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, ...

As an advanced manufacturing technology which has been developed rapidly in recent years, high speed machining is widely applied in many industries. The chip formation during high speed machining is a complicated material deformation and removing process. In research area of high speed machining, the prediction of chip morphology is a hot and difficult topic. A finite element method based on th...

By a improved front light-source framing photography technique and a simple fragments soft recovered method, the expansion and fracture behaviour of the AISI 1045 steel cylinders loaded by three different brisance explosives have been studied . Cylinders were heat treated-normalized and quenched and tempered. Experimental results show that the more intensive of the loading ,the stronger capabil...

Previous studies have demonstrated that the wear-corrosion synergism can be markedly affected by the loading speed. In this study, effects of the loading speed or strain rate on corrosion and corrosive wear of annealed, impact-fractured and slow bending-fractured surface layers of AISI 1045 steel in a 3.5% NaCl solution were investigated using electrochemical, scanning Kelvin probing and electr...

In this paper, a methodology for work material constitutive model based calculations of forces, stress and temperature distributions in orthogonal machining are introduced. Oblique moving band heat source theory is utilized and combined with modified Oxley’s parallel shear zone theory. Non-uniform heat intensity at the tool-chip interface is obtained from the predicted stress distributions util...

In this Data in Brief paper, a central composite experimental design was planned to collect the surface roughness of an end milling operation of AISI 1045 steel. The surface roughness values are supposed to suffer some kind of variation due to the action of several factors. The main objective here was to present a multivariate experimental design and data collection including control factors, n...

In this investigation of AISI 1045 steel are tested in two stages. the first stage samples, induction boriding and hardening heat treatment typically 800 °C, 900 1000 1100 1200 °C applied over course seconds. Internal strains maybe mitigated using a 30 min tempering at temperature ranges 300 500 °Cand 700 °C. After that samples subjected to hardening, microhardness tensile strength according AS...

Article history: Received 12 September 2010 Accepted 27 September 2010 In this paper, the residual stress in quenched AISI 1045 steel was measured by a recently developed nanoindentation technique. Depth control mode was adopted to measure the residual stress. It was found that residual compressive stress was generated in the quenched steel. The material around nanoindents exhibits significant ...
