In this study, some mechanical properties of borided and unborided four steels were investigated. Boronizing of steels was performed by powder pack method at 1210 K for 4 h. The hardness of borides, boride layer thickness and room temperature tensile properties were measured and it was observed that hardness and tensile properties strongly depend on chemical composition of steels. In addition, ...

In this paper, we have characterized the microstructural evolution and plastic flow fracture behaviours of AISI 304L 316LN stainless steel grades at liquid nitrogen temperature (77K) helium (4K). Uninterrupted tensile experiments, where sample is continuously deformed under quasi-static loading conditions until fracture, been carried out with a Single-Section Sample to obtain stress–strain char...

Abstract Residual stresses are one of the major issues in welded parts, since they could be detrimental to integrity components and structure. Their determination is rather complex an arduous task, both when it based on experimental methods numerical simulations. The proposed work presents a theoretical approach prediction longitudinal residual stress distribution, parameterized multi-source mo...

In this study, the hardness and wear behaviour of carburized and boronized AISI 8620 steels have been studied. The boronizing treatment increased the hardness of AISI 8620 steels from 395 HV0.1 to a maximal 1610 HV0.1 compared to the carburized steels and also significantly improved its wear behaviour. From obtained results, it can be concluded that boronizing is very effective surface hardenin...

Background: The austenitic stainless steel 304L is widely used as a structural material for which the finished surface has significant effect on the service performance. A study of the grinding process with regard to the quality of the ground surfaces is therefore interesting from the point of view of both industrial application and scientific research. Method: This work investigates the influe...
