The United States became interested in gas turbine development around 1905. From 1910-1915, austenitic ( γ phase) stainless steels were developed to survive high temperatures in gas turbines. By 1929, 80Ni-20Cr alloy was the norm, with small additions of Ti and Al. Although early metallurgists did not know it yet, they were forming small γ' precipitates in Ni-based superalloys. Th… WebAs indicated in the first figure - the strength of copper is reduced to approximately. 95 % at 100 oC. With an Ultimate Tensile Strength - σ u - of 220 MPa for copper - the strength is …
