摘要：
Method and apparatus for controlling a spray-forming process incorporating time, temperature, and transformation dependent stress relief techniques involves the manipulation of both temperature and time for strategic phase changes that result in a specific and planned volumetric increase. This manipulation is made based on controlling ongoing spray parameters to spray-form an article having a mixed-phase and interspersed makeup of metallic phases that minimizes residual stress in the article.
