Prediction of machining induced residual stresses in turning of titanium and nickel based alloys with experiments and finite element simulations
Titanium and nickel alloys represent a significant metal portion of the aircraft structural and en components and the residual stresses induced by machining are very critical due to safety sustainability concerns. This paper presents experimental investigations and finite element simulat on turning of Ti–6Al–4V titanium alloy and IN100 nickel based alloy with uncoated and TiAlN co tools. Face t...
متن کاملMachinability evaluation of Titanium alloy in Laser Assisted Turning
The use of titanium and its alloys has increased in various industries recently, because of their superior properties of these alloys. Titanium alloys are generally classified as difficult to machine materials because of their thermo-mechanical properties such as high strength-to-weight ratio and low thermal conductivity. Laser Assisted Machining (LAM) improves the machinability of high strengt...

متن کاملWelding residual stresses in ferritic power plant steels
Many of the degradation mechanisms relevant to power plant components can be exacerbated by stresses that reside within the material. Good design or structural integrity assessments require therefore, an accounting of residual stresses, which often are introduced during welding. To do this it is necessary to characterise the stresses, but this may not be possible in thick components using non-d...
متن کاملSurface Residual Stresses in Dry Turning of 0.45% C Steel
Residual stresses in a surface layer determine many exploitation characteristics of machined surface. Depending on their kind and the type of applied loading, the influence of residual stresses can be negative or positive. Tensile residual stresses usually exert highly detrimental impact on several functional aspects such as strength, fatigue life, corrosion, wear resistance, etc., whereas comp...
