Abstract
Titanium alloys have gained attention in the aerospace and defense sectors due to their unique strength and light weight. A unique severe plastic deformation (SPD) method of large strain machining (LSM) was used to fabricate chips of Ti6Al4V titanium alloy in the present investigation. Since the technique employed previously doesn’t match current expectations and demand of the industry, this technique solves the problem of the former technique to manufacture bulk nanostructured materials. In the present experimental work, investigation and property analysis is carried out. Response surface methodology (RSM) has been used to develop the input output relations. Feed, rake angle, and speed have been considered as input parameters, and shear strain, hardness, and surface roughness have been considered output parameters. Based on experiments carried out, Box–Behnken design technique has been used to develop nonlinear models. Experiments are carried out on an HMTLT 21 lathe with the help of a special design tool post. The mechanical properties of the strips produced were measured by a microhardness tester. Also, the surface roughness and surface morphology of strips were studied using a surface roughness tester and scanning electron microscope (SEM).While measuring the hardness of strips produced, it was revealed that the hardness of strips was greater than that of the alloy. Similarly, properties of the surface were found to be improved.
