11. The combination of heat treatment and cold working is essential in controlling the properties of nitinol. 12. Most non-ferrous alloys that are heat-treatable are also annealed to relieve the hardness of cold working . 13. Manual transmission gears are an example of automatic hot forging used in conjunction with cold working . 14. Swaging is usually a cold working process; however, it is sometimes done as a hot working process. 15. So as knife steel it depends on other hardening methods such as alloying elements and cold working . 16. This process is easily observed while working a material ( in metals cold working of process ). 17. Overpeening will cause excessive cold working of the surface of the workpiece, which can also cause fatigue cracks. 18. Often intermediate anneals are required to counter the effects of cold working , and to allow more further drawing. 19. The cold working process also reduces waste as compared to machining, or even eliminates with near net shape methods. 20. During cold working the part undergoes work hardening and the microstructure deforms to follow the contours of the part surface.
