    Twelve additively manufactured Inconel 718 metal samples, a high-strength nickel-based alloy, 
    were subjected to mechanical loading tests and fracture surface examination. Six samples are 
    subjected to torsional loading to failure, while six samples are subjected to elastic tensile loading. 
    The specimens tested are split into two categories: heat-treated and un-heat-treated. The material 
    is manufactured using Laser Powder Bed Fusion (L-PBF), an additive manufacturing process in 
    which a high-energy laser selectively melts successive layers of metal powder to build a solid 
    component. Due to the newness of this technology, limited information is available on how the 
    L-PBF process affects material properties.
    The purpose of these tests is to determine application-based mechanical properties of additively 
    manufactured Inconel 718 at room temperature under torsional and tensile loading. Properties of 
    interest include Ultimate Torsional Shear Strength, Torsional Yield Strength, Shear Modulus, 
    Modulus of Elasticity, Proportional Limit, and Poisson’s Ratio. The mechanical properties 
    determined for both heat-treated and un-heat-treated specimens show noticeable variation when 
    compared to published experimental values, indicating potential effects from additive 
    manufacturing parameters and post-processing conditions.
    Overall, the tests demonstrate the ability of this high-strength, ductile material to withstand 
    considerable deformation under torsional loading. Fracture surface examination shows that both 
    sample types predominantly fail along the plane of maximum shear, producing flat fracture 
    surfaces consistent with ductile material behavior and predictions from Mohr’s circle for pure 
    torsion. This study contributes experimental insight into the mechanical response of L-PBF 
    Inconel 718 in torsion and tension.

    Jonathan Serbest - Mechanical Engineering junior at Florida State University, Honors student, and current Vice President of RAM (Rocketry and Mechatronics) as well as SAME Chapter President in Panama City, FL. I’m gaining hands-on experience through an internship in the MEP field and plan to pursue a master’s in Systems Engineering to deepen my expertise. Passionate about engineering, leadership, and Olympic weightlifting. I'm seeking opportunities that value innovation, systems thinking, and a proactive, growth-oriented mindset. 

      

    Case Dyer - I am a highly motivated, hardworking, and principled student with experience in SolidWorks, 2-D AutoCAD, and basic computer skills pursuing a summer internship in the field of Mechanical Engineering. 

    What inspired me to enter into the field of Mechanical Engineering was when the engine in my 2003 VW Jetta 1.9L TDI failed. I decided to take it apart and find what had failed in my engine and how I could fix it. After much work, I ended up having to replace the entire cylinder head of my engine, but eventually I put it all back together and am still running this four-cylinder diesel saving machine 50,000 miles later with now 357,000 miles.
