Mechanical properties of machined components are controlled by inducing phase transformations in the outer layer of the materials. Induction hardening is one such manufacturing process where the surface hardness is enhanced while the core is retained with the original structure and characteristics. In this study, a mathematical model had been developed to predict the hardness and the volume fra...

• The DL-EPR was deployed to investigate the DOS in materials molten salt systems. tendency for IGC increased after aging at CSP system temperatures. studied synergic effect of and temperature on tendency. In this study, sensitivity four corrosion resistant candidate alloys; austenitic stainless steels (AISI 321 AISI 347) Ni-based alloys (IN 625 825) degrade by intergranular when used with salt...

In the 21 st century, numerical analysis is a proven tool for research and development of manufacturing processes. Mathematical modelling provides information about behaviour various materials during forming processes, instance. The real-world process therefore represented by an abstract mathematical model, on which calculations are performed. Three-roll skew rolling can be used grades steel. T...

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 work, the corrosion resistance of AISI 321 stainless steel is increased through. two-stage implantation oxygen ions and both aluminum boron together. During ion implantation, a modified layer with thickness about 200 nm formed, which affects properties material. The increase in confirmed by prolonged acid tests at pH 3.5 accelerated electrochemical using potentiostat. rate implanted sam...
