Studies on Martensite Transformation in Iron-Nickel Alloys (3rd Report). Coexisting Range of Schiebung and Umklapp Transformation

Toshio Honma


Abstract:

In dependence of Ni concentration, the temperature range of the Schiebung and Umklapp transformation was determined by means of microscopic and acoustic methods. The results obtained were as follows: (1) The two types of transformation can take place in specimens of the same Ni concentration by supercooling to low temperature. (2) The highest temperature in which the Umklapp transformation can take place is always lower than that of the Schiebung, and is about -10° independent of nickel content.
