Abstract
This invention generally relates to a method of manufacturing hybrid parts comprising metallic and non-metallic materials at high temperature. During the method, a hollow metallic feedstock heated to a temperature in the austenite region may be placed in a die and filled with a non-metallic material in a viscous condition, after which the feedstock in the die is formed and then controlled-cooled to cause hardening of the non-metallic material in the region of contact between the metallic and non-metallic material. Afterwards, the semi-finished product is removed from the die and cooled to room temperature. The rate of cooling may be adjusted to generate compressive stress in the surface layer of the non-metallic material, which reduces the risk of cracking.
