As the demand for hot rolling strip increase in the market,the rolling stability of thin strip had become a main technique issue in the hot strip mill ,this psper introduce technique factors influencing upon the rolling stability, which are summarized for the rolling practice and analysis has been done as well.

The factors which influenced the rolling stability in the hot continuous rolling were analyzed in the paper.

The stock stability in grooveless rolling is systematically investigated.

This paper puts forward the stable rolling conditions when rolling thin plate below 8mm on 4high plate mill: composite roll convexity Δ≤-05mm, the rolling speeds of upper and lower roll are same, the loads of upper and lower main motor are same or nearAt the same time, two kinds of rollchanging regulations for ensuring stable rolling are intorduced in order to ensure low roll consumption

The mechanical stability of retained austenite and its effect on wear resistance are discussed.

To take NiTiHf and NiAl alloys for example, the authors discuss the considerable factors of developing high temperature shape memory alloys, including workability, phase stability, mechanical stability and cost of the materials.

There is established a linear dependence of percent of strain inducedmartensite transformation of the retained austenite in the steel upon tensile strainThe mechanical stability of retained austenite can be indicated by Ks,the reciprocalof the strainghe line slope.
