Thermomechanical processing of low carbon bainitic steels is used to obtain a microstructure with good strength and toughness by continuous cooling after forging without the need further heat treating, hence reducing manufacturing costs. However, hot parameters can significantly influence in forged material. A series treating experiments was carried out analyze effect austenitizing time temperature on grain growth Prior Austenite Grain Size (PAGS) continuously cooled microstructure. The...
Abstract The main aim of this work is to investigate the effects combinative Ce and Zr additions (0.3 wt% + 0.16 Zr; 0.3 0.27 0.36 Zr) on microstructure mechanical properties in cast Al–Si–Cu–Mg alloy. microstructures features were investigated by optical microscope, scanning electron microscope hardness measurements. microstructural analysis has shown that increase contents increases volume fraction intermetallics formed during solidification leading grain refinement changes silicon...
Abstract In the field of massive forged components mechanical engineering industry searches for processes with increasing energy and resource efficiency. The new generation bainitic steels are promising such application because high strength, toughness fatigue properties. order to achieve desired properties, development microstructure depending on parameters thermomechanical process cooling procedure must be well-known. present work diverse experimental techniques were applied investigation...
In this work, the microstructural evolution during dynamic transformation of austenite to bainite was directly observed by in-situ high energy synchrotron X-ray diffraction measurements warm uniaxial compression performed at P07 beamline PETRA III, DESY (Deutsches Elektronen-Synchrotron). Plastic deformation triggers phase transformation, which is continuously stimulated introduction dislocations into austenite. This scenario accelerates kinetics formation in comparison with conventional...
