    2021-7-19 · Creep resistance of materials can be influenced by many factors such as diffusivity, precipitate and grain size. In general, there are three general ways to prevent creep in metal. One way is to use higher melting point metals, the second way is to use materials with greater grain size and the third way is to use alloying. Body-centered cubic (BCC) metals are less creep resistant in high temperatures.

    The ability of a polymer to biodegrade is independent of the origin of its raw material. Instead it strongly depends upon the structure of the polymer. For example, whilst some bio-based plastics may be biodegradable ( e.g. polyhydroxyalkanoates) others are not (e.g. polyethylene derived from sugar cane). Source; Frost & Sullivan, 1998.
