Abstract Scope |
The processing of functionally graded materials using laser-based additive manufacturing technologies has gained attention due to its applicability in the local tailoring of compositions within a component. However, the conventional mechanical testing methods have remained a bottleneck for probing the immense space developed by the material gradients because of their time-consuming and cumbersome nature. This paper proposes the Small Punch Test (SPT) as a high throughput mechanical testing method to produce reliable stress-strain curves and evaluate the constitutive behavior of the graded materials. The data obtained from micro-hardness and tensile correlated SPT tests are used to attain the structure-property characteristics for novel material compositions of graded stainless- steel and nickel superalloys. Solidification behavior and microstructures observed through electron microscopy and X-ray diffraction methods are validated against the CALPHAD based Scheil model simulations. The material characterization framework examined in this study proves an efficient path for developing and qualifying new materials. |
