observed between a shot type of S70H and S110H, and pressures of 30 psi and 75 psi. CRS maximums are normally observed within 40 𝜇𝜇m of the surface. Shot peening the M2Nit. had no observed effect on residual stress because of the white layer and case depth. In addition, more aggressive shot peening of the M2Nit. is needed to remove the white layer.

Place necessary stress raisers away from highly stressed shaft regions if possible. If unavoidable, use generous radii and good surface finishes. Consider local surfacestrengthening processes (shotpeening or coldrolling). Use inexpensive steels for deflectioncritical shafts because all steels have essentially the same modulus of elasticity.

Shot Peening. CurtissWright Surface Technologies is an industry leader in shot peening, a cold working process in which small spherical media called shot bombard the surface of a part. During the shot peening process, each piece of shot that strikes the material acts as a tiny peening hammer; this imparts a small indentation or dimple to...

Shot peening has been used successfully for many years. Although skill trades realized the benefits of this coldworking process long ago, modern shot peening has only had widespread use since the 1930''s. In 1945 a patent was issued to John Almen for a method to measure the intensity of shot peening. Mr.

It is the process of working a metal''s surface to improve its material properties by mechanical means such as hammer blows or by blasting with shot (shot peening). Peening is normally a cold work process (laser peening being a notable exception). It tends to expand the surface of the cold metal,...
processes ( shot peening (SP), and laser shock peening (LSP)) are more established. Still, a detailed knowledge is not comprehensively reported. Also, all the works reported in literatures were carried out in a singlepass treatment. [4] TÖNSHOFF, et al.: Highpressure water peening a new mechanical surfacestrengthening process.
