Little did we know with respect to linearity of bevavior of the martensite start temperature in the particular valence electron range, which is somewhat omitted in the literature on this subject. Therefore in order to shed more light on this intriguing phenomena new set of alloys was prepared. The alloys were homogenised at 1000 degC for 6 hours. They were sealed in quartz ampules beforehand but unfortunately while in the oven three of the tubes broke. The alloys were therefore subjected to chemical analysis to estimate possible changes in composition and the effects of oxidation. The analysis performed in the bulk of the materials showed that no major compositional changes occured.
