Method and arrangement for heat treatment before the execution of sprayform techniques

A method for implementing pre-heat treatment before spray forming begins to achieve stress control in the manufacture of a spray formed metallic article, comprising:

• preheating at least one of a spray forming cell environment and a mold substrate disposed within the spray forming cell environment to a preselected initial temperature;
• initiating application of a metallic spray forming material at a preselected initial application temperature of the spray-forming material upon the mold substrate in the manufacture of a spray formed article;
• and
• causing preselected substantially homogenous initial metallic phase transformations of the spray forming material from an austenite phase of the spray forming material to a substantially homogenous initial distribution of commingled metallic phases consisting of a predetermined proportion of at least one of a bainite phase and a martensite phase of the spray forming material and a predetermined proportion of the austenite phase of the spray forming material;
• wherein the substantially homogenous initial metallic phase transformations are caused at least in part via a predetermined relationship between the initial application temperature of the spray-forming material and the initial temperature of the at least one of the preheated cell environment and the preheated mold substrate;
• and
• wherein preheating at least one of the spray forming cell environment and the mold substrate further comprises preheating the spray forming cell environment to the initial cell temperature that is less than the initial application temperature of the spray-forming material.

A method for implementing pre-heat treatment before spray forming begins to achieve stress control in the manufacture of a spray formed metallic article, comprising:

• preheating both a spray forming cell environment and a mold substrate disposed within the spray forming cell environment to a preselected initial temperature;
• initiating application of a metallic spray forming material at a preselected initial application temperature of the spray-forming material upon the mold substrate in the manufacture of a spray formed article;
• and
