Functionally gradient materials (FGM) are materials whose properties change in their volume.
Higher high-speed steel density in pressurelessly formed materials, in comparison with the high-speed steel density in compacted and sintered materials, is caused by higher carbon concentration.
Hence the sintering temperature corresponding to the maximum density of the pressurelessly formed materials is lower in comparison with the materials made using traditional powder metallurgy methods.

Furthermore, it also produces other problems such as the high consumption of materials and power [1-3].
With the developing of economy and technology, students who major in materials science are demanded to own not only solid foundation for a broad range of knowledge, but also strong practical, innovation abilities and good overall quality [4-6].
On the basis of other prior professional courses including "Fundamentals of Materials Science" "Metal Material and Heat Treatment", "Metallurgical Testing Technology", the educational reform is strengthened on the course "Carbon Steel Heat Treatment Experiment".
After optimization design, the experimental contents include multiple metal materials and more varieties of heat treatments.

The best possibility for developing such a material is combining it with composite materials for dental fillings.
Examinations of fluorine release were performed for A,B,C,D materials.
The fluoride release increases strongly after cyclic loading process of the analyzed materials. 4.
