| Research Abstract |
The measurement of the mechanical property intended to do the structure analysis of the microstructure with the corrosion action more as to the preparation of the ribbon which a Mg-Sc mother alloy was used for on original schedule. It failed in the purchase of Sc of the cheap quantity which it tries variously and which is necessary for this research, and the sample preparation until it reached a research start couldn't be done.
By the way, as a separation process of the Mg alloy which contains 希 soil kind, for example, with a Mg-Gd alloy, it is reported as follows,
Super saturated solid solution →ss''(D0_<19>,Mg_3Gd) →ss'(bco,Mg_<15>Gd_3)→ss(fcc,Mg_5Gd)
It is very important to clear the matter whether the separation look connected with hardening directly is which when still the mechanism of these look metamorphoses has various views and the strength of this alloy is improved.
So, the matter that it gets foundation data about prescription hardening of the heat-resistant Mg alloy and the relations of the separation action is made the principal object, it is done around the detailed organization observation by the high resolution Noh play permeation pattern electron microscope, characteristics are explained like crystal study of each separation look and like a study of the form, the structure of the formation thing of a stage of the early stages of separation, obviously.
It could think that magnesium of a mother look and a thing like a meeting body by Gd and Y were formed by the products after quenching was specially put right after solution heat treatment from grain-shaped contrast's already having been observed.
