The magnesium metal and/or the finishing manner which the deformation processing property between warm of the deformation processing material between magnesium alloy make warm improves, the deformation processing characteristic improver null magnesium metal between warm of the reduction manner of the attaching kimono which comes in contact to the die for the said processing, manner, and the said material which improve the deformation processing property

摘要

PROBLEM TO BE SOLVED: To improve the working property of a warm plastic working material made of magnesium metal and/or a magnesium alloy, that is, to greatly improve the efficiency of working by sharply reducing the frequency of changing and cleaning of a finishing machine (die, for example)by sharply reducing the deposit of the material stuck to the working machine in the warm plastic working of the material and to improve the freedom degree of the working in the warm plastic working of the material by making it possible to comply with a wide critical drawing ratio by one kind of material.;SOLUTION: This method is a surface treating method for improving the warm plastic working property of the warm plastic working material made of the magnesium metal and/or the magnesium alloy, in the surface treatment, the surface of the material is treated by mechanical surface grinding or pickling. The material the surface of which is treated by the surface treating method. The plastic working goods made of the magnesium metal and/or the magnesium alloy are obtained by plastically working the material.;COPYRIGHT: (C)2007,JPO&INPIT
