Temperature is one of the major factors affected the interface strength and formability on warm forming of multilayered sheet metal.
In this study, the mechanical properties and formability of a Mg-Al-SUS clad sheet are investigated.
Among these processes, roll bonding is the effective method due to manufacturing cost, however, it is difficult to simultaneously achieve all of the required properties and conditions such as bond strength, formability, thermal profiles in the dies, etc.
Formability is the important factor needed to deform a clad sheet into a final shape.

Through finite element analysis, the ratio of minimum radius of thickness to the cutting edge tool radius under different conditions of cutting speed and cutter blade was got, the size effect, stress field and cutting force under different cutting depth was got, and comparing and analysis the results, getting the various factors impact on the size effect of micro-milling, it provide a basis for the actual processing.
As well known in micro cutting, the minimum cutting thickness is dependent on the cutting edge radius and the physical properties of workpiece.
Considering that the factors affecting the minimum cutting thickness are more so as to be difficult in determining its value, the popular method in actual production is to calculate in terms of the cutting edge radius [7, 8].
Principal Cutting Force Variation Affected by Size Effect In this segment, the influence of size effect on the principal cutting force was investigated.

So, it is very important to understand material defect shape and distribution, and its effect on mechanical properties exactly.
Introduction It is very important to understand the effect of defect on fatigue properties because the practical properties of engineering materials are often determined by the defect.
In the case of casting defects, however, they are still not possible to fully account for not only the effect on the properties, but also the condition by NDT because of its complex shape and small size[3], even though several methods for predicting the mechanical strength[4~6] and characterizing the defective condition[7,8] have been proposed.
As shown in Fig. 2 and 3, the relation between fatigue properties and the square root of total defect area estimated has very good linearity in log-normal plot with about 0.8 ~ 0.9 of determination factor.
The relation between fatigue properties and maximum defect size was also shown in Fig. 4 and 5.

To this end, we need to find the main factors affecting tissue engineering scaffold degradation in order to grasp the control methods of degradation rate.
These five factors that affect the degradation process is the most critical factor, the ideal degradation modeling should be integrated over five key factors to consider.
Factors such as the first, the impact of molecular structure, there is no one model relates to this; currently most researchers take 1-2 influence of factors into account in the modeling according to the process of degradation phenomena.
Herrera et al [25] established the two-scale model which combined macroscopic mechanical properties of bone with microscopic model of scaffold degradation and scaffold bone growth.
