Effect of Tungsten Addition on the Nucleation of Borides in Wide Gap Brazed Joint
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Wide gap brazing (WGB) is a cost effective and reliable means to repair gas turbine hot section components with defect sizes exceeding 0.3 mm. However, it has been shown that WGB joints of ...
Brazing and Wide Gap Repair of X-40 Using Ni-Base Alloys
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Co-base superalloys are commonly used for vanes and parts of the combustion chamber in gas turbine engines. The Co-base superalloys are primarily solid solution strengthened and have good ...
Investigation of Stress Assisted Grain Boundary Oxidation Cracking in MAR-M002 High Pressure Turbine Blades
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Modern superalloys have enabled high pressure turbine (HPT) blades in gas turbine engines (GTE) to operate at higher temperatures. Unfortunately, the complexity of these materials can make it ...
Fatigue Properties of Narrow and Wide Gap Braze Repaired Joints
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: With the increasing utilization of braze repair in the gas turbine industry, the properties of braze joints under simulated service conditions become vital in selecting braze repair over other ...
Tribological Behaviors of Titanium Nitride- and Chromium-Nitride-Based Physical Vapor Deposition Coating Systems
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This study investigates the effects of the deposition process and coating composition on microstructural and tribological properties of TiN- and CrN-based coating systems. Coatings were produced ...
Reliability-Based Truck Weight Regulation of Small- to Medium-Span Bridges
Publisher: American Society of Civil Engineers
Abstract: Truck weight regulations maintain controls on the actual truck-load characteristics and can further affect the serviceability of constructed infrastructures. To investigate the truck weight regulations of small- to medium-span ...
Synthesis and Properties of Sulfoaluminate Cement Modified with Nanoparticles at Low Temperature
