(2015-05-01)Additive Manufacturing (AM) process parameters were studied for production of the high temperature alloy Inconel 718 using Electron Beam Melting (EBM) to better understand the relationship between processing, microstructure, ...
-
(2018-05-04)We use molecular dynamics simulations of cyclic deformation to investigate the viscoelastic response of two-component, defect-free, face-centered cubic equiatomic solid solutions (ESSs). Rather than simulate a specific ...
-
(2018-02-20)Theory predicts that carbon nanofibers (CNFs), processed via carbonizing polymeric nanofibers, as down-sized version of carbon fibers (CFs) should be significantly stronger than CFs, due to size-dependent defects in CFs ...

Effects of Water Content and Alumino-Silicate Sources on the Structure and Properties of Geopolymers (2012-10-19)Geopolymers (GPs) are a special class of inorganic polymers with unique properties. Their 3-D amorphous structure and properties are often attributed to SiO2/Al2O3 molar ratios. However; contradictory results reported in ...
-
(2011-10-21)The present study employs a standardized progressive load scratch test (ASTM D7027/ISO 19252) to investigate the fundamental physical and mechanistic origins of scratch deformation in styrene-acrylonitrile (SAN) random ...
-
(2019-03-07)Precipitation hardenable aluminum alloys are well-known for their high strengthto-weight ratio, good thermal stability, electrical conductivity, and low cost. Al-Sc alloys micro-alloyed with rare earth and transition metal ...
-
(2021-04-26)Clinical treatments for intervertebral disc (IVD) degeneration aim to relieve pain and stabilize the spine. However, recovery is limited by a lack of adequate replication of joint mechanics, donor site morbidity, and a low ...

Improvement in the Mechanical Properties of B-Staged Carbon Nanotube/Epoxy Based Thin Film Systems (2011-01-11)Polymeric systems have been the subject of tremendous interest to the aerospace industry due to their high strength per weight ratio but have not seen the use projected due to their poor compression after impact strength, ...
-
(2015-07-23)Total Knee Arthroplasty (TKA) is a common treatment for patients with severe knee pain due to osteoarthritis, a condition characterized by the loss of articular cartilage or injury. Most patients that opt to proceed with ...

Mechanical Behavior and Irradiation Response in Nanostructured Metals with Low Stacking Fault Energy (2017-08-03)High-energy particles introduce significant damage to nuclear structural materials and eventually lead to the failure of the materials. Austenitic stainless steels, as a widely used structural material in current nuclear ...
-
(2013-04-26)Austenitic stainless steels are commonly used in nuclear reactors and have been considered as potential structural materials in fusion reactors due to their excellent corrosion resistance, good creep and fatigue resistance ...
-
(2012-10-19)Bulk nanocrystalline 304L and 316L austenitic stainless steels (SS) were produced by equal channel angular pressing(ECAP) at elevated temperature. The average grain size achieved in 316L and 304 L SS is ~ 100 nm, and grain ...
-
(2011-10-21)Geopolymers (GPs) are a new class of inorganic polymers that have been considered as good candidate materials for many applications, including fire resistant and refractory panels, adhesives, and coatings, waste encapsulation ...
-
(Texas A&M University, 2004-09-30)This study looks at improving reduced platen compression (RPC) specimen preparation procedures by developing a better method for locating the ideal RPC specimen on each bone. These improvements are aimed at decreasing the ...
-
(Texas A&M University, 2007-09-17)Rats that undergo hindlimb unloading (HU) as a simulation for space flight experience bone changes similar to astronauts in microgravity. The purpose of this research was to assess whether an exercise countermeasure would ...
-
(2014-08-14)Layer-by-Layer (LbL) assembly technique is a powerful approach to blend two or more materials to form new materials of thin films on any type of substrate, and the LbL film is called polyelectrolyte multilayers (PEMs). The ...
-
(2012-10-19)Carbon nanotubes (CNTs) and carbon nanofirbers (CNFs) have excellent properties (mechanical, electrical, magnetic, etc.), which can make them effective nanoreinforcements for improving the properties of materials. The ...
-
(2013-12-11)The rheology and linear viscoelasticity of several model nanoparticle suspensions in epoxy have been systematically investigated. Three detailed studies were carried using α-zirconium phosphate (ZrP) nanoplatelets as model ...
-
(2021-04-09)The susceptibility of polymers to surface damage like scratch significantly limits their use in applications where both surface structural integrity and aesthetics are important. The present study employs a standardized ...
