VDM® Alloy C-264 is a nickel-based super alloy developed by VDM Metals. It was developed specifically for corrosive high-temperature environments, as those found in modern high-performance turbochargers. VDM® Alloy C-264 is an age-hardenable alloy with an austenitic microstructure. The alloy features a high temperature strength as well as excellent creep resistance at temperatures of up to 950 °C (1,742 °F). VDM® Alloy C-264 is by far superior to similar materials such as VDM® Alloy C-263 (2.4650) in terms of creep resistance especially. VDM® Alloy C-264 is characterized by: Excellent processing properties in solution-annealed condition Very good creep strength up to 950 °C (1,742 °F) Good oxidation resistance up to approx. 1,050 °C (1,922 °F) Good mechanical short and long-term properties, as well as good fatigue strength in age-hardened condition Microstructural properties V DM® Alloy C-264 is an age-hardenable alloy with an austenitic microstructure. Beside the main component of nickel, it contains 25% chromium, 20% cobalt, 5.5% molybdenum, 1.7% titanium and 1.1% aluminum. The alloy fea-tures a high temperature strength as well as excellent creep resistance at temperatures of up to 950 °C (1,742 °F). This is achieved by a combination of hardening mechanisms, such as solid solution solidification, carbide hardening and γ’ hardening. VDM® Alloy C-264 is therefore far superior to similar materials such as alloy VDM® C-263 in terms of creep re-sistance especially. This long-term stability is realized through a γ’ phase more stable at high temperatures, the main reinforcing phase that can no longer change into the undesired η phase.
