This paper reports an investigation of the influence carbonitriding conditions for 20MnCr5 low alloy steel. Three gaseous were investigated based on different carbon and nitrogen potentials to attain varying levels between 0.62 0.93% mass, whereas 0.19 0.26% mass at surface. Analysis retained austenite residual stress distributions was conducted using X-ray diffraction technique. The effective ...

A new process combining 4% prestrain, intercritical annealing, quenching, and partitioning (prestrain–IA–Q&P) is used to investigate the effect of tensile number on microstructure mechanical properties medium‐manganese steels. microstructural model built based specimens’ properties. The amount tiny brilliant white carbide particles precipitated in seems grow with stretches. test steel's str...

the development of nano/ultrafine bainitic structure in aisi 52100 steel was the goal of this study. for this purpose,the aisi 52100 the specimens were austenitized at 1050 °c for 60 min followed by low-temperature austemperingtreatment at different temperatures and times. the austempered samples were characterized using field emissionscanning electron microscopy (fesem), x-ray diffraction (xrd...
