  • Grain boundary decohesion by nanoclustering Ni and Cr

    The loss of ductility with temperature has been widely observed in tensile tests of single-phase face-centered cubic structured high-entropy alloys (HEAs). However the fundamental mechanism for such a ductility loss remains unknown. Here we show that ductility loss in the CrMnFeCoNi HEA upon deformation at intermediate temperatures is correlated with cracking at grain boundaries (GBs).

    Metallography and Microstructure of Aluminum and Alloys

     · Compared to many other metals and alloys and many other materials such as carbides ceramics and sintered carbides aluminum and its alloys are low in strength and hardness. Aluminum is a soft silvery metal with a face-centered cubic crystal structure a hallmark of ductile metals. Its softness makes it somewhat difficult to prepare but the alloy is not sensitive to problems that plague

  • Polishing vs. Buffing What s the Difference Products

     · Polishing generates a brushed or lined finish where buffing removes the lines and creates a bright luster finish. The process of buffing generally requires surface refinement polishing prior to buffing. Polishing by abrasive belts or discs is required to level surfaces remove scratches pits scale and polish the surface enough so the cut
