Cold - hot isostatic pressing of superalloy composites
High volume production of superalloy metal matrix composites (SMMCs) processed at high temperature (above 1000 °C) under clean environmental single-stage conditions is cost inhibitive. Special designed equipment on handling, processing and finishing are usually needed. As the aircraft industry moves...
