Introduction In the modern mechanical engineering, various methods of wear-resistant coating with functional materials, including powder coating, ceramics and heat-resistant polymers, single and multicomponent metal and composite electroplated coatings, carbide coatings, etc. are widely used for surface hardening of agricultural machine parts made of structural alloyed steels [1].

Introduction In recent years, there have been increasing interests in developing bulk metallic glasses (BMGs) with great glass-forming ability (GFA) owing to the unique combination of properties, different from that of conventional materials and the potential engineering applications [1-9].
However, the engineering commercialization of these BMGs as structural materials is hindered by their limited GFA, low thermal stability and unsatisfactory manufacturability [9].

Therefore, the international promotion of Chinese language to achieve six major changes: the more a single foreign language teaching in all directions of Chinese Language Council International; from the foreigners, "Please come in" Learning Chinese into "Please come in" and "going out" a combination ; from professional Chinese language instruction into a mass, popular type, application type Chinese teaching; the education system into a simple teaching system of internal and external services to the community and serve the state, government and civil, domestic and abroad to advance the cause; promotion model implementation of the scheme undertaken by the government into a government driven by the market;-face from the paper-based materials to promote the main changes to the multimedia network [2] [3].

As we know, the Al3Sc particles are initially fully coherent with the matrix,and there are at least three possible grain boundary/dispersoid interactions when an advanceing high angle grain boundary is passing a coherent Al3Sc dispersoid: The Al3Sc dispersoid retains its global orientation relationship and thus loses its coherency with the surrounding matrix; The Al3Sc dispersoid rotates as the grain boundary passes; The Al3Sc dispersoid dissolves at the grain boundary and re-precipitates in the recrystallised grain.
