Introduction
The high energy mechanical ball milling of alloying powder is an important way for the preparation and synthesis of fine and new materials.
During ball milling, high mechanical energy can induce chemical reactions or altering of structure and characteristics of materials, and decreases reactive activation energys significantly.
Alloying of some materials are difficult using traditional melted process.
However, by the use of high energy ball milling, powder alloying and even synthesis of quasi-steady, non-equilibrium or new materials are available.

Introduction
Shape memory alloys (SMAs) have the ability to perform both sensing and actuating functions and have consequently been identified as potential materials for various functions within turbo-engines components.
The introduction of this category of materials in aerospace gas turbines however requires SMAs with martensitic transformation (MT) temperature above 250°C, which is well over MT temperatures of commercially available materials.
As it is known for multiple shape memory materials, mechanical characteristics are better when the transformation temperature Ms is less than half of the melting temperature Tm.

The charge is modeled using special purpose material model named High Explosive Burn characterized by the Jones-Wilkins-Lee EOS [2].
The shape of the explosive material is cut out from the domain defined by multi-material ALE elements using “initial volume fraction geometry” option.
Those materials are quite similar, however to compare them, the results must be scaled, see [7].

The second challenge is the selection of the course materials.
The small screen size, limited navigation, and loss of contextual information of the course materials in addition to unintuitive technology can lead to a fragmented and frustrating learning experience.
And some learners may suffer from reduced psychological comfort and may find themselves spending unnecessary time trying to become better oriented with reading materials delivered on mobile devices.
For the teacher, in this layer, we provide lesson and course management service for teachers, they can open a new course, upload materials associated with the topic, review student's learning status.
