Fe-based bulk metallic glasses: Brittle or ductile?

Abstract: Fe-based bulk metallic glasses (BMGs) typically exhibit ultrahigh strength but a poor ductility. Here, an Fe62Ni18P13C7 BMG with a super large plasticity of above 50% is reported. Such a discovery is guided by understanding a composition-strength-ductility map, in which most of Fe-based BMGs are classified into three types: FeC(B)-based, FeB-based, and FeP(C)-based. We demonstrate that the mechanical properties of the different types of BMGs are linked with their different physical properties. Among the three types of BMGs, the FeP(C)-based BMGs often possess a lower glass transition temperature, a lower shear modulus, and a higher Poisson's ratio, resulting in a lower shear flow barrier and a higher plasticity. Our findings provide a guideline in understanding the mechanical behavior of Fe-based BMGs.

How Is Emotional Intelligence Linked to Life Satisfaction? The Mediating Role of Social Support, Positive Affect and Negative Affect

Abstract: This study investigated the role of social support and affective experience (i.e., positive affect and negative affect) in the relationship between emotional intelligence and life satisfaction. Participants included 748 Chinese adults with an age range of 16–60 years who completed the Wong Law Emotional Intelligence Scale, the multi-dimensional scale of perceived social support, the Positive Affect and Negative Affect Scale, and the Satisfaction with Life Scale. Structural equation modeling demonstrated that social support, positive affect and negative affect independently mediated the effect of trait emotional intelligence on life satisfaction, consistent with the social network and affective meditation models. More importantly, the identified serial mediation model indicated that emotional intelligence could influence life satisfaction through the chain mediating effect of “social support–positive affect” and “social support–negative affect”. These findings contribute to a deeper understanding of the links between these factors and suggest that high emotional intelligence may promote well-being from the social support and affective perspectives.
