NON-DESTRUCTIVE DETERMINATION OF VOLUMETRIC CRYSTALLINITY OF BULK AMORPHOUS ALLOY |
| 摘要 |
A method comprising: constructing a master curve plot comprising a plurality of reference curves, each reference curve representing a relationship between volume and temperature for one of a plurality of reference alloy samples having a chemical composition and various predetermined degrees of crystallinity; for an alloy specimen having the chemical composition and an unknown degree of crystallinity, obtaining a curve representing a relationship between volume and temperature thereof; and determining the unknown degree of crystallinity by comparing the curve to the master curve plot. |
