase coarsening behavior is not affected obviously by the (W+Mo)/Cr ratio. However, the amount of TCP phases decreases significantly with decreasing of (W+Mo)/Cr ratio and the type of TCP phases transforms from m phase to coexist of m and s phases when (W+Mo)/Cr ratio decreases from 0.55 to 0.37. There are no TCP phases observed in the sample with (W+Mo)/Cr ratio of 0.22. The thermal stability of MC carbide is reduced obviously and the grain boundaries coarsen more severely by the decrease of (W+Mo)/Cr ratio. The degradation of stress-rupture property is attributed to the coarsening of g'phase and grain boundaries and the formation of TCP phases. Combined with the effect of (W+Mo)/Cr ratio on the solid solution strengthening, microstructure evolution and stress-rupture property, it can be concluded that the optimumstress-rupture property can be obtained when the (W+Mo)/Cr ratio is about 0.37.
