During process of vacuum heat treatment gas quenching pressure and gas quenching manner are the critical factors which will determine the microstructures and mechanical properties.
In other words, influence of aging treatment on mechanical properties is weakened gradually with increasing cooling rate.
Therefore, mechanical properties of cylindrical specimens are logically more excellent than those of flat specimens.
Although there exist differences between cylindrical specimens and flat specimens, variation rules of mechanical properties are similar.

Austempered Ductile Iron (ADI) is a new generation of cast iron materials developed in recent decades; but its excellent comprehensive mechanical properties make it become hard-machining material.
The main factors that affect the prediction of cutting force were analyzed with experimental data.
Because of the excellent mechanical and physical properties of ADI, it has been widely used in many fields, such as ships, aerospace and heavy industry.
But how machining ADI becomes a key issue due to its excellent comprehensive mechanical properties which make it become hard-machining material.
The specific cutting process must be analyzed to minimize the controllable influencing factors and remove minor impact factors.

The coating binder in cross-section of coating layer will be migrated, the binder concentration will be different in z-direction of coating layer, which affect some properties of coated paper.
The paper studied the effects of coating progress on binder migration and affected factors.
Numerous and related factors affect binder migration, such as coating process, coating color formulation, base paper properties, coating method, drying way and drying speed, binder types, pigments and so on, therefore so far it is difficult to find a migration rate or concentration distribution theory equation or empirical formula to describe the binder migration accurately.
The final result of coating binder migration in coated paper influences the structure and surface state, affects the coating operation and the properties of the coated paper.
This paper studied the influence of coating process, applied SEM-EDMA and ESCA to measure binder migration concentration [4-5], and further discussed on migration mechanism and the influence factors.
