WebOct 14, 2024 · Commonly used hot work die steel. (1) Steel for hammer forging dies. Generally speaking, steel for hammer forging dies has two prominent problems. One is impact load during work. Therefore, the mechanical properties of steel are higher, especially for plastic deformation resistance and toughness; the second is hammer forging. WebConsider the example of a man pushing a box across a rough floor at a constant velocity as shown in Figure 1. Since the friction force is non-conservative, the work done is not stored as potential energy. All the work done by the friction force results in a transfer of energy into thermal energy of the box-floor system. This thermal energy ...
