Understanding the metallurgical joinability of pure Mg and Fe their interfacial microstructure lays foundation for deciphering complicated mechanism joining various magnesium alloys steels in applications. Pure were successfully joined to form a bond first time using friction stir assisted scribe technique. Through detailed characterization, we found that two immiscible metals are bonded by cri...

Pure type systems make use of domain-full-abstractions x : D : M. We present a variant of pure type systems, which we call domain-free pure type systems, with domain-free-abstractions x : M. Domain-free pure type systems have a number of advantages over both pure type systems and so-called type assignment systems (they also have some disadvantages) and have been used in theoretical developments...
