Effect of Tempering and Baking on the Charpy Impact Energy of Hydrogen-Charged 4340 Steel Journal of Materials Engineering and Performance

2014-10-01

Tempered AISI 4340 steel was hydrogen charged and tested for impact energy. It was found that samples tempered above 468 °C (875 °F) and subjected to hydrogen charging exhibited lower impact energy values when compared to uncharged samples. No significant difference between charged and uncharged samples tempered below 468 °C (875 °F) was observed.

Characterization of the Effects of Active Filler-Metal Alloys in Joining Ceramic-to-Ceramic and Ceramic-to-Metal Materials Defect and Diffusion Forum

2014-06-01

This study investigated actively brazing Alumina-to-Alumina with Ag-Cu-Ti as the filler metal system and Alumina-to-Copper with Cu-Ti-Co as the filler-metal system. The research was conducted on four samples, two of which were alumina brazed to alumina (Samples 1 & 2), and the other two were alumina brazed to copper (Samples 3 & 4).

Double shroud delivery of silica precursor for reducing hexavalent chromium in welding fume Journal of Occupational and Environmental Hygiene

2012-12-01

The welding process yields a high concentration of nanoparticles loaded with hexavalent chromium (Cr(6+)), a known human carcinogen. Previous studies have demonstrated that using tetramethylsilane (TMS) as a shielding gas additive can significantly reduce the Cr(6+) concentration in welding fume particles. In this study, a novel insulated double shroud torch (IDST) was developed to further improve the reduction of airborne Cr(6+) concentration by separating the flows of the primary shielding gas and the TMS carrier gas.

Innovative Manufacturing Process for Defect Free, Affordable, High Pressure, Thin Walled, Hydraulic Tubing Journal of Materials Engineering and Performance

2011-10-01

Various thermo-mechanical processes were performed on a standard and a low oxygen content Ti-6Al-4V alloy. Testing was performed to determine whether it was possible to achieve a combination of tensile properties comparable to those of Ti-3Al-2.5V by means of cold working and annealing Ti-6Al-4V from a thickness of 0.671cm (0.264 in.) to that between 0.081 and 0.094cm (0.032-0.037 in.), which had never been carried out before.

On the Distortion and Warpage of 7249 Aluminum Alloy After Quenching and Machining Journal of Materials Engineering and Performance

2011-10-01

The objective of this study is to determine the effect of solution treatment temperature, quenching media, and various machining sequences on the warpage behavior of aluminum 7249 alloy aged to T6 and T7′ tempers. Large extrusions of 7249 aluminum alloy with fins were cut into 108 “T” sections. The samples were solution-treated, aged, and machined.

Effect of Stretch Orientation and Rolling Orientation on the Mechanical Properties of 2195 Al-Cu-Li Alloy Journal of Materials Engineering and Performance

2011-10-01

Sheets of 2195 aluminum-lithium alloy were solution-treated at 507°C for 30min. One set was stretched to 3-5% in the 0°, 45°, and 90° angle with respect to the original rolling direction. Two other sets were rolled 6% reduction in thickness and 24% reduction in thickness in the 0°, 45°, and 90° angle with respect to the original rolling direction.
