In order to confirm the Wang's prediction which asserts that the transformation temperature (Ms temperature) is proportional to the valence electron concentration ("total (3d+4s) electron number" divided by "total atom number"), effects of additives V, Cr, Mn, Zr on the Ms temperature of TiNi compound were examined by means of electroresistivity measurements. The results are as follows : 1) Contrary to the Wang's prediction, Ms temperatures decrease with increase of valence electron concentration in the range when the concentration is over seven ; 2) It's decreasing rates are the same in the case of addition of V and Mn, but in the case of addition of Cr it is larger than the former ; 3) As the Ms temperature decreases by adding Zr, it becomes clear that size effect must be also taken into consideration.
