Research and Application of Melt Heat Treatment |
| |
| Abstract: | The concept of melt heat treatment is put forward for the first time.The related processing,research and application development are summarized.It is pointed out that material microstructure and properties can be improved significantly by control of pre solidification melt state and the succeeded cooling rate based upon the effects of temperature on melt microstructure.While mass research work dealing with the effects of cooling rate on material microstructures has been done,effects of melt state on solidification processing have hardly been considered deliberatly by researchers.Vast application vacancy of this technology will be explored because of its great advantage of low cost,simplicity and evident improvement of material properties. |
