Intermediate annealings may be required to reach the required ductility to continue cold working a workpiece, otherwise it may fracture if the ultimate tensile strength is exceeded.
32.
This steel contains greater concentrations of residual elements that cannot be removed through the application of oxygen and reinforcing bar and other products that require little cold working.
33.
Critics say Green and president Roger Headrick have created a cold working environment that pays too much attention to the bottom line and too little to employee needs.
34.
Drawing is usually performed at room temperature, thus classified as a cold working process, but it may be performed at elevated temperatures for large wires to reduce forces.
35.
When steel is formed by press-braking or cold rolled forming, there is a change in the mechanical properties of the material by virtue of the cold working of the metal.
36.
Laser peening is unlike the other manufacturing processes in that it neither heats or adds material; it is a mechanical process of cold working the metallic component to impart compressive residual stresses.
37.
Hot working of nitinol is relatively easy, but cold working is difficult because the enormous elasticity of the alloy increases die or roll contact, leading to tremendous frictional resistance and tool wear.
38.
The tool used to flare tubing consists of a die that grips the tube and a mandrel that is forced into the end of the tube to form the flare by cold working.
39.
This cold working increases the strength and hardness of the alloy, and the defects caused by plastic deformation tend to speed up precipitation, increasing the hardness beyond what is normal for the alloy.
40.
Coining is a cold working process ( similar to forging which takes place at elevated temperature ) that uses a great deal of force to plastically deform a workpiece, so it conforms to a stamping.
