Introduction The implants used in orthopedic surgery are made of materials compatible with human tissues.
Biocompatible means the ability of a implant to be composed by materials that not induce a biological response in the adjacent tissues.

The parameter C represents an energy penalty for slip confined to one plane; i.e., materials that have a tendency to twin might be expected to have a large, positive value of C.

There were else taken two piece of fragments, there was a visible boundary on it, indicating that it had two materials; individually drilling on two materials to take two iron chipings to test chemical compositions of the two materials; with metallographic grinding wheel cutting machine along the longitudinal direction, some specimens were cut with both section parallel, the specimen thickness of 10 mm circumferential and radial height of 78 mm, after flat finishing, from the roll surface at the radial was its Rockwell hardness measured on the section; then having hot acid etched to take a macroscopic test; on macroscopic specimen there was a visible light interface which divided the specimen into two layer materials, from the roll surface to the interface of the outer material, thickness of about 52mm, with A, B respectively indicating said the outer layer near the roll surface zone and interface zone; below interface the inner layer material C zone(see Figure 2); the metallographic polished
Fig.3 Smooth rupture zone Fig.4 Smooth sector Figure 5 circumferential crack on the roll cross section on the roll boundary layer in the back-up roll barrel Chemical Composition.The chemical composition test results of outer and inner materials of the roll barrel fragments and the chemical compositions described in the material category of "high chrome centrifugal compound Ⅱ" and "pearlitic spheroidal graphite Ⅰ" of the China National Standard GB / T 1504-2008 "Cast Iron Roll" were shown in Table 1.
The high Cr content of inner material might be due to the chromium diffusion of outer layer material.
