WebApr 20, 2024 · Abstract. Literature data on the surface tension of copper σ s in the solid phase are reviwed. The σ s values obtained by different researchers using the zero creep method are given. The most reliable result is an σ s obtained by the zero creep compensation method in vacuum. At 1253 K, it is (1520 ± 14) × 10 −3 J m −2. WebMechanical Properties at High Temperatures. Gold additions improve the creep resistance of platinum at moderately high temperatures.
