Laser peening (LP), or laser shock peening (LSP), is a surface engineering process used to impart beneficial residual stresses in materials. The deep, high-magnitude compressive residual stresses induced by laser peening increase the resistance of materials to surface-related failures, such as fatigue, fretting fatigue, and stress corrosion cracking.
Dr. Allan Clauer, an original patent holder of the laser peening process, [3] and a Battelle inventor of the laser shock peening process, joined LSPT as Vice-President later in 1995. In 1996 to 1999, LSPT assembled and delivered three high power ND: Glass laser peening systems to General Electric Aviation in Cincinnati, Ohio.
Metal Improvement Company LLC, part of Curtiss-Wright, is a company specializing in metal surface treatments.. MIC provides multiple technical services for the metal treatment industry, including thermal spray, solid film lubricant and parylene coatings, and materials testing services; but is best known for its legacy shot peening technology, which can enhance the performance of metal ...
Pittsburgh used the two-rate system from 1913 to 2001 [21] when a countywide property reassessment led to a drastic increase in assessed land values during 2001 after years of underassessment, and the system was abandoned in favor of the traditional single-rate property tax. The tax on land in Pittsburgh was about 5.77 times the tax on ...
Texas officials try to intercept sale of surplus border wall materials Patrick noted that Texas became aware of the materials slated for auction on Dec. 12, the same day the Daily Wire reported ...
In metallurgy, peening is the process of working a metal's surface to improve its material properties, usually by mechanical means, such as hammer blows, by blasting with shot (shot peening), focusing light (laser peening), or in recent years, with water column impacts (water jet peening) and cavitation jets (cavitation peening).

Texas has seen a population spike in recent years. In 2022, the population grew by 470,708. And in 2023, the Lone Star State gained more people than any other state that year.
The cold work temperature produced from this process is typically minimal; similar to the cold work produced by laser peening, but a great deal less than shot peening, gravity peening or, deep rolling. Cold work is particularly important because the higher the cold work temperatures at the surface of a component, the more vulnerable to elevated ...
