Creep deformation is important not only in systems where high temperatures are endured such as nuclear power plants, jet engines and heat exchangers, but also in the design of many everyday objects. For example, metal paper clips are stronger than plastic ones because plastics creep at room temperatures. Synthetic diamond is the hardest known material, where hardness is defined as resistance to indentation. The hardness of synthetic diamond depends on its purity, crystalline perfection and orientation: hardness is higher for flawless, pure crystals oriented to the direction . pressure steam at temperatures over °C causes breakdown of the siloxane polymer and a decline in the properties of the rubber. This effect can be ameliorated by adjusting the silicone rubber formula, selecting a proper curing agent, and/or post-curing. SELECTION OF DIE MATERIALS AND SURFACE TREATMENTS FOR INCREASING DIE LIFE IN HOT AND WARM FORGING. the dies are subjected to high contact pressures and temperatures. The selection of the die material, hardness and coating is critical for Thermal and mechanical properties .
Jun 14, · High temperatures especially affect steel, and its toughness will be reduced. This is because as the temperature rises, there is a correlated increase in the thermal vibration of atoms, which causes changes in the structural properties of the metal. Many aluminum alloys, meanwhile, will retain their mechanical properties at high temperatures.
