INFLUENCE OF COOLING RATE ON THE OCORRENCE OF RETAINED AUSTENITE IN A STEEL FOR WELDING ELECTRODES [PDF]
Tecnologia em Metalurgia, Materiais e Mineração, 2015 The effect of cooling rate on the occurrence of retained austenite in a low carbon Si-Mn steel, used for welding electrodes, is measured here by combining the sectioning of Jominy test samples with the measurement of retained austenite by X-ray ...

Advanced Science, EarlyView.Perovskite‐type oxide lanthanoid‐substituted BiCoO3 exhibits a reversible negative thermal expansion (NTE) originated from the coordination change from the CoO5 pyramid to the CoO6 octahedron due to melting of the dxy orbital ordering in the d6 electron configuration, and the 6.1% volume shrinkage in Bi0.82Nd0.18CoO3 is the largest ever observed in the

THE POSSIBILITIES OF THE RETAINED AUSTENITE REDUCTION ON TOOL STEELS
European Journal of Materials Science and Engineering, 2021 The retained austenite induces a great deal of internal stress in the steel, often manifesting itself as cracks. Retained austenite also have a negative effect on dimensional stability of the steel components. In tool steels retained austenite is considered to be highly detrimental and is the cause of many application failures. Tool steels must be able

Advanced Intelligent Systems, EarlyView.Inspired by the Mexican jumping bean, this study presents a centimeter‐scale, electronics‐free robot that merges principles from both the animal and plant kingdoms. A thermo‐responsive actuator mimicking larval motion, enclosed within a uniquely shaped plant‐seed‐inspired shell, generates jumping, rolling, flipping, sliding, and climbing through ...
