Provided is a core wire for guide wire in which high rigidity can be attained even with a fine wire diameter so that pushability is improved while the core wire is prevented from fatigue deformation, and a method for manufacturing the core wire. This core wire 15 for guide wire is made of a Ti—Ni based alloy and has a wire diameter not larger than 0.5 mm and a Young's modulus not lower than 50 GPa. According to the manufacturing method, first, wire drawing is performed on a raw material M 0 so that the raw material M 0 is passed through a wire drawing dice 2 to be drawn to a certain length while the wire diameter of the core wire is reduced. Thus, a primary processed material M 1 is formed. After that, the primary processed material M 1 is hammered and drawn by swaging dices 5 and 5 so that a secondary processed material M 2 is formed. In this manner, the core wire 15 having a wire diameter not larger than 0.5 mm and a Young's modulus not lower than 50 GPa is manufactured.

The present invention is to provide a method for shot peening for producing a compressive residual stress that exceeds 60% of the yield strength at 0.2% offset without using stress shot peening. Shot media are peened onto a processed steel that has an amount of retained austenite in a range between 5 to 30%, and any change in the amount of retained austenite is controlled to be in a range of 2 to 30% before and after shot peening to produce the compressive residual stress in the processed steel. 2. The method for shot peening of claim 1 , wherein a change in the amount of retained austenite at the depth where the maximum compressive residual stress is generated is controlled to be in a range of 2 to 30% before and after shot peening to produce a compressive residual stress in the processed steel.3. The method for shot peening of or claim 1 , wherein the processed steel is a gas carburized steel. The present invention relates to a method for shot peening. Specifically, it relates to a method for shot-peening a steel.Conventionally, shot peening has been known to produce compressive residual stresses to improve the fatigue strength of parts made of a steel (see authored by the Society of Shot Peening Technology of Japan; Fatigue of Metals and Shot Peening; published by Gendai Kogaku-sha; 2004). Further, it has been known that increasing the maximum value of compressive residual stresses is very effective in improving the fatigue strength of the parts (see Masahiko Mitsubayashi, Takashi Miyata, and Hideo Aihara; Prediction of Improvement in Fatigue Strength by Shot Peening and Selection of Most Effective Peening Conditions; Transactions of JSME, Vol. 61, No. 586 (June, 1995) pp. 28-34).However, it is also known that the maximum value of compressive residual stresses produced by shot peening is approximately 60% of the yield strength at 0.2% offset (Hideki Okada, Akira Tange, and Kotoji Ando; Relationship among Specimen's Hardness, Residual Stress Distribution and Yield ...
