  Abstract NOTE: The first page of text has been automatically extracted and included below in lieu of an abstract Session 1664 A Novel Approach to Hardness Testing F. Xavier Spiegel, Harvey A. West, 11 Loyola College/Materials Analytical Services Key Words: Hardness, rebound, scleroscope, coefficient of restitution Prerequisite Knowledge: Knowledge of physical testing of metallic materials Objective: To demonstrate a simple rebound hardness measuring device and explore its applications and limitations. Equipment: 1. Rebound hardness tester as outlined in Reference 1. 2. Several metallic samples of various compositions and harnesses. Introduction: This paper gives a description of the application of a simple rebound time measuring device and relates the deterrniniition of relative hardness of a variety of common engineering metals. A relation between rebound time and hardness will be sought; hardness is the ability of a material to resist permanent deformation and is typically quantified by relating the geometry of an indentor and normal force applied to the depth of penetration. The effect of specimen geometry and surface condition will also be discussed in order to acquaint the student with the problems associated with rebound hardness testing. Procedure: A complete description of the construction of the apparatus is contained in Reference 1. This device, constructed for under $100, is designed to repeatedly drop a 5.59 mm (0.220 in.) diameter ball from a fixed height of 9.0 cm (3.54 in.) onto a metal specimen clamped to a rigid base. A microphone coupled through an operational amplifier precisely relays the initial contact and subsequent rebound contact. A timing circuit is used to measure the interval between these events and calculates the rebound time, relatable to the coefficient of restitution of materials, a dimensionless quantity which is the negative of the relative velocity of two objects after a collision, divided by their relative velocity before the collision. $iiii’ ) 1996 ASEE Annual Conference Proceedings ‘.%,~y~’;:

• Additive Manufacture of RF Sources

  2018-06-24 · 3 citations

  article

  Calabazas Creek Research, Inc. (CCR), in collaboration with the Center for Additive Manufacturing and Logistics (CAMAL) at N.C. State University, is investigating additive manufacture (AM), commonly referred to as 3-D printing, of RF sources. The goal is to dramatically reduce the cost of klystrons, traveling wave tubes, cross field amplifiers, and other vacuum electron devices. Typical high power klystrons are built from approximately 300 individually machined and fabricated parts, in addition to tens of machined subassemblies. The goal of this program is to reduce the number of parts by 80% and the number of subassemblies by 75%, with a corresponding decrease in cost.

• Characterization of Ni–Ti Alloy Powders for Use in Additive Manufacturing

  Russian Journal of Non-Ferrous Metals · 2018-07-01 · 27 citations

  articleSenior author

  Additive manufacturing (AM) offers a fully integrated fabrication solution within many engineering applications. Particularly, it provides attractive processing alternatives for nickel-titanium (Ni–Ti) alloys to overcome traditional manufacturing challenges through layer by layer approach. Among powder-based additive manufacturing processes, the laser beam melting (LBM) and the electron beam melting (EBM) are two promising manufacturing methods for Ni–Ti shape memory alloys. In these methods, the physical characteristics of the powder used as raw material in the process have a significant effect on the powder transformation, deposition, and powder-beam interaction. Thus, the final manufactured material properties are highly affected by the properties of the powder particles. In this study, the Ni−Ti powder characteristics are investigated in terms of particle size, density, distribution and chemical properties using EDS, OM, and SEM analyses in order to determine their compatibility in the EBM process. The solidification microstructure, and after built microstructure are also examined for the gas atomized Ni–Ti powders.

• Pre-clinical evaluation of the mechanical properties of a low-stiffness cement-injectable hip stem

  Journal of Medical Engineering & Technology · 2017-11-07 · 8 citations

  article

  In total hip arthroplasty (THA), the femoral stem can be fixed with or without bone cement. Cementless stem fixation is recommended for young and active patients as it eliminates the risk of loss of fixation at the bone-cement and cement-implant interfaces. Cementless fixation, however, suffers from a relatively high early revision rate. In the current research, a novel low-stiffness hip stem was designed, fabricated and tested. The stem design provided the option to inject biodegradable bone cement that could enhance initial stem stability. The stem was made of Ti6Al4V alloy. The proximal portion of the stem was porous, with cubic cells. The stem was fabricated using electron beam melting (EBM) technology and tested in compression and bending. Finite-element analysis was used to evaluate stem performance under a dynamic load representing a stair descending cycle and compare it to the performance of a solid stem with similar geometry. The von Mises stresses and maximum principal strains generated within the bone increased after porous stem insertion compared to solid stem insertion. The low-modulus stem tested in this study has acceptable mechanical properties and generates strain patterns in bone that appear compatible with clinical use.
