Bulk-scale evaluation
Research materials: Additively manufactured (AM) Inconel 718 and 316L SS, Shape memory alloys (SMAs), etc.
Mass production and standardization were the main emphasis in the second industrial revolution from the late 1800s to early 1900s. A great advancement in the manufacturing sector has boosted the production lines with increasing demand for new technologies that improves the comfort of our daily lives. As years pass by, neither the requirement of components with complex structural design could be satisfied by the technological advancement, nor the mass-produced items were able to satisfy the value appraisal of scarcity. Prototyping has faced challenges in demands of custom-designed items based on individual preferences, and reduction in efficiency to accustom the same design across industries.
The introduction of additive manufacturing (AM) methods presents the solution towards rapid prototyping by its capability to "print" components of desirable materials with specific designs, at a great reduction of cost and time required than that of conventional fabrication methods. In particular, a great amount of efforts is underway to utilize this technique for manufacturing large components with complexity in its design structure.
In aligning our focus towards the spurt of the additive manufacturing market, we believe that a detail investigation is required to carefully examine and assess the behaviors of the additively manufactured materials in bulk-scale, namely Inconel 718 and 316L SS, and compare its responses to that of the conventional counterparts. With a universal tensile tester and a custom-built furnace, a series of uniaxial tensile tests and fatigue and creep tests is conducted at various temperatures.
