Study on a new method for the super-plasticity shaping -- laser super-plasticity shaping on the vacuum negative pressure condition

摘要

In the paper, based on outlining the making principle of the metal material super-plasticity and some making methods, a new making technology is proposed on the super-plasticity -shaping aided by laser in the vacuum negative pressure condition.The paper discusses the laser beams coupling characters in making process and the super-plasticity-shaping technology of the alloy materials, gives the shaping conditions of the typical materials for the vacuum negative pressure case.
