Cast iron presents graphite particles of different shapes that directly affect its thermo-mechanical properties [1]. Fracture toughness and ductility depend strongly on the shape of the graphite particles. Particles with nodular shapes improve these properties while more elongated particles or with irregular contours are detrimental due to stress concentration points [2]. Thus, cast iron is cla...

Blue rubber bleb nevus syndrome is a sporadic disease with widely distributed dark blue papules and nodules and soft skin-colored compressible protuberances (rubber blebs) as well as large vascular malformations. Gasterointestinal lesions are documented by upper endoscopy and colonoscopy; hemorrhages from these lesions create irondeficinecy anemia. Other sites of visceral involvement are less c...

In this study, we investigated the cutting performance and wear mechanisms of Ti(C,N)-based tools containing varying weight percentages (0%, 5%, 10%, 15%) high-entropy carbide (HEC) (V0.2Nb0.2 Mo0.2Ta0.2W0.2)C phase, when used for turning nodular cast iron. According to test results, cermet 0 wt%, 5 10 15 wt% HEC phases demonstrated effective lives 402, 720, 632, 465 s, respectively. The tool w...

In this study, a cladding layer and nitriding were prepared on nodular cast iron, to provide guidance for remanufacturing of iron. Their microstructure composition the tribological properties under dry starved lubrication conditions studied. Meanwhile, contact stresses at different friction stages simulated through finite element method. The micro-hardness 694 HV0.5 724.5 HV0.5, which 4 times 4...
